We arrived on our next dive to find most of these items gone, as if they had vanished into thin air. It was a horror to see these precious artefacts disappear before our eyes, but it was also a real privilege to be the first ones to have seen them in over 350 years. It was becoming more likely that no one would ever see them again.
It quickly became clear that the site was severely unstable; as although underwater artefacts are known to disappear in tides or through erosion, it’s not normal for them to vanish in a matter of weeks. Though there are many reasons why this might happen, it’s thought that the recent dredging activity to deepen the channel has had an impact in uncovering the site, exposing it to the mercy of the Thames.
Rescue & Recovery
Thankfully Alison James of Historic England was sympathetic to our concerns. She approached Southend Museum Services, asking them to be the receiving museum for any recoveries from the wreck, and they kindly accepted. This was fantastic news as it meant the artefacts could stay where they belong, in the London’s final resting place of Southend.
To me, the difference between archaeology and salvage is that archaeology is all about recording as much information as possible and learning from it, which is what we set off to do.
Wessex Archaeology and Historic England produced the London Recording Protocol. This meant that we had an agreed approach to record the site, and ensured that everything we did was in-keeping with archaeological best practice.
Historic England then funded further training to recover artefacts deemed at risk, with Angela Middleton, Historic England’s specialist conservator, giving us ‘first aid training’ for the recovered artefacts. She also kindly offered to conserve the finds for us. The team was then granted a Surface Recovery License. We could now save artefacts that would otherwise disappear into the Thames, and continue our mission to learn as much about this wreck before her artefacts are washed away forever.
This was a great experience – not many people could say they were given training by professional archaeologists on how to record and save 350-year-old artefacts from the depths of the Thames Estuary!
After many dives, we were certain that the wreck was suffering from localized erosion. We knew this due to the sheer amount of artefacts that we were recovering from the shifting silt, and from witnessing the currents taking away wooden fragments of the wreck on each tide. Recovering these artefacts allowed me to develop the site plan more with each dive, which was both a blessing and a curse.
The Mary Rose & The Vasa Musuems
There are many parallels between the London and one of the UK’s most well-known conserved shipwrecks; which is of course the Mary Rose.
Ever since I was a child I have had an interest in underwater archaeology – I remember watching Jacques Cousteau on the TV; then in later years, seeing the Mary Rose as she was raised. This explains why I simply couldn’t refuse when Alex Hildred and Chris Dobbs of the Mary Rose Museum invited me to a behind-the scenes tour!
Seeing the results of all their hard work, and learning more about the history of the Mary Rose, made me realise how similar they are in historic importance. I never thought I’d ever have a chance to be a licensee of such a historically significant wreck with a site plan which looked very similar to the Mary Rose!
The team and I later also joined the Nautical Archaeology Society on their annual trip to the Vasa Museum in Stockholm, where Dr Fred Hocker gave us a guided tour. Getting first-hand accounts into the work put into these two famous ships really helped my hypothesis of the wreck of the London, as we were able to visualise many parts of the ship in ‘real terms’. With the Vasa being a contemporary ship to the London in terms of size, structure and date, it was fantastic to see it in all its glory in the museum, and I could imagine the London being similarly displayed for all the world to see.
Cotswold Archeology
Working with Cotswold Archaeology, we put our new HSE diving techniques into practice on the site. I was given the opportunity to choose the positions of where three trenches would be placed. From the creation of these trenches, I was then able to confirm my theory of the layout, which led to the exciting discovery of a complete gun carriage. These are about as rare as hen’s teeth, and so it was recovered to ensure protect it from further erosion or even loss. Seeing this being lifted, knowing that we had saved it from disappearing into the Thames, was a very proud moment for us.
