The remains of a German World War I U boat are visible on a mudflat next to the River Medway in Kent.
The BBC reports that experts believe it is UB122, which was one of more that 100 U boats that surrendered at the end of World War I and were subsequently scrapped by the British.
UB122 was built in Bremen and launched on 4 March 1918. She carried 10 torpedoes and a 8.8cm deck gun. She had a crew of three officers and 31 men
