. U-Boat crews almost always avoided deliberately engaging enemy destroyers, so Darings destruction was rightly seen as a very skillful attack by both Kretschmer and U-23.

In April 1940, after eight patrols, Kretschmer was transferred to the newly-completed Type VII B , and in a sense began his legacy. After two months' training and shakedown maneuvers in German waters, Kretschmer took the boat into action in June 1940. During U-99s first four patrols, Kretschmer commenced attacking convoys at night on the surface, sinking merchant ships with highly accurate shots, using only one torpedo

Kretschmer was meticulous in his conduct towards the crews of torpedoed ships. When attacking lone merchantmen in the days before wolfpack tactics began in earnest, he had been known to hand down bottles of spirits and blankets into lifeboats and give them a course to the nearest land. On one patrol in September 1940, Kretschmer had also recovered a survivor of another torpedo attack who was alone in the Atlantic on a small raft and took him aboard, transferring him to a lifeboat after his next successful attack.

On his last patrol in March 1941, he sank 10 more ships, but these were to be his last victims. On 17 March 1941, during a counterattack by the British escorts of Convoy HX-112

, was killed aboard , having being depth charged, rammed and sunk by Vanoc.

Kretschmer's usual standards of conduct were evident during the sinking of his boat; he signaled Walker asking for rescue for his men, taking care to ensure as many left the submarine as possible, and assisted some of his crew towards the rescue nets hung from the British destroyer. Kretschmer's strength was evidently failing in the cold ocean; his own rescue was at the hands of a British sailor who climbed down the nets and plucked him from the water.

U-23s career in the Black Sea

U-23 participated in an unusual operation by the Kriegsmarine. The boat, along with five others, was transferred overland and by river to the Romanian port of Constanza; from there they attacked Russian ships in the Black Sea. This group, the 30th Flotilla, sank many ships for the loss of three submarines, over two years. However, in August 1944, when Romania left the Axis, the 30th Flotilla was stranded with no way to return to Germany. The submarines were scuttled. S. Kolay, a Turkish marine engineer, recently found the final resting place of the three scuttled submarines and visited one of them, U-20.
