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]].

===Third and fourth patrols===
Her third patrol saw her leave Brest on 29 March 1943, once more for the Atlantic. There, she sank the British vessel ''Wanstead'' south of Greenland, whose survivors were picked up by the corvette {{HMS|Poppy|K213|6}} and the ASW (anti-submarine warfare) {{HMS|Northern Gift}}.

Her fourth sortie was a frustrating one; it was split into three parts, but she failed to sink any ships.

===Fifth and sixth patrols===
On 20 February 1944, she sank the British 1,100 tons destroyer {{HMS|Warwick|D25|6}} about 15 miles off [[Trevose Head]], north Cornwall. This was Poel's last patrol. He moved to the [[Naval Academy Mürwik]] in [[Flensburg]].

===Seventh patrol and sinking===
Her last victory was when she sank ''Saint Enogat'' on 19 August 1944 in the [[English Channel]].

''U-413'' did not suffer any casualties until 20 August 1944, when she was sunk, by one of the 115 strategically placed Naval Mines in the Cornish corridor 15 miles off the coast from Padstow. 45 of her crew were killed; there was one survivor.

The wreck of ''U-413'' was located and identified by marine archaeologist [[Innes McCartney]] in 2000 close to the official sinking position.
