In the early hours of 15 October Thurmann of U-553 reported his contact to U-boat Command (BdU) and was ordered to shadow, whilst other U-boats were gathered for the attack.
In September 1943 BdU had established the patrol line Leuthen of 21 U-boats south of Greenland; these were to intercept west-bound convoys as they were about to enter the Greenland Air Gap, where Allied aircraft were reckoned to be unable to operate due to the extreme range.
