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.

The Mediterranean
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.

Kapitänleutnant Horst Hamm and his entire crew of 49 men died when the U-562 was sunk in the Mediterranean north-east of Benghazi, Libya by British warships and aircraft (Niestlé, 1998).
