U-135 only suffered minor damage, but one crewman had been killed by gunfire and another died of wounds one hour after the attack. [Matrosenobergefreiter Emil Hafner, Matrosenobergefreiter Erhard Pömpner]

The Germans were surprised, fought off the first attack and then dived. Most damages were repaired by the crew and the boat continued its patrol, but later they found leaks from this attack that forced them to return to base on 28 February. (Sources: Rohwer/Ritschel)
