On April 21, 1945, TG 22.13 was on barrier patrol in the Atlantic, in mid-ocean about 550
miles northwest of the Azores. The group was under the command of M. H. Harris, USNR.
On the night of April 21-22, this hunter-killer group was directed to leave the patrol area
and proceed to Argentia, Newfoundland. The ships headed westward in the evening. Moonlight was blurred by a light overcast, but the seascape, wind-roughened, was illumined,
with 5 mile visibility.
They had been steaming westward for about 40 minutes when the group's flagship, USS Carter DE
112, swept up a submarine contact. The team went into action. While Carter held contact, USS Neal A. Scott DE 769 was coached in for an attack. Two other DEs, USS Muir
DE 770 and USS Sutton DE 771 were directed to circle the area of contact.
The play, then, fell to Neal A. Scott. At 2156 Scott had a sonar bead on the U-boat and
opened fire with hedgehog. Two muffled explosions indicated hits at a depth of some 400 feet.
At 2205 Carter attacked with hedgehog. Again the water echoed to several deep
explosions. These detonations were immediately followed by a deep-sea blast. Ten minutes later the depths emitted a volcanic thunder that was felt and heard by all hands
in Carter and Scott.
The DEs continued to probe and "ping". But the submarine was not there. Searching
the surface, they found a significant oil slick and floating trash. Among the residue were scraps of paper, shattered wood and two tattered wooden boxes. The victim
under this rubbish was eventually identified as the U-518.
USS Carter and USS Neal A. Scott had sunk the fifth U-boat to be downed by American
destroyermen that month.
