At 09.35 hours on 23 Nov, 1943, the unescorted Elizabeth Kellogg (Master Norman Thomson Henderson) was hit by one torpedo from U-516 150 miles north of Cristobal. The torpedo struck on the port side at the #4 tank amidships. The explosion ruptured the #2, #3 and #4 port tanks and threw burning oil all over the ship. The ship caught fire from the bridge to the poop deck and killed all the deck officers. Flames shot through the ventilators into the engine room and prevented the watch below from throttling down the engines. The survivors of seven officers, 29 men and twelve armed guards (the ship was armed with one 4in, two .50cal and two .30cal guns) abandoned ship in two lifeboats, two rafts and others jumped into the water. The burning tanker with engines full speed astern and her rudder hard aport made large circles around the survivors. The master, four other officers, three men and two armed guards died in the attack. The after magazine exploded after six hours, broke her back and the fire burned out after about twelve hours. An aircraft spotted the stopped tanker, took a picture and reported the position. The American tug USS Favorite (IX 45) and several escort vessels were sent to salvage the ship, but the vessel sank before they arrived. On 24 November, the Army tanker USAT Y-10 picked up six survivors and the submarine chaser USS SC-1017 the remaining survivors. All were landed in Cristobal the same day.
