At 18.16 hours on 15 Nov 1940 the Havbør (Master Halvor Skarrebo) was hit on the port side aft by one torpedo from U-65, while picking up 31 men from rafts from the Kohinur, which had been torpedoed three hours earlier by the same U-boat. The men on the raft had warned the Havbør that the U-boat was nearby, but boats were lowered anyway. The ship immediately caught fire after being hit and some of the rafts and lifeboats were trapped by burning oil. The Germans initially planned to question the survivors but after observing the results of their attack left the burning tanker, which sank about 7 hours after the attack. The master, 27 crew members and all the rescued men died in the flames. Three Norwegian and two Danish crew members of the tanker jumped overboard and swam towards the abandoned raft from the other ship, tore a plank loose and paddled for life away from the burning oil.

Later the survivors encountered a lifeboat from Kohinur and asked to be taken on board, but after having inquired how much water they had on the raft, the lifeboat sailed away from the raft, because it was already filled to capacity. The raft kept drifting and on 16 November, one of the Danish men died, he had been badly burnt. On 24 November, the remaining survivors were picked up by the British steam merchant Baron Ardrossan and taken to Freetown.
