Operational history
U-199 sailed from Kiel on 13 May 1943 on her first and only operational patrol; she negotiated the gap between Iceland and the Faroe Islands, before heading south and had crossed the Equator by 17 June, targeting ships in the South Atlantic Ocean. Operating off the Brazilian coast, she torpedoed and damaged the Brazilian armed merchant shipBury, which returned fire and managed to escape. On 4 July, the submarine was spotted on the surface by the small fishing boat Changri-Lá. The Brazilian boat was sunk with the loss of all hands by gun fire. U-199 had her first and only significant success, sinking the British merchant shipHenzada on 25 July.
Fate
U-199 was found on the surface, off Rio de Janeiro, in position, by three aircraft, a PBY Catalina and a Lockheed Hudson and an American PBM Mariner of VP-74 on 31 July. The Catalina, codenamed Arará, hit U-199 with depth charges, sinking her. The pilot of the Catalina was 2º Ten.-Av. Alberto M. Torres, which later went to Italy as part of 1st Brazilian Fighter Squadron. Forty-nine of the crew were killed, although twelve Germans managed to escape the doomed submarine, including the captain. This was possible due to the actions of the Catalina’s crew, who threw a lifeboat to the survivors. They were rescued by the and taken to Brazil, and then on to captivity in the United States.
