 On 16 October, just 18 days after she left Bergen in Norway, a patrolling aircraft spotted "U-470" with her sister boats whilst they were still a long distance from their targets.The aircraft radioed back to base, and soon a whole swarm of British Royal Air Force B-24 Liberator bombers from 59 and 120 Squadrons had descended on the trio, who decided to battle it out on the surface rather than dive, which would have made them easy targets for depth charges.Over the course of the next several hours, the Liberators attacked the U-boats again and again, losing two of their number to anti-aircraft fire, one with all aboard and the other with two fatalities amongst the crew.
