Editing German submarine U-413 (section)

===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.
