At 05.01 hours on 3 Jun, 1942, U-404 attacked the unescorted and unarmed Anna (Master John Svensson) with gunfire about 245 miles northwest of Bermuda, after two torpedoes fired at 03.09 and 04.50 hours had missed. After 7 minutes the gun crew had to cease fire because they were blinded by a searchlight from the ship which then tried to communicate with the U-boat by blinking light. In the moonlight the Germans could see Swedish neutrality markings, but decided to continue the attack because the ship was sailing without lights on a zigzag course. At 08.50 hours, three rounds were fired from close distance into one of the holds, causing a fire and the Anna to sink by the stern at 09.55 hours. The entire crew was rescued and landed at the US East coast.
