On the cleaning of metal finds from the London and the Rooswijk

I am pleased to introduce this week as my guest blogger Elisabeth Kuiper, who has just completed an internship with Historic England. She tells us about her recent experiences in the conservation of metal artefacts from two designated shipwrecks:

Most historic ships are full of iron: think of nails and bolts in all sizes, ship equipment, rigging elements, chains, anchors, iron cannons and all sorts of different tools used on the ship. This iron, in the unfortunate event of ending up on the seabed, usually grows very bulky corrosion products eventually covering the original surface of an object. Iron objects from a maritime archaeological context are thus very often found as mysterious and unrecognisable lumps, known as concretion, as they have become covered by a thick formless mass of corrosion which can incorporate sediment and shells, and also different objects in the vicinity. In order to understand the concretion and what is, or used to be, inside it, the conservator uses X-radiography. X-radiography gives the opportunity to investigate the concretion without damaging it: dense areas or voids will show up on the image and so may be able to tell what has caused the concretion.

Once it is clear that the concretion may hold something worth investigating further, the conservator will start off mechanically cleaning it. Corrosion products are taken off layer by layer until the original surface of the object is found. In the process of cleaning other artefacts which may not have been seen previously on the x-radiograph, can be found trapped in the corrosion layers, for example, pieces of glass, ceramics or small metal objects.

Unlike any other metal, in an advanced stage in the corrosion process the iron of the original object can have migrated entirely to its corrosion layers, and we are left with a void that retains the shape of the object precisely. If needed, these voids can be filled with a silicone rubber or casting resin. Once all concretion is removed the conservator is left with a perfect cast of the object that would otherwise be lost forever.

I am a Professional Doctorate student in conservation and restoration at the University of Amsterdam, specialising in metal conservation, and have been working at Historic England on an archaeological conservation work placement for the past months. My main focus during my time at Historic England was the remedial and investigative conservation of finds from the protected wreck sites of the Rooswijk and the London. The London was a Royal Navy warship that went down in the 1665 after an accidental explosion aboard the ship, and many different objects were recovered during the salvage operations between 2014 and 2016.

The Rooswijk was a Dutch East Indiaman that ran aground on the Goodwin Sands, off Kent, in the winter of 1740. The shipwreck was partly excavated and recorded in the summer of 2017, after which the finds were taken to Historic England storage facilities for assessment, analysis and conservation.

During my time at Historic England I have worked on quite a diverse range of finds from both wreck sites, but what they all had in common was the various amounts of iron corrosion on the object’s surface. As previously mentioned, this is quite typical for maritime archaeological artefacts, which (as we will see) can even be totally enveloped in iron corrosion. A few of the more straightforward objects I have worked on were from the London:

In Figure 1 above we see a hammer, with iron corrosion products covering the original surface. The hammer was cleaned using a pneumatic tool called an air-scribe, which can be seen as a small jackhammer. It is ideal for removing concrete-like iron corrosion products, with the x-radiograph was used as a guide during the cleaning. When looked at carefully, the x-radiograph clearly shows the typical lamellar structure of corroded wrought iron. Wrought iron is essentially pure iron containing less than 0.2% carbon by weight. The main compositional variation is in the presence of slag inclusions. When worked these slag inclusions are forced out in the direction of working. On the seabed not only does the metal surface corrode, but also the walls of the slag inclusions, as seawater is able to penetrate deep into the metal. As a result the metal shows a wood grain-like appearance, typical of wrought iron recovered from shipwrecks.

The same became clearly visible as corrosion was cleaned away on a rigging element called a deadeye:

Up to now I have discussed corroded iron objects. Surprisingly, it’s not only objects made from iron that can become covered by a thick iron concretion crust. As we will see in the next images, copper alloy objects can also become unrecognisably changed due to maritime corrosion processes:

The artefact shown here is a copper-zinc alloy object, presumably a pan of some sort. Probably it will have had a handle that was riveted to the pan itself. These rivets were already visible on the x-radiograph, but were uncovered during cleaning.

Cleaning of maritime archaeological finds can be rewarding and satisfying work, in the sense that the disfiguring corrosion layers are slowly removed to reveal a recognisable object once more. Sometimes these objects can even be in quite a good condition. The cleaning of concreted artefacts can almost be seen as a mini-excavation. To illustrate this, I will show one last treatment on a concretion, which furthermore posed quite a challenge:

In this case, cleaning of the concretion was more of a challenge because of the mixture of elements and materials in it. The concretion consists of approximately 17 copper alloy rings, 1 silver coin and over 400 tiny glass beads. What was left of the iron (mostly nails and/or small bars), as explained earlier, were just voids. The concretion itself proved to be a harder material than the glass beads, which tended to shatter when the air-scribe came close. Mechanical means thus did not seem to suffice to remove the beads from the concretion, but a chemical treatment would be difficult to select, as the other metals would react to the chemicals as well as the iron concretion. As a first step, the concretion was mechanically cleaned until beads and artefacts, including voids, started appearing:

Because initial research proved the voids to be ‘just nails’, the decision was made to record them as best as possible, but then to sacrifice them in the bigger scheme of things. This way, the concretion could be broken apart in smaller pieces that offered the opportunity to treat them separately from the coin and rings. This work is still ongoing and consists of a combination of mechanical and chemical treatments in order to gently dislodge all the different objects from the concretion for further study.

Thank you to Elisabeth for sharing the problems and processes of conserving concreted objects from the London and the Rooswijk, and which complement previous blogs by our conservators: see links below. We hope she has enjoyed her time with us and wish her all the best for the future.

Diary of the War: February 1918

HMS Brown Mouse

If ever there was a name that sounds most unlikely for a warship, this is it. The Brown Mouse was no Dreadnought, Implacable or Dauntless . . .

Yet she went to war and what better cover could there be than such an innocuous-sounding name? All of 42 tons, she was built as a Brixham trawler, and launched in February 1908, official no.125110, a detail which might seem trivial or boring, but I’ve included it for a reason. (1)

In her original register entry Brown Mouse was described as a trawler, and assigned a fishing number of BM 276, but from the outset it seems that she was owned by the same man who later operated her as a yacht, Evelyn Pearson. (2) At least one other example of a yacht built on Brixham trawler lines still survives on the National Register of Historic Vessels. This vessel is the Golden Vanity, which was built in the same year at the same yard, Sanders & Co. of Galmpton, for the marine artist Arthur Briscoe, and this vessel was assigned the very next official number in the sequence. (3)

She appears to have fished locally at least in 1909, since during that year she was crewed by four or five men, with William Kingdom of Brixham as skipper. (4)

She was then fitted with an auxiliary steam engine by Simpson, Strickland & Co. of Dartmouth in 1910, whereupon she was re-registered, again at Brixham, due to the ‘material alterations’. She was no longer described as a trawler in the new registry, and it may be at this point that Evelyn Pearson and Brown Mouse became “regular” visitors to Brixham. (5) 

Then the war came and Evelyn Pearson joined up in September 1914, becoming a captain in the 12th Battalion, King’s (Liverpool) Regiment. He would have been about 39, but he had previous soldiering experience in the Lancashire Fusiliers in the 1890s. (6)

In the meantime, the development of the Q-Ships as, effectively, fisheries protection vessels, had begun during 1915, as fishing smacks were targeted off the east coast, as described in our July 1915 post. Similar attacks took place thereafter on a fairly regular basis on the North Sea and Channel coasts, with enemy activity intensifying at intervals.

Protection against mass sinkings of the fishing smacks came from among their own: one vessel from each fleet would be commissioned as a ‘Special Service’ vessel to guard their fellows engaged in fishing. Their diminutive size inevitably led to their designation as ‘Q-smacks’, but they were no less ‘Special Service’ vessels for that. Some even engaged U-boats directly, as Inverlyon had done in defending the Lowestoft smacks, covered by one of our past blog posts for August 1915.

Sadly Captain Pearson was killed in action in Flanders on 8 January 1916, at the age of 41. (7) The next phase of his yacht’s history is slightly unclear. Her registry at Brixham was closed on 27 November 1916 ‘in consequence of material alterations’, with her prior ownership stated as Captain Pearson, Thomas Kirkland Rylands, and the Hon. Earl Stanhope, and on the same day her ownership is recorded as transferred to H F Eastick of Great Yarmouth. (8) Eastick had already lost other vessels during the war, such as the Copious in 1914. Brown Mouse would not have been the first or last Brixham trawler to have transferred to the Lowestoft or Great Yarmouth fleets. 

It seems, however, that she would remain within her familiar waters in and around Brixham, rather than in service with Eastick, for one month later she was a ‘Special Service’ vessel. Perhaps Earl Stanhope, who was involved in the War Cabinet, had drawn official attention to her as a suitable vessel for the purpose.

Despite Inverlyon‘s success, it wasn’t always possible for the Q-smacks to defend their charges. On 8 June 1917, another sailing Q-smack, the Prevalent, was unable to assist when four Brixham smacks were sunk in the fishing grounds off south Devon, in full view of Start Point. One of those vessels was the Onward, built in 1907, and assigned an official number of 125101. Other vessels also assigned numbers from the same batch of official numbers allocated to Brixham, all built locally at around the same time as Brown Mouse and Golden Vanity, had also fallen victim to German submarine attacks: Markum on 17 April 1917, Boy Denis on 26 April, and Rupee on 4 October 1917.

One contemporary writer suggested that the Prevalent incident prompted the retrofitting of an auxiliary motor engine aboard Brown Mouse. (9) With her existing engine it is more likely that she was identified as a suitable candidate capable of speeding to the site of any trouble with enemy submarines, and replaced the Prevalent on the Brixham station.

However her participation as a Q-smack locally came about, the circumstances of her loss suggest that Brown Mouse was out on patrol with the Brixham trawlers on 28 February 1918. Unlike the other vessels with whom she was registered, however, she was not a war loss and so is not mentioned in many of the standard sources. Details of what happened next were given by the skipper of another local trawler, the Leonora Minnie, who had a narrow escape when the Brown Mouse caught fire and seemed headed for his vessel, the worst nightmare for any skipper of a wooden vessel, but, fortunately, she cleared the Leonora Minnie’s bows. Brown Mouse was subsequently ‘lost by fire off Berry Head’, with the local RNLI being called out to assist, a service which cost them £24. Fortunately, it seems that no lives were lost on this occasion. (10)

Trawler, yacht, and Q-Ship: small, as her name implied, Brown Mouse was sufficiently versatile to operate in all three roles, and to do so locally in every case. Her story highlights a mini-landscape of war off Brixham, in which fishing vessels came under attack, leisure cruising ceased, and small ships took on a modern enemy.

With many thanks to John and Sandie of Brixham in Pictures for their kind assistance with this article.

Diary of the War: January 1918


This week we look at a wreck in the Bristol Channel which was first published in most British newspapers on 10 January 1918, six days after the ship was lost on 4 January.

Rewa was built as a liner in 1906 for the British India Steam Navigation Co., along with her 1905 sister, Rohilla, both vessels named after provinces of India. Their careers paralleled one another: both were converted from passenger service to troop transports, taking part together in the Coronation Fleet Review, 1911, and on exercises in 1913 off the Humber. (1) From transport service it was but a short step on the outbreak of war to conversion to hospital ships. Both would be lost in that service and Rohilla was featured in the War Diary of October 1914.

From 1915 onwards Rewa would become one of the familiar sights of the Gallipoli campaign, transporting men out from Suvla Bay to the depot at Mudros (Greek Moudros) to hospital at Alexandria or Malta, or back home. (2) On her final voyage she was bound from Mudros to Avonmouth via Gibraltar, where she had been inspected by a neutral Spanish observer to ensure her bona fides as a hospital ship. (3) There are some conflicts in the numbers on board, but the usual figures given are 207 crew, 80 medical personnel, and 279 wounded men (making a total of 566), although contemporary newspapers gave the rounded figures of 550 and 560. (4)

On his first patrol of the New Year was Kapitänleutnant Wilhelm Werner of the Kaiserliche Marine (Imperial German Navy) in U-55 off the coast of Cornwall. (5) For almost a year now, Germany had waged unrestricted submarine warfare, torpedoing ships without warning, but, by the terms of the Hague Convention, hospital ships were exempt from attack. They were distinctively painted with a white hull and the internationally recognised symbol of the Red Cross, and were to be lit in the dark for night recognition. The Rewa was accordingly proceeding up the Bristol Channel, ‘brilliantly lighted’ as demanded by the convention. (6) The Captain stated: ‘We had our Red Cross flag up and our lights had been lit at sunset – viz., steaming lights, navigation lights, and Convention lights, and they had remained and were alight at the time of the explosion. All the lights were electric. The ship was hit abreast of the funnel on the port side, as near amidships as possible.’ (7)

Thus when Werner fired the torpedo which caused the explosion off Hartland Point in the Bristol Channel, he must have known that he was contravening the Hague Convention. The captain had seen suspicious lights just before the torpedo struck, and ported his helm, but had not verified the identity of the vessel before the torpedo actually struck. (8)

The explosion is said to have extinguished the lights (many newspapers reported that a fortuitous find of a candle afforded some light, although, less dramatically, emergency candle lamps as a backup system were, in fact, lit) (9) and the ship began to settle. Fortunately for the evacuation, the vessel remained on an even keel before she finally sank, the sea remained calm, and there was time to send a distress call. Within 20 minutes everyone was on board the ship’s boats, even the ‘cot cases’ who were unable to fend for themselves. Given the dark and the imperative for haste, it was impossible for everyone to gather up sufficient clothing to keep warm while exposed to a cold night on the sea.

‘One of the nurses gave all her heavy garments to cover the men who were very ill, and remarking this an officer transferred to her his overcoat’, according to one account that was widely repeated across the press. (10) The number of nurses aboard was put at three, which seems a very small number amongst such a large medical staff with so many patients to look after. (11)

Even as they bobbed about on the sea, the little flotilla of lifeboats kept together on the captain’s orders and burned flares to attract attention – another factor in the survival of so many. (12)

Miraculously, only three men were initially reported missing, believed killed in the explosion in the engine-room, but, in fact, four lascars of the Indian Merchant Service were killed and are commemorated on the Bombay 1914-1918 Memorial, Mumbai: Usman Ghulam Qadir, trimmer, Ali and Said Ahmad Umar, both firemen, and Sultan Shah Azad, paniwallah (water-carrier). (13)

‘Another steamer and three trawlers were speedily on the scene’, although ‘speedy’ might have been a relative term since they were in the water for three hours before being picked up. (14)

The rescue vessels belonged to the Swansea Patrol and survivors were accordingly landed there. (15) The Western Daily Press described the ‘piteous’ sight as survivors came ashore,which moved onlookers to tears: ‘a procession of maimed and limping men, some on the backs of others and all without boots, wended its way under willing hands of helpers to the Coal Exchange . . . all business being suspended, while others were taken to leading hotels . . .’ (16) Some of the survivors were suffering from shock and wounds sustained in the explosion: one of the rescued lascars was reliving the fire in his mind, and another man went about all day without complaint until collapsing in the evening, when he was found to have several broken ribs. (17)

Eighteen survivors were taken to the Dan-y-Coed Red Cross Hospital (18) while others were despatched onwards to Southmead Hospital in Bristol. (19) It seems that Dan-y-Coed was a specialist in prosthetics made by a member of staff, so perhaps that was where some of the ‘maimed’ men ended up. A Dr Harrison was himself a hospital case with dysentery. Another medic, one Dr Lambert, had served since 1915 aboard Rewa at Gallipoli and had found romance and marriage in 1917 with one of her nurses, Alice Lockhart. He was with Rewa to the bitter end, receiving compensation for the medical instruments he had been forced to abandon on the sinking ship, but it is not yet known if his wife was also aboard at the time. (20)

The official German position cast doubt on the possibility of a submarine attack and suggested that a mine had been responsible for sinking the vessel, but the news triggered worldwide condemnation. As it was the Rewa would be cited as a war crime for which Wilhelm Werner was held responsible, although he would ultimately escape prosecution for this and other attacks on shipping.

The lights may have gone out on the Rewa as the torpedo struck, but, a century on, we are able to shine a light on some of those affected, whose stories are not always told in the accounts of shipping losses during the First World War: ordinary men and women, British and Indian, patients and crew, walking wounded and those severely ill and maimed.

Diary of the War: December 1917

Shot Down off the Coast

By December 1917 the citizens of London were used to air raids at regular intervals: it was terrifying enough, although nothing like on the scale of the Blitz of the Second World War. The wreck highlighted today in this month’s War Diary is representative of a new form of accident out to sea which would become more prevalent as aerial warfare developed.

On 18 December 1917 another raid was carried out by around 16 to 20 aircraft of Bogohl 3. (Bombengeschwader der Obersten Heeresleitung, High Command Bomber Squadron, also known as the Englandgeschwader, or ‘England Squadron’.) Two groups of Gotha bombers flew in over Kent and Essex around 6.30pm with the aim of bombing London. Some of the bombers got through and inflicted damage on Lincoln’s Inn which can still be seen today.

Nevertheless, after the cumulative experience of several raids, there were now several lines of defence which prevented all the raiders reaching London. Firstly, anti-aircraft guns swung into action and turned at least some of the enemy away. Secondly, barrage balloons were moored to protect London, a response more usually associated with the Second World War. One contemporary headline, ‘Barraged Gothas’ implies that the balloons were a major factor in preventing the majority of the Gothas from reaching London. (1)

At this point I made an unexpected discovery and this is where I digress briefly. I’d already earmarked Frank Dobson’s image as an illustration to this post, having seen it in an exhibition earlier this year, and saw then the balloons protected Kynoch’s munitions factory. (2) Researching this article, I then discovered that this same factory at Corringham, Essex, was targeted early on in this specific raid. (3) Nor was this the only coincidence. One of the supervisors at that very factory was my grandmother – and I wonder now if she was there at the time or had already gone home for the day! (Here’s a photograph of female workers at Kynoch’s: my grandmother is the girl in the sailor suit.)

The third line of defence was aerial combat. Fighter pilots from the Home Defence Squadrons also took to the air to challenge and intercept the raiders, among them Captain Gilbert Ware Murlis Green of No.44 Squadron, Hainault Farm, Essex, in his Sopwith Camel. (4) Up he went in his single-seater to duel with the three-man Gotha bomber, crewed by Oberleutnant G von Stachelsky (pilot), Leutnant Friedrich Ketelsen, and Gefreiter A Weissman. Three times he went in to attack, and then, blinded by his own muzzle flash, he was forced to pull away, while the searchlights that made the Gotha visible to him also made him a target for its return fire. His fourth attack found its mark.

Green had not immediately downed his opponent, but damaged it enough for it to be doubtful if it could return across the Channel. The press took up the tale: ‘One raider was hit by gunfire and finally came down in the sea off the Kentish coast, two of its crew of three men being captured alive by an armed trawler.’ (5) 

As the aircraft crossed the coast, observers noticed it sounded as if it was flying low, and therefore clearly struggling, and then the sound of its engines was heard to cease suddenly out at sea. The “All Clear” was then sounded, followed by an offshore explosion shortly afterwards. Searches found the stricken aircraft and the trawler picked up von Stachelsky and Weissman, but Ketelsen had perished in the incident.

Ketelsen was a Danish-minority German from Pellworm in Schleswig-Holstein. A very interesting website, mostly in Danish, commemorates the Danish minority reluctantly mobilised into the German forces, with a page dedicated to Ketelsen. His name appears on a hand-painted memorial tablet which is very moving to see (if you follow the line across from the lower left-hand column to the right it leads easily to his name).

As for the rescued men, much was made of their youth and demeanour: one of the prisoners was described as ‘very sullen and dejected’, as well he might have been. (6)

It would have been absolutely freezing exposed at several thousand feet high on a cold December night, and the sea would have been no better. The two rescued crew were very fortunate to live to see another Christmas, even if it wasn’t exactly how they planned to spend it!

(2) Imperial War Museum, catalogue entry for The Balloon Apron, suggests that it depicts balloons over Kynoch’s factory at Canvey Island. However, Kynoch’s presence on the island was in the form of a hotel and powder hulks located just offshore, but no factory. Kynoch’s factory was at Corringham, Essex, and, given the multiple factories depicted in the background of the painting, it appears more likely that the image shows the industrial landscape around Corringham.

The Lizzie Lee and other stories from the night of 18-19 November 1893

It is my pleasure to close the year with another blog from my regular guest Jordan Havell as part of a double bill with today’s War Diary post.  Before we start the blog I’d just like to say that I recommended him in the Best Contribution to a Heritage Project by Young People category in the Historic England Angel Awards this year, for which he has been awarded a certificate of commendation.

Jordan has continued to research shipwrecks in his local area for these blogs and the information he has found in local newspapers and other records has given us extra information for our database records. A well deserved award for Jordan and a lovely note on which to end the year!

So here is his blog:

In the early hours of the morning of 19th November 1893, a coxswain from Mablethorpe lifeboat station saw a flare shown by a brigantine named Lizzie Lee of Goole. The vessel had drifted past the station and went ashore 2 miles south of Mablethorpe.

The weather was that of gales that had sprung up. Some newspaper accounts tell us the severe weather had started on the 16th November and got much worse – having reached hurricane force winds on the 18th. This was to lead to an exhausting weekend for the rescuers of the area which sadly led to confusion and errors.

The Elizabeth Berrey was launched to assist the Lizzie Lee. One report says 07.30am and the other says 08.00am. It was the first time that the Elizabeth Berrey had been launched in service. She rescued the crew consisting of 5 men and it is recorded that she was returned to station by road at 11am.

The Lizzie Lee was a schooner built of wood in 1856, and was a sailing vessel. She was a cargo ship, and on this trip from Seaham in north-east England was carrying coal to Portsmouth, believed destination Spithead.

She was not the only vessel to get into trouble on that fateful night – three others at least were also to join the list of wrecks on this section of the east coast. One was the Annie Florence, another was the Olive Branch as well as the Nixie, and probably more.

All three of these shipwrecks are referred to under the Board of Trade report of the inquiry for the Olive Branch 1894. (1) The inquiry was held at The New Inn, Saltfleet, Lincolnshire, on Dec 5th 1893.

The Nixie is the first ship referred to in the report. She caused the Donna Nook lifeboat to be out of service to others that fateful day.

The Olive Branch was a wooden sailing ship built in Peterhead, Scotland in the 1870s, being referred to as a barkentine. (2) She had set sail from Teignmouth, Devon, destined for Newcastle-upon-Tyne carrying a cargo of pipe clay.

From reading the inquiry notes, it states the survivors of the Annie Florence were landed. Sadly there was one survivor of the Olive Branch – a Mr Robert Rattenbury. It appears that the Olive Branch was the worst wreck that night.

It was a terrible night with numerous wrecks across the country. There were 59 wrecks that night of 18-19 November around the coast of England, only one of which has ever been found since. (3) There were many worse nights but it was a pretty bad one by any standards.

Serena writes again:

Thank you very much, Jordan, for this blog and all your research! We would like to send our best wishes to all our readers and contributors and all involved in maritime archaeology for Christmas and the New Year, and look forward to welcoming you back in 2018.

For a seasonal gallery which gives an idea of what the Olive Branch looked like, why not take a look at one of the most famous barquentines of all time, the Endurance being crushed in the ice of the Weddell Sea?

Sailor stories

This week I am delighted to introduce my guest bloggers Roshni Hirani, Endeavour Community Participation Producer, and Kris Martin, Exhibitions Interpretation Curator at the National Maritime Museum, Greenwich. Here they give us an exclusive insight into the work that has gone into selecting objects from the London, a designated wreck which sank in 1665. Thank you both for showing how the story of the London continues!

Sailor Stories: a National Maritime Museum co-curation project themed around the wreck of the London

2018 is an exciting year for the National Maritime Museum in Greenwich. In the autumn we will open our new Exploration Wing, a Heritage Lottery funded project consisting of four new permanent galleries which will bring the theme of exploration alive for people of all ages. One of these new galleries will be Tudor and Stuart Seafarers, which will tell a compelling story of exploration, encounter, adventure, power, wealth and conflict during the 16th and 17th centuries. Among the 100 objects from the Museum’s collection, we are delighted to be displaying a small assemblage of artefacts recently recovered from the wreck of the Stuart warship London which sank in the Thames estuary in 1665.

While the Museum has a rich and significant collection of objects from this period, one of the challenges we identified from an early stage was how to represent the lives of ordinary sailors in the Tudor and Stuart navies in the gallery. Members of the project team were already avidly following the progress of the excavation of the London wreck and were fascinated by finds that were being brought to the surface by Steve Ellis and his team. With this in mind, in 2016 we approached Historic England and Southend Museums, the receiving custodian of the excavated material, about the possibility of collaborating on a co-curation project themed around the London, with the outcome being the selection and display of 5 or 6 objects from the wreck in our new gallery.

We were aware of the importance of the London to the Southend community and from the outset, wanted to work with them to help us explore, select and interpret objects from their ‘local wreck’. Through Southend Museums we approached Jessica Russell, Community Outreach, and Patricia North, Head of Art, at Southend Adult Community College and invited them to take part in our Sailor Stories co-curation project. The response from their students was fantastic: 12 adult learners, with different skills, abilities and backgrounds, but with a common interest in heritage and the London wreck, signed up to take part. Encouragingly most of the group stayed with us until the end of the project and we were also delighted to later welcome 2 A-Level students interested in history and museums from nearby Chase High School.

Historic England’s involvement in the excavation, temporary storage and conservation of the London finds meant that it was wonderful that the team at Fort Cumberland, with HE Archaeological Conservator Angela Middleton leading, agreed to come on board as a project partner. A fruitful kick-off meeting there between Southend Museums, Southend Adult Community College, Historic England and the National Maritime Museum laid the foundations for a rich and varied 5-week programme at various sites over the summer of 2017.

The Mary Rose Museum in Portsmouth was the destination for our first Sailor Stories session. Here, Mary Kinoulty, Head of Learning, and Curator and diver Chris Dobbs introduced the Mary Rose, the museum and its new displays. This was the ideal place to give the group a taster of the processes, techniques, challenges and opportunities associated with the selection, interpretation and display of shipwreck material. Moreover this was a chance to enthuse and engage the Southend team with the subject matter and encourage further participation through a well-known wreck and the spectacular interactive displays at the museum.

The second session took place at the National Maritime Museum where our co-curators learnt about the museum, its collection and displays, and the planned new galleries. They were given time to explore the museum with Curator Aaron Jaffer, and together considered the different ways objects can be displayed and interpreted. We introduced the London through an original drawing of the ship by Willem van de Velde, the Elder, in the museum’s collection and looked at ships of the time through paintings and models in the company of Nick Ball, the Museum’s Assistant Curator of Ship Models.

The following week at Southend Museum’s store, participants went ‘behind the scenes’ for a session that considered the excavation, storage, handling and conservation of wreck material. Led by Conservator Claire Reed and Curator Ciara Phipps, this included a hands-on session where the team relished the opportunity to work in small groups to assess and repack waterlogged organic objects excavated from the local area.

Back in Portsmouth for the fourth session, we joined Angela Middleton and the Archaeological Conservation team at Fort Cumberland. This was the first opportunity for the group to see actual objects from the London wreck. As the objects were at various stages of conservation, the participants gained an understanding of the processes and challenges involved, and learnt more about what the work at Fort Cumberland is revealing about the objects and the London.

The group was then split into two and was presented with a preselected assemblage of 25 London objects, taken from over 750 that had been recovered. Without any interpretation they looked at the objects closely thinking about what they could have been used for, what they were made from, what questions they would want to ask about them and what they could tell us, before presenting to the other group a selection of five objects that they would initially pick for public display. After learning more about each object, participants created their ‘final’ selection which had invariably changed from their first choice. Choosing the final selection was challenging given the short amount of time and it was important for participants to have some time to reflect on their choice.

For the final session all participants returned to the National Maritime Museum where the four new galleries will open next year. This session concentrated on museum audiences and interpretation. We asked participants to write their own museum label about something that belonged to them or a piece of clothing they were wearing. They learnt about the importance of ordering information and the difficult decision-making involved in choosing material relevant to their target audience. These were then discussed as a group. The session ended with a review of the London artefacts selected, which includes a leather shoe, a clay pipe, a pewter pot and a broken candle, and a discussion of how they would be interpreted at the National Maritime Museum. We then celebrated the success of the project with a preview of our brand new temporary exhibition, and tea and cake!

The Sailor Stories co-curation project was a great triumph and a mutually enriching and inspiring experience for all involved. Feedback from the participants was universally positive: the group enjoyed ‘seeing and handling artefacts – feeling involved and working in a group’ and ‘meeting the team behind the scenes’. They also loved seeing how museums work, engaging with heritage and conservation professionals and creatively contributing and responding to the project. Southend Adult Community College has produced a short film to commemorate their experience:


(This video has no voiceover)

it appears that the project has inspired at least one participant to seriously consider a career in museums or heritage. The experience opened our eyes to the different perspectives, discussions and debates surrounding the wreck and how members of Southend’s community felt it should be displayed and represented in a national museum. This co-curation model is one that we are keen to follow in future gallery development. We look forward to seeing the outcome of Sailor Stories on display next year.

We would like to thank everyone from Southend Adult Community College, Chase High School, Southend Museums, Historic England, the Mary Rose Trust and Royal Museums Greenwich who took part in the Sailor Stories co-curation project.

Diary of the War: November 1917

SS Belém

I am pleased to welcome as my guest blogger for this month my colleague Stuart Churchley, Marine Planning Archaeological Officer at Historic England. Although this month’s wreck was not lost to war causes, she nevertheless illustrates a little-known aspect of the First World War in the English-speaking world, that of Portugal’s involvement in the war. Stuart writes:

The name of a wrecked vessel can often hold clues not only to its origin, but also the historical context in which it served: today’s wreck, lost 100 years ago on 20th November 1917, is just such a wreck with the potential for a far larger story.

At around the same time as the British Army famously used their tanks on the western front at Cambrai on 20th November 1917, a little-known merchant vessel, the SS Belém, was wrecked at Menachurch Point, just north of Northcott Mouth, Bude.

When I first started researching the SS Belém, my first thought was that this vessel must have been inadvertently lost: an isolated wrecking case on the very periphery of the war action, participating in no known convoy for the area, miscalculating a notorious stretch of coastline like so many others had previously, whilst avoiding the threats of unrestricted U-boat attacks and mines alike.

Locally it is well known and has captured the imagination of visitors and artists, becoming a recognisable feature of the landscape. The wreck itself was photographed at the time of its loss oriented facing south, running parallel to the coastline overlooking to the east.

A brilliant eyewitness account of the ship’s stranding from the perspective of Arthur Madge, can be found within an online pdf produced by a local historian, Audrey Aylmer, which also includes photographs of the site in 1997, 80 years after the Belém came ashore. (1) As an eight year old boy in 1917, Arthur had been awoken at his boarding school by the sound of the distress signals in fog from the stranded Belém (so she had certainly not been lost to war causes).

Today, when tides and wind work in tandem, a mixture of metal features can be revealed on the beach. It’s easy to see that the coastline of shale and sandstone known as the ‘Bude Formation’ and heavy westerly winds has caused the ship to become severely disarticulated, mangled and a little bit hazardous underfoot. The intertidal sand has formed a protective layer over what remains of the wreck, comprising a long subtly curved hull structure, a boiler cracked open like a an eggshell, large elements with rivet patterns and flanges, and the propeller itself sitting serenely within a bowl of scoured sand. The site is very clearly seen from above by drone in some excellent 2015 images published by Martin Busby online. (2)

Tracing back why a vessel owned by the Portuguese government came to be here is not easy. However, looking at the wider historical background can be a fruitful and interesting undertaking.

Portugal was pretty much neutral for the first half of the war, but was faced with a challenging period due to the limiting – and almost total loss – of trade with its pre-war European neighbours to the Atlantic north and within the Mediterranean. As relations gradually soured, Imperial Germany declared war on Portugal on 9th March 1916, as a result of a multitude of factors, most notably the capture and confiscation on 23rd February 1916 of the 72 German ships interned in Portuguese ports on or since the outbreak of war. (3)

These seized vessels comprised roughly 10% of all German vessels holding out in neutral ports at this time, and equated to a tonnage double the Portuguese merchant navy before the war. (4) Such a scenario therefore would have proved tempting to both the Portuguese and British authorities, during an ever-growing shipping crisis, with the potential for some form of agreement along the lines of those made with other nations as the ripples of the war spread ever outwards. (5)

What is all the more interesting is that the British had made just such a secret agreement with the Portuguese high command in Belém Palace, Lisbon, on 5th February 1916, leading up to the capture of the 23rd. In doing so the captured vessels would be divided between Britain and Portugal, with 80% of these ships sent to British war effort, and 20% being retained by the Portuguese. (6) (In previous posts we have looked at the fate of interned German vessels in British service; German shipping company property in England, and the secret Tonnage Agreements with Scandinavian countries.)

This decision to seize the German ships in Lisbon would also have far-reaching consequences for Portugal, with the German Navy laying mines in and around the mouth of the Tagus, and the subsequent arrangements for the Portuguese army to be transported to Brest, whence they would advance to the Flanders fields to support the British army. (7)

Could it then be that the SS Belém was one of the 14 vessels transferred to Portugal out of the original 72 internees?

To know this conclusively would take much greater research than has been undertaken here, but from what we know about the Belém, it would seem likely that she was one of that group. Previously named Rhodos, the ship was built in Flensburg in 1890 by Flensburger Schiffsbau Gesellschaft. The Rhodos was possibly very familiar with Portuguese ports, given her original owner, the Deutsche Levante Linie A.G.

However, records document that she came into the ownership of the Transportes Maritimos Do Estado (Portuguese State Steamship Line), in 1916, consistent with the events leading up to the famous prize capture, while other vessels similarly seized by Portugal are known to have ended up in the same ownership, suggesting that the company was formed to account for these ships. (8)

This certainly tallies with the source from Audrey Aylmer which details that the Rhodos, which she suggests was seized in Lisbon in 1916, and later loaned to Italy to bring coal from England, while her return cargo would generally be sulphur from Sicily to England for munitions. In other words, she would work a reasonably familiar route.

Furthermore Audrey Aylmer’s narrativegoes on to say that there was no sulphur ready on the Belém’s final voyage so the vessel came back to Benjaffa, Oran, North Africa, to load 2500 tons of iron ore for Cardiff.

After she was wrecked, holes were cut in her sides to throw out the cargo, and the swell caused large holes in the ballast tanks. The Belém is believed to have been later sold to the shipbreakers, with what remained of the cargo salvaged. (9) This would suggest that the remains represent possibly a combination of natural and human factors, but are no less fascinating for that.

The Belém is a rare archaeological witness in English waters to this pivotal event in Portugal’s involvement in the First World War. Strangely, there is another not far away, another ship also belonging to the Transportes Maritimos do Estados, the Brava (ex-German Togo) torpedoed off Trevose Head in 1918, while inbound to Cardiff with pit props.

What became of some of the other 71 vessels is unclear: many are thought to have been destroyed by German submarines in route to British ports, certainly the fate of Tungue (ex German Zieten), which was torpedoed by UB-51, another Transportes Maritimos do Estado vessel, which was chartered by Britain on her final voyage.  (10) Given the Belém‘s destination of Cardiff with iron ore, chartering to Britain might well explain why she was said to have had two Royal Navy gunners aboard, who were rescued along with the other crew. (11)

However, it has been pointed out that one of the minor successes of this decision to bring about formal entry into the conflict was the agreed return of the surviving captured German ships from Britain and France, which would form the basis of Portugal’s post-war merchant fleet in the 1920s. (12) The Belém is an excellent illustration of how profoundly the First World War changed shipping around the globe, and with what long-term effects.
