Service record
On June 14, 1941, eleven days into her thirty-three day first patrol while en route from Kiel to St. Nazaire, U-751 attacked and sank the British ship St Lindsay (5,370 GRT).

Arriving at St. Nazaire on July 5, U-751 stayed in port for thirty-four days before going on her second patrol. She attacked no ships on her second and third voyages.

Five days into her fourth patrol, on December 21, 1941, U-751 attacked and sank the HMS Audacity (D10), an Escort carrier attached with British convoy HG 76.

On January 14, 1942, U-751 left St. Nazaire on her fifth patrol, destined to return on February 23. Nineteen days into this patrol, on February 2, U-751 attacked and damaged the Dutch ship Corilla, part of convoy HX 173 (8,096 GRT). Two days later, she sank the British ship Silveray, adding another 4,535 GRT to her score. Another British ship, Empire Sun, was sunk another three days later, for 6,952 GRT.
