On 13 July 1942 U-562 fired a spread of four torpedoes from 2800 meters at a small convoy but missed. At 00.46 hours on next day, Hamm fired two torpedoes at the same convoy and he thought both had hit and claimed a tanker of 7000 tons sunk. In fact, the Adinda was hit by one torpedo, but the engine was not damaged and she could proceed to Haifa three hours later, where she arrived at 14.00 hours and recieved temporary repairs. In September 1942 the tanker left for Alexandria, was repaired and returned to service in August 1944.
