USS Buckley

Between July 1943 and 22 April 1944, Buckley operated along the eastern seaboard as training ship for prospective officers and nucleus crews of other destroyer escorts.

On 22 April 1944, she joined hunter-killer Task Group 21.11 (TG 21.11) for a sweep of the North Atlantic and Mediterranean convoy routes. On the morning of 6 May, aircraft from the escort carrier Block Island (CVE-21) reported an enemy submarine near Buckley. She steamed toward the surfaced submarine, evading her torpedoes and gunfire, and commenced firing. At 0328 Buckley rammed the German submarine U-66 and then backed off. Shortly thereafter, the submarine struck Buckley, opening a hole in the escort vessel's starboard side. Hand-to-hand combat ensued between crew members of the two combatants on Buckley's foredeck, involving, among other weapons, coffee mugs and shell casings. The U-66 drew astern of Buckley and sank at 0341 in 17°17′N 32°24′W, after hand grenades were dropped down its hatch.

Buckley picked up 36 German survivors, transferred them to the Block Island and then retired to New York where she underwent repairs until 14 June 1944. For this most interesting action, regarded by several high naval officers as being the most "exciting" anti-submarine kill in the Battle of the Atlantic, Buckley personnel were authorized to wear a combat star in the European-African Theater ribbon. The then commanding officer, Lt. Comdr. Brent M. Abel, USNR, of Cambridge, Massachusetts, was awarded the Navy Cross for his part in its execution.

After completing refresher training at Casco Bay, Maine, in July 1944, Buckley escorted two convoys to North Africa (14 July – 7 November 1944). She then operated on anti-submarine and convoy escort duty along the eastern seaboard and in the North Atlantic until June 1945. During this period Buckley and Reuben James (DE-153) sank the German submarine U-548 on 19 April 1945 in 42°19′N 61°45′W. Buckley escorted one more convoy to Algeria during June–July 1945, before returning to the United States.

Buckley after her conversion, in late 1945.

Upon her return to the east coast, she commenced conversion to a radar picket ship. In October 1945, she participated in the Navy Day ceremonies at Jacksonville, Florida, and then on 31 October reported to the 16th Fleet at St. Johns River, Florida. Buckley was placed out of commission in reserve on 3 July 1946. On 26 April 1949 her classification was changed to DER-51 (radar picket destroyer escort), and on 29 September 1954, she was reclassified back to DE-51.

Buckley was stricken from the Naval Vessel Register on 1 June 1968; she was sold for scrapping July 1969.
