Horst Hamm joined the Kriegsmarine in 1935. From August 1939 to May 1940 he served as the Second Watch Officer (2WO) on the U-26 spending 120 days at sea on 4 patrols. From June to Aug 1940 he served with the 1st Flotilla before being sent as First Watch Officer on the famous U-96 in Sept.
With the U-96 Hamm went out on 3 patrols spending 70 days at sea. On his first patrol with this boat they sank 5 ships (37,037 GRT) and damaged 2 more (15,864). The second patrol was also successful but they third patrol saw the boat sink 7 ships with a total of 45,391 GRT.
190 days at sea during 7 patrols on 2 U-boats under very competent Commanders gave Oblt. Horst Hamm invaluable experience for his own command. He got his own boat on 7 April 1941 when he took command of the small school boat U-58 for 5 months.
He got his second boat, the larger U-562, on 4 Sept 1941. Oblt. Horst Hamm would take his U-562 out on 8 patrols, 241 days at sea, from Sept 1941. During this time he sank 6 ships with a total of 37,287 GRT and damaged one merchant of 3,359 GRT.
On 27 Nov 1941 U-562 passed the dangerous Straits of Gibraltar into the Mediterranean (Busch and Röll, 1997). The boat thus left the Atlantic for good, having completed one patrol there.
