Wessex Archaeology has three newly qualified commercial divers. The trio, Nic Bigourdan, Andrea Hamel and Kevin Stratford – all Archaeologists in our Coastal and Marine team - have spent five weeks at Fort Williams’s Underwater Centre in Scotland training for their HSE Surface Supplied commercial diving qualification. Although we have supported several staff carrying out such training in previous years, this is the first time that Wessex Archaeology has fully funded the commercial course.

Wessex Archaeology has been a registered commercial diving contractor since 1996 and is a full member of the Association of Diving Contractors. Our diving team includes two supervisors, one of whom is also qualified as a Diver Medic.

Equipped with surface-supplied equipment, digital video and acoustic tracking, WA carries out many forms of archaeological diving work. Investigations range from detailed surveys of historic shipwrecks for government heritage agencies, to checking suspected archaeological sites amongst anomalies identified by marine developers.

EPPIC Placements Underway

Stuart ChurchleyTwo one-year professional work placements at Wessex Archaeology’s coastal and marine section are currently underway. One post, for a marine geophysicist, was filled by Patrick Dresch. Patrick, who did his initial BA in anthropology at Kenyon College, Ohio, recently completed a masters in maritime archaeology at Southampton University after several years working as a field archaeologist.

The other post, for a coastal and marine archaeologist, was taken by Stuart Churchley. He was awarded his BSc in maritime archaeology by Bournemouth University, followed by two years gaining experience working on the Newport Ship in Gwent, helping with ship model reconstruction and conservation.

The placements are funded by English Heritage and administered by the IfA. They are designed to allow Patrick and Stuart to develop their skills while working on a range of strategic and development-led projects. So far Patrick has been learning about marine geophysical processing and has also spent a week in Ilminster on a land-based  geophysical survey. He found what appear to be anti-tank traps dating to World War II.

Stuart has also been experiencing marine geophysical survey during the investigation of several protected wreck sites off Kent. During his placement he’s also been helping with the presentation of outreach projects at large public events and was recently involved in testing seabed sampling methods in order to better understand submerged Palaeolithic landscapes in the southern North Sea.

Key Discovery Scoops Top Award

The discovery of the Stone Age Hand axes from the North Sea was awarded the Best Discovery Award in the prestigious British Archaeological Awards held at the British Museum on Monday.

The hand axes, described by Phil Harding as ‘massively important’, date back tens of thousands of years. They were used by Stone Age hunters at a time in the Ice Age when water was locked up in the ice caps and the North Sea was dry land. The axes were found in gravel that was dredged from the seabed near Yarmouth but landed in Holland.

Their discovery gives decisive proof for a submerged landscape that experts thought had been destroyed. It was thought that rising sea levels had swept away all traces of this Ice Age world. The discovery of the hand axes, announced earlier this year, surprised the experts and caught the public imagination around the world.

The international collaboration that ensured the axes were reported was acknowledged by the judges who awarded the prize jointly to Jan Meeulmeister, the amateur archaeologist and fossil hunter who identified the finds; the British Marine Aggregates Producers Association who run the scheme for reporting archaeological remains found in dredging for sand and gravel at sea; and Hanson Marine Aggregates Ltd who promptly stopped dredging in the area the finds came from. The judges also praised the collaboration between the Dutch and English government archaeology services.

Awarding the prize Alison Taylor said ‘The find was reported across the world on TV, radio and in newspapers, while the thousands of online hits demonstrate that this find really engaged with the public’s fascination with archaeology. Overall this was, and continues to be, an excellent archaeological project.’

Dr Antony Firth of Wessex Archaeology who run the reporting scheme for the British Marine Aggregates Association and who nominated the find commented ‘This award is thoroughly deserved. It recognises the vision of the industry in introducing and supporting this voluntary scheme. Having the scheme in place meant that the significance of the hand axes was recognised and action was taken internationally and promptly. As a result a find of crucial importance was saved.’

SS Mendi report online

ss Mendi Geophysical Assessment

Multibeam bathymetry of the Mendi

Wessex Archaeology has just processed and interpreted sidescan and multibeam data from the wreck of the troopship Mendi, which sank with the loss of 649 lives after a collision off the Isle of Wight on 21 February 1917. The project was jointly funded by the South African Heritage Resources Agency (SAHRA) and English Heritage.

Geophysical Survey of the Mendi

During the summer of 2007 a Regional Environmental Characterisation (REC) survey was conducted along the south coast of the United Kingdom as part of the Department of the Environment, Food and Rural Affairs’ (DEFRA) Marine Environment Protection Fund (MEPF) programme of regional seabed mapping.

One of the planned survey lines was to pass within a mile or two of the Mendi, and at the request of Wessex Archaeology and English Heritage the REC Steering Group agreed to an adjustment of the line to allow the collection of data over the site of the wreck.

What the Data Shows

The geophysical data shows the wreck oriented approximately east to west – with the bow in the west and the stern in the east. The hull appears fairly coherent, but with a chaotic internal structure and some outlying deSidescan sonar image of the Mendibris. Most of the collapsed wreckage from the superstructure seems to be concentrated within the hull. This confirms diver descriptions which indicate that with the exception of the bow and stern, the wreck has collapsed in many areas. Within the general collapse, the bow and stern remain relatively intact, as does the amidships section where the boilers and engine are clearly visible in the data.

The bow appears to have broken away from the rest of the wreck and a large amount of scattered debris is present in this area. This may be the mark of the fatal damage suffered when the Mendi was rammed by the Darro. The break is in the area where survivors’ accounts describe the bow of the Darro cutting deeply into the Mendi‘s hull – to within a couple of feet of her midline.

What the geophysical data also appears to show is that when compared to diver reports about the condition of the wreck, the bow and stern have seen a marked deterioration in last 3-5 years, and this may be indicative of a more general, rapid degradation of the wreck as a whole.

Previous Work

The geophysical assessment builds on previous work conducted by Wessex Archaeology in 2007. To coincide with the 90th anniversary year of the sinking of the Mendi, funding was provided by English Heritage to undertake a desk-based appraisal of the wreck and its story.

This appraisal drew together a huge amount of information about the events surrounding the loss of the ship. It gathered, for the first time, available information about the wreck itself, and allowed us to start creating a picture of the wreck site – its layout, condition and state of preservation. Perhaps most importantly, the desk-based work showed that the wreck of the Mendi is an important physical focus for investigating a little known and largely forgotten aspect of World War I history – the story of the British and Foreign Labour Corps. Of the men who died when the Mendi sank, most were non-combatant black South African labourers, en route to France to support British operations on the Western Front.

Future Surveys

The recent geophysical assessment has identified a range of target areas for investigation during a Remotely Operated Vehicle (ROV) survey that Wessex Archaeology hopes to carry out on the wreck in the near future.

We would like to gather better evidence of the condition and relative stability of the wreck, the possible impacts of human intervention on the site since its discovery, and the information relevant to its future survival. We’re also interested in a non-intrusive investigation of the artefacts that survive on the wreck which speak for the presence of more than 800 South African servicemen on the Mendi when she sank.

Podcast: Aircraft Crash Sites at Sea (part two)

The following podcast relates to the ALSF funded Aircraft Crash Sites at Sea: A Scoping Study project undertaken by Wessex Archaeology in late 2007. The project is looking at what information is available about civilian and military crash sites around the UK.

In this, the second podcast relating to the Aircraft Crash Sites at Sea project the author of the report, Graham Scott, discusses the importance of these sites and some case studies of actual UK marine crash sites and what these tell us about the types of sites are on the seabed and their importance for aviation archaeology and management of aggregate dredging licences.

Podcast: Aircraft Crash Sites at Sea (part one)

The following podcast relates to the ALSF Funded Aircraft Crash Sites at Sea: A Scoping Study project undertaken by Wessex Archaeology in late 2007. The project is looking at what information is available about civilian and military crash sites around the UK.

In this podcast you will hear the Project Manager, Euan McNeill, discussing the origins of the project, through material found by aggregate dredging and reported through the English Heritage and British Marine Aggregate Producers Association Protocol for Reporting Finds of Archaeological Interest.

Euan discusses the origin of the protocol and the ongoing Implementation Service which is operated by Wessex Archaeology and administers the scheme. He also discusses the role the aggregate industry is playing in bringing to light archaeological finds, and pieces of aircraft in particular, and what impact this has on aggregate dredging.

Wrecks on the Seabed: Ecology

Ever wondered about the plants and animals that live on shipwrecks? What sorts of effects do these critters have on archaeological remains? Can the types of flora and fauna that chose to colonise a particular wreck tell us anything about the stability of the site, for example?

Condenser Resident

These are some of the questions that Wessex Archaeology hopes to answer in the exciting new ‘Wrecks: Ecology’ project.

The project will investigate whether archaeological information from wrecks can also provide information about the plants and animals that inhabit them, and from this, say something about the environmental processes at work off the East Sussex coast.

Understanding the ecology of wrecks will improve the management, conservation and monitoring of these heritage sites. It will also improve archaeologists’ ability, when considering seabed developments, to better assess their potential positive and negative impacts on historical wrecks.

The ‘Wrecks: Ecology’ project is funded by the Aggregate Levy Sustainability Fund (ALSF) through English Heritage.

HMS Drake, Rathlin Island

HMS Drake was built at HM Dockyard at Pembroke, between 1899 and 1902. HMS Drake was a Drake Class armoured cruiser, based on the Cressy Class cruisers. Cruisers were a class of warship developed in the 19th century designed for scouting, commerce warfare and showing the flag, roles previously taken by frigates, corvettes and sloops. Although cruisers could be powerful ships (HMS Drake was a 14,000 ton vessel capable of 21-23 knots) cruisers were not intended for duty in the battlefleet.

The construction of HMS Drake did not run entirely smoothly. Captain John Jellicoe commanded the ship while it was fitted out, and letters from him to the Captain Superintendent of the dockyard describe his concerns about doors not closing below decks and numerous leaks. In one passage Jellicoe mentioned how his description of the problems with the ship to the Commander in Chief made “… his hair stand on end”.

HMS Drake was finally completed in 1902, and following trials and home duties it was finally commissioned by the King at Portsmouth in March 1905. It then travelled to various destinations in the Mediterranean and elsewhere for ceremonial duties, receiving the Kings and Queens of Spain, Portugal and Greece, and it also hosted a ball by Prince Louis in New York.

HMS Drake was variously the Flagship of the 2nd Cruiser Squadron of the Atlantic Fleet, then the Flagship of the 1st Cruiser Squadron, before being transferred to the 5th Cruiser Squadron, Home Fleet. By 1913 HMS Drake was nearly a decade old, which during this period of rapid naval development made her as good as obselete, and so the cruiser was reduced and placed on the reserve list.

The outbreak of World War One however, put so much pressure on the Royal Navy for capital vessels that HMS Drake was recommissioned in 1914, just in time for test mobilisation and the Fleet Review. HMS Drake was given escort duties and its first escort run was taking the Olympic, sister ship of the Titanic into Liverpool after the Olympic had travelled from New York.

HMS Drake joined the 6th Cruiser Squadron of the Grand Fleet in 1915, and was refitted in October. from 1916 the ship continued its escort duties but it still required another refit. A major design flaw of the Drake Class cruisers were their 6-inch lower casement guns. The guns were so low on the side of the vessels that they could only be fired in the calmest sea conditions. The 1916 refit removed the lower 6-inch guns, and replaced them with four 6-inch guns in shields on the shelter deck, port and starboard.

On October 2nd 1917 HMS Drake had just finished escort duties for convoy HH24 from America, near Rathlin Island off the north coast of Ireland. The convoy dispersed at 08.03 am , but just over an hour later HMS Drake was torpedoed under the second funnel by U-79 under the command of Lieutenant Commander Otto Rohrbeck. The U boat was on patrol in the area and had laid a string of 11 mines between Rathlin Island and the mainland only a few days before.

HMS Drake’s Captain, Captain Radcliffe, reported that the torpedo hit the ship by the number two boiler room on the starboard side. The boiler room was instantly flooded, killing everyone there except one man who was blown onto the upper deck and landed there unhurt, and another who climbed up through the stokehold hatch. The crew man who was fortunate to be blown unhurt from the boiler room, immediately reported for duty in the number three boiler room where he remained until the ship was abandoned.

From surviving naval records, details of the last hours of the cruiser can be pieced together. We know Captain Radcliffe initially thought he might be able to take the stricken vessel into Belfast where the ship could be repaired at the Harland and Wolff Shipyards, but after a discussion with his engineer, he realised that this was impossible, so he decided instead to make for the nearest anchorage at Church Bay, Rathlin Island.

HMS Drake had lost the use of its steam steering gear in the attack and had to try to steer using only propellers, until this could be repaired. With such limited manoeuvrability however, HMS Drake collided with the cargo ship Mendip Range at 10.37 am. HMS Drake it seems did not receive much damage from the collision, but the Mendip Range was forced to beach at Ballycastle Bay on the mainland.

HMS Drake and the Mendip Range were not the only casualties of the day, at 11.30 am HMS Brisk, one of the escorting destroyers of the convoy was either torpedoed by U-79, or more likely struck one of the U boat’s recently laid mines. Another ship from the convoy, the Lugano, also sank at around this time, probably after hitting another mine.

HMS Drake managed to anchor in Church Bay by 11.46am. Most of the men on board were taken off by launched from the destroyers and sloops that were laying a submarine screen around the ship. Captain Radcliffe now hoped to keep the ship afloat until salvage vessels could arrive, but the list of the ship continued to increase. At this point HMS Martin and HMS Delphinium then came alongside to remove the remaining crew. Captain Radcliffe wrote of HMS Drake’s final hours that ‘Nobody but the dead remained on board the Drake when I left her for HMS Delphinium, the mess decks, boiler rooms, Engine room had all been searched and reported clear. Ship was abandoned at 2.05 pm.”

Captain Radcliffe ordered HMS Delphinium to anchor close to HMS Drake, so he could go back aboard when the salvage vessels arrived, but the ship continued to list and finally capsized at 2.35 pm with part of its port side out of the water.

Salvage of the wreck began in the 1920s and continued sporadically over the years. In 1962 a Fleetwood steam trawler the Ella Hewett, en route for the cod fishing grounds off Iceland collided with the remains of HMS Drake and sank on top of it. Then in the 1970s divers from the Scottish and Northern Ireland Bomb and Mine Disposal Team started clearance operations on HMS Drake. When the clearance operation was completed, both the remains of HMS Drake and the Ella Hewett were ringed with depth charges. These were exploded with the intention of blowing down the upstanding parts of both wrecks, to reduce the possibility of more vessels running aground on them. By 1978 fuel oil was leaking out of the vessels causing pollution problems in Church Bay, so another salvage operation was made to remove the remaining fuel oil from the wrecks.

HMS Drake is now one of the most popular dive sites in Northern Ireland, thanks to its relatively shallow depth of less than 20 metres and the good visibility in the waters of Church Bay.

Wessex Archaeology’s Diving Investigations

In 2006 Wessex Archaeology was asked to carry out an undesignated site assessment of HMS Drake for the Environment and Heritage Service of Northern Ireland. The undesignated survey was intended to examine the condition of the wreck, assess if it was under threats in any way and see whether the wreck was a good candidate for protection under the Protection of Wrecks Act 1973.

Before diving fieldwork in the summer of 2006, Wessex Archaeology staff sought out records relating to the loss of HMS Drake and found detailed records of the court martial that followed the loss of the ship in the Public Records Office at Kew and letters and documents relating to its construction at the at the National Maritime Museum, Greenwich. The examination of the records raised an important question about the wreck. Captain Radcliffe’s report on the sinking makes it clear that 18 men died in the torpedo attack and were left on the ship when he abandoned it, but dive guides to the wreck say that the bodies were removed although none give any reference to when this occurred. To date Wessex Archaeology has not found any record of the bodies being removed. The final resting place of the 18 crew is still unclear.

Wessex Archaeology divers visited the wreck in July and August 2006. Despite the obvious damage done to HMS Drake by the torpedo attack and the blasting of the ship with depth charges in the 1970s, the wreck is still in a reasonable condition and our divers were able to identify many different features on the wreck.

The distinctive ram bow of HMS Drake is still visible, although the hull plating has come off it in places, and attached to the bow is a paravane skeg, an attachment fitted to many ships to allow them to drag mine sweeping wires from their bows. Just south of the surviving bow structure, the divers found the remains of the Ella Hewett, heavily broken up, but still lying on HMS Drake on the north east part of the site.

Paravane skeg onthe bow of HMS Drake

Divers also recorded part of a propeller shaft showing signs that the propeller had been blasted off, probably during salvage on the ship. Some remarkable features were found towards the stern of the ship, including the rudder and part of the steering gear, and at the stern a central hawse hole was found along with a large section of the gallery on the stern of the ship. Wessex Archaeology divers also made searches of the seabed around the main wreck to see what kind of material lay away from the main wreck site, and during one of these dives found a large Martin type anchor from HMS Drake.

The stern of HMS Drake

Wessex Archaeology’s assessment of the wreck showed that while HMS Drake is extensively damaged, some parts of the vessel are remarkably intact and recognisable. HMS Drake is clearly an important ship as it represents a period of rapid naval development when vessels often became obsolete very quickly as new designs and advances were made. No cruisers of this period are afloat today, all were either lost in action or scrapped. The HMS Drake is the only vessel of its class easily visited by divers.

While investigating the wreck our divers discerned few obvious threats to the wreck apart from the occasional pilfering of material by irresponsible divers. In some cases this has included ordnance not already salvaged from the site. Due to the absence of major threats to the wreck and its clear popularity among divers, the wreck has not been designated, but instead it is hoped it can be managed with the help of the diving community so that any changes to it are noted and people are made aware of the dangers of the remaining munitions on the site.
