At 15.32 hours on 21 Feb 1942 the unescorted Kongsgaard (Master Leif Moen) was attacked by U-67 with two torpedoes seven miles west of Noordpunt, Curaçao. One torpedo was seen by the master and he tried to evade, but one of the torpedoes struck on the port side between the bridge and the poop deck. The cargo caught fire, sending flames high above the entire afterpart. A dinghy was thrown overboard, whereupon two men tried to save themselves in it, but the flames caught up with them. Some men amidships lowered the starboard boat and then rowed away as fast as they could, after having fished some men out of the sea. At 19.02 hours, the U-boat fired a coup de grâce, which missed and at 19.30 hours a second, which struck the afterpart and caused the tanker to sink about seven miles west of North Point.

The master and seven survivors in the lifeboat were rescued by a fishing vessel three hours later and taken to Curaçao. An ninth survivor was also picked up, he jumped off the afterpart and swam through the flames which had quickly spread on the water after the explosion, until he reached open water.
