Reinhard Hardegen was another U-Boat commander doing his job for which he had no real interest in. Reinhard Hardegen was also openly critical of the politics which sent him to sea in the first place.
Quote : Hardegen was not enamored with the Nazi regime; he openly disagreed with Nazi politics. He also, as U-Boat historian
Michael Gannon documents meticulously with accounts from survivors, furnished food and navigational directions to the lifeboats of torpedoed merchantmen when possible and, in at least one case, forcibly halted a neutral ship to have it pick up survivors of a vessel he had sunk nearby.

A decent man caught up in the ugliness of war.
Fair winds and calm seas.
