At 02.53 hours on 2 Jun, 1942, the unescorted and unarmed Illinois (Master Hans Mathiesen, lost) was torpedoed and sunk by U-159 about 400 miles northwest of Puerto Rico, while steaming a non-evasive course at 10 knots. Two torpedoes hit amidships, just aft of the bridge. The ship sank within 40 seconds, capsizing to starboard. No distress signal could be sent and no lifeboats could be launched. Only a few men of the eight officers and 30 crew members managed to leave the ship. One officer and five men rightened a capsized lifeboat and remained nearly 20 hours in the area before then sailing a southwesterly course, but found no other survivors. The survivors were picked up by the American steam tanker Esso Montpelier six days after the attack and landed at Port of Spain, Trinidad on 10 June.
