The TAMPA was one of six Coast Guard cutters on convoy duty in World War I escorting ships between Gibraltar and Pembrokeshire ports. On 26 September 1918 she was sunk by a torpedo from UB 91 off the coast of Cornwall. All hands were lost, including 111 US coastguards, 4 US Navy sailors, 10 Royal Navy sailors, and 5 British civilian dockyard workers. The total loss of life was 131. It was the single largest loss of life the US Navy suffered during the First World War. A memorial mural was dedicated in Tampa, Florida, in February 2018.
This tribute was suggested by David Swiddenbank and Ceri Joseph. In association with Porthcawl Museum.
