On 26 September 1918 the U.S. Coast Guard Cutter Tampa (operating as the USS Tampa under wartime rules) was lost with all hands, a total of 131 men. This was the greatest combat loss taken by the U.S. naval forces during World War I as well as the greatest loss of life incurred by the U.S. Coast Guard in its entire history.
The Tampa's short story began on 9 August 1912 when the U.S. Revenue Service Cutter (UCRC) Miami, built by the Newport News Shipbuilding and Drydock Corp., was commissioned at Arundel Cove, MD. The ship was named for the Miami Indian tribe rather than for the then little settlement in south Florida. At the time, several revenue cutters were named after Indian tribes. The Miami was 190 ft. long, with a 14.6-ft. draft and a displacement of 1,181 tons. Her normal crew complement was 70 officers and men, she carried three quick-firing six-pounders and various small arms, and she could do 13 knots.
The Miami's first duty was with the International Ice Patrol, operating out of Halifax and looking for icebergs. Subsequently she was based at Tampa, Florida, and developed a relationship with the city.
In January 1915 the Revenue Cutter Service and the Life-saving Service were merged and re-named the U.S. Coast Guard. It was then decided that the Indian tribal names were to be phased out, so in February, 1916 the Miami was renamed the U.S. Coast Guard Cutter (USCGC) Tampa.
Soon after war was declared on 6 April 1917, according to law the U.S. Coast Guard was transferred to the U.S. Navy for the duration of the war. Three days later, the USS Tampa, along with the former USCGC Tallapoosa, seized the Austrian merchant ship Borneo, the first overt action by Coast Guard ships in the war.
At the time the USCG had 23 cutters capable of ocean service, which were sent to east coast Navy yards where they were up-gunned and outfitted with depth charges. In August and September 1917 the cutters Ossipee, Seneca, Yamacraw, Algonquin, Manning, and Tampa left for European service. They were designated as Squadron 2, Division 6 of the Atlantic Fleet's patrol forces (the flagship was the slightly larger gunboat USS Paducah PG-18), and the squadron was based at Gibraltar. These cutters escorted hundreds of vessels convoying between Gibraltar and UK and also performed escort and patrol duty in the Mediterranean.
On the evening of her loss, USS Tampa was detached from escorting Convoy HG-107 in the Bristol Channel with orders to proceed to Milford Haven, Wales, to discharge passengers. At 8:45 p.m. an explosion was noted by a hydrophone operator in the convoy. Subsequently the Tampa failed to arrive at her destination and a search was made for her by U.S. and British patrol craft. A small amount of wreckage identified as belonging to the Tampa and two unidentified bodies in naval uniforms were found. Two other bodies later washed ashore. Losses were 111 U.S. Coast Guard, four U.S. Navy, eleven Royal Navy, and six civilians.
The British Admiralty notified Rear Admiral William Sims, USN, commander of the U.S. Navy in Europe:
Their Lordships desire me to express their deep regret at the loss of the U.S.S. Tampa. Her record since she has been employed in European waters as an escort to convoys has been remarkable. She has acted in the capacity of ocean escort to no less than 18 convoys from Gibraltar comprising 350 vessels, with a loss of only 2 ships through enemy action. The commanders of the convoys have recognized the ability with which the Tampa carried out the duties of ocean escort. Appreciation of the good work done by the U.S.S. Tampa may be some consolation to those bereft and Their Lordships would be glad if this could be conveyed to those concerned.
The German U-boat UB-91 claimed credit for sinking the Tampa. Her captain, Kapitänleutnant Wolf Hans Hertwig, wrote in his service log that he had spotted the Tampa while he was running on the surface and submerged and fired the torpedo from the stern tube at a distance of 550 meters, which hit the Tampa amidships.
Hertwig was a very new U-boat commander in a new craft; the UB-91 had been commissioned in April. He had spent nearly all of the war with the High Seas Fleet, having served at the Battle of Jutland on SMS Westfalen, had only recently graduated from the U-boat training program, and his first patrol had no results. How did an inexperienced U-boat commander and crew pull off a tricky stern shot at very close range so flawlessly? In any event, the official U.S. Coast Guard history doesn't concede that UB-91 sank the Tampa.
The men of the USS Tampa are commemorated at the Brookwood ABMC Cemetery and Memorial in Surrey, UK, and also on the U.S. Coast Guard memorial in Arlington National Cemetery.
