Navy Unit Citation to USS BUCKLEY (DE-51) for sinking the U-66. During the pre-dawn hours of his 28th birthday (6 May 1944), Abel's ship engaged a surfaced German submarine, U-66 in the Atlantic about 500 nm off the coast of North Africa in what has been called the "most exciting" submarine engagement of WW2. After the U-boat sank, about half its crew, 36 German sailors, were rescued and taken prisoner by BUCKLEY. This battle is probably the closest naval combat of modern warfare, as BUCKLEY'S crew battled German sailors who swarmed about the destroyer with shell cases, fists and coffee cups, after BUCKLEY rammed the submarine and rode up on its back.
