At 22.20 hours on 3 Aug, 1942, the unescorted Tricula (Master Oswald Eustace Sparrow) was hit by three torpedoes from U-108 and sank rapidly about 250 miles northeast of Trinidad. The U-boat had chased another tanker since 14.40 hours, when they came across two unescorted ships and the commander decided to let the first ship escape. After sinking the Tricula, the U-boat surfaced to chase the other freighter but it was already out of sight. The master, 42 crew members, three gunners and one passenger were lost. Eight crew members, two gunners and one passenger were picked up by the Argentinian steam merchant Rio San Juan and landed at Fernando, Cuba.
