Navy Divers Train In The River Thames -- Two Naval divers and a frogman dive in the river Thames off Lambeth Pier, as a part of their training this morning. For the first time Royal Navy divers were today engaged in training exercises under the River Thames. These exercises took place in the murky waters of the River bed from below the Pool of London to Battersea. The divers operated from the anti-submarine and minesweeping trawlers H.M.S. Annet, and H.M.S. Flatholm (both 560 tons) below the Pool of London and, above Tower Bridge to Battersea from specially fitted motor cutters. January 28, 1954. (Photo by Fox Photos).
