On 14 November 1942, she sank the 20,107 GRT troop transport ship MV ''[[List of shipwrecks in November 1942#14 November|Warwick Castle]]'' (one of the largest sunk in World War II).

At 08:44, the ship, under the command of Henry Richard Leepman-Shaw in [[Convoy MKF-1X]] was hit by one of two torpedoes fired, about {{convert|200|nmi}} NW of [[Cape Espichel]], Portugal. The U-boat hit her again at 08:57, causing the ship to sink about one hour later. The master, 61 crew members and 34 service personnel died. 201 crew members, 29 gunners and five naval and 131 service personnel were rescued by {{HMS|Achates|H12|6}}, {{HMS|Vansittart}}, {{HMCS|Louisburg|K143|6}}, and the British {{MV|Leinster}}. The latter ship had been in [[Convoy KMF-1]] for [[Operation Torch]] (the invasion of North Africa).

On 19 November 1942, ''U-413'' was attacked by a British [[Lockheed Hudson]] aircraft with five bombs and was damaged so severely that she had to return to a new base - [[Brest, France|Brest]] in occupied France.

Her second patrol was marked by sinking the American ship ''[[List of shipwrecks in February 1943#5 February|West Portal]]'' in mid-Atlantic on 5 February 1943; there were no survivors. She also attacked and sank the Greek ''[[List of shipwrecks in January 1943#22 January|Mount Mycale]]'' on 22 January 1943, northeast of [[Newfoundland (island)|Newfoundland]].
