German submarine U-804 was a Type IXC/41 U-boat of Nazi Germany's Kriegsmarine during World War II. U-804 was ordered on 7 December 1940, and was laid down on 1 December 1942 at Deutsche Schiff- und Maschinenbau AG Seebeckwerft, Bremerhaven as yard number 362. She was launched on 1 April 1943 and commissioned under the command of Oberleutnant zur See der Reserve Herbert Meyer (Crew III/37) on 4 December of that year.[2]

Service Record[edit]

Training[edit]

U-804 began training exercises with the 4th U-boat Flotilla on 4 December 1943, and finished her sea trials on 30 June 1944. On 16 June 1944, U-804 was attacked by a Norwegian Mosquito aircraft from No. 333 Squadron RAF, but succeeded in shooting down its attacker at the cost of eight crew members wounded; only minor damage was inflicted on the submarine. The two-man crew of the Mosquito was picked up by U-1000 on 18 June, and taken to occupied Norway.[2]

First patrol[edit]

U-804 began her first war patrol on 19 June 1944 (while still undergoing training) with the 10th U-boat Flotilla. She left Bergen and headed into the North Sea, passing north of the British Isles into the North Atlantic, where she remained for 116 days. On 2 August, during a special hunt for several submarines known to be transmitting weather information from stations in the central and north Atlantic (of which effort U-804 was a part), two American destroyer escorts, Fiske and Douglas L. Howard, were detached from the task group to investigate the whereabouts of U-804, which both had made contact with. Upon sighting the destroyers, the U-boat quickly dived, but the two escorts detected her on their sonar and began their attack approach. Suddenly, USS Fiske was torpedoed on her starboard side by U-804, and within 10 minutes, she broke in two. Thirty-three of her men were killed and 50 were wounded, but all the survivors were rescued by USS Farquhar. Amidst the confusion following the sinking of USS Fiske, U-804 slipped away and returned to her patrol.[4][5]

Second patrol[edit]

On 12 October 1944, U-804 returned to the port of Flensburg after 116 days at sea. Five days later she left Flensburg for Kiel, where she remained until 4 April 1945 before leaving for occupied Norway. While en route in company with another of the flotilla's boats, U-1065, the two submarines were detected and attacked in the Skagerrak strait on 9 April 1945 by over 30 Mosquito aircraft from three Royal Air Force squadrons based at Banff. U-1065 succeeded in shooting down one of the attacking aircraft before being hit by several rockets fired by 10 Mosquitos from 143 and 235 Squadrons; she exploded and sank with the loss of her crew of 45 men.

Fate[edit]

U-804 suffered the same fate - after being hit by rockets from the attacking Mosquitos she also exploded and sank at 57°58′N 11°15′E / 57.967°N 11.250°E / 57.967; 11.250Coordinates: 57°58′N 11°15′E / 57.967°N 11.250°E / 57.967; 11.250, with no survivors from her crew of 55 men.[2][4][6]
