Most of the crew remained on the deck of the submarine as Thompson circled above them, his aircraft now joined by a second Hudson that had been en route from Scotland to Iceland and had broken off its journey to lend assistance. A radio request for help saw a Consolidated Catalina flying boat of 209 Squadron being scrambled at Reykjavík; it reached the scene three hours later. The German crew radioed their situation to the German naval high-command, destroyed their radio, smashed their Enigma machine, and dumped its parts overboard along with the boat's secret papers. Admiral Dönitz later noted in his war diary that he ordered U-boats in the area to go to "U-570"s assistance after receiving this report; responded, but Allied air patrols prevented "U-82" from reaching "U-570".
