U-632 23 Jul 1942 6 Apr 1943  (+)  2 patrols (71 days) 

On 18 March, 1943 Hans Karpf’s wife gave birth to a daughter (later named Inge). Two weeks later his boat was sunk with all hands in the Atlantic off Iceland .

His daughter had wondered whether Karpf had known he had a child.

After Inge contacted him with this question in 1981, archivist and author Timothy Mulligan of the US National Archives waded through masses of decoded messages transmitted to U-632 on her final patrol, and finally found the thrilling text “Hero daughter born on 18 March. Congratulations”, sent by BdU (U-boat Control) 24 March. So Hans Karpf had known he was a father for two weeks before his death. (The Virginian-Pilot, 2007)
