0200 Range had closed to 100 yds. Starboard searchlight switched on revealing a 500 ton U-boat swinging rapidly to starboard. Wheel was put hard-a-starboard in an attempt to ram and all guns that would bear opened fire. Ship turned inside the U-boat’s turning circle and came up alongside her starboard side with only a few feet separating the two. By this time the enemy was being illuminated by port searchlight and 10″ S.P. and was seen to be in a sinking condition.
