Attacks on this boat and other events

5 Nov 1942
19.18 hrs, Black Sea, off Poti, Georgia: U-24 fired a G7e torpedo at Soviet M/S trawler T-492, which passed beneath the target below the bridge. The trawler then forced U-24 to dive with gunfire. U-24 scored a hit at 21.37 hrs, but the torpedo was a dud. After U-24 had fired and missed with her last torpedo at 00.38 hrs on 6 November, the boat surfaced and exchanged fire with the 20mm AA gun, which malfunctioned shortly afterwards, forcing U-24 to break off the attack with slight damage to the conning tower from machine gun fire. (Sources: Ritschel)

29 Nov 1942
While patrolling in the Black Sea, Turkish coastal artillery fired three rounds at U-24, forcing her to dive. The commander stated that the boat was 7 or 8 nautical miles away from the Turkish coast at the time.

27 May 1944
The boat fought a surface battle with two Soviet patrol boats SW of Poti in the Black Sea. One man was killed and two wounded. [Matrosenobergefreiter Johann Wölbitsch]
