The largest-ever post-war salvage operation on the Thames has discovered seven shipwrecks up to 350 years old.
They include a warship that was blown up in 1665, a yacht converted to a Second World War gunboat, and a mystery wreck in which divers found a personalised gin bottle.
The vessels, in the Thames Estuary, are just some of about 1,100 ships which went down in the whole of the river.
