Addy, Theodore Thomas, TM2c

Commissioned into service in the summer of 1943, USS Dorado conducted shakedown and training operations off the New England region of northeastern United States. On 6 Oct 1943, she departed for the Panama Canal Zone for the ultimate destination of Pearl Harbor, US Territory of Hawaii. On 12 Oct 1943, a US Navy PBM Mariner aircraft operating out of Guantánamo Bay, Cuba detected an unidentified submarine and attacked her with three depth charges and one bomb; it was not clear whether the submarine was damaged; later in the patrol, the same aircraft encountered another submarine which fired on the aircraft. Later, an Allied convoy sailing through the region reported no contact with any friendly submarines. After Dorado had failed to arrive at the Panama Canal Zone on 14 Oct, air searches were launched, finding scattered oil slicks that later investigation found to be not of submarine fuel in nature. It was ultimately concluded that both of the submarine contacts that the US Navy PBM Mariner aircraft encountered on 12 Oct 1943 were indeed hostile (the second contact was later concluded to be German submarine U-214), and thus USS Dorado was most likely lost due to an accident or to a German naval mine.
 
TM2 Addy was among the crew listed as missing in action and later declared dead.
