USS Leopold (DE-319)

After structural firing tests at Galveston, Texas she departed for New Orleans. On 7 November, she proceeded to Great Sound, Bermuda where shakedown exercises were begun. On 9 December, she left for Charleston, South Carolina and 11 days of post-shakedown availability.

After four days of training exercises for officers and her nucleus crew for new destroyer escorts in the Chesapeake Bay area, Leopold stood out of Thimble Shoal Channel on 24 December 1943 as part of Task Force 61 (TF 61), escorting convoy UGS-68 to the Mediterranean. On 30 December, Leopold was directed to go to the rear of the convoy and search for a seaman reported lost overboard from one of the convoy ships. It was very dark and fairly rough, so, unless the seaman had on a life jacket with a light, the chances of finding him were slight. After 45 minutes, she discontinued the search. The convoy reached the Straits of Gibraltar on 10 January and was turned over to British escorts. Leopold moored at Casablanca the next day. On 13 January, she commenced patrolling as anti-submarine screen across the Atlantic side of the Straits of Gibraltar, TF 61 forming a line to prevent U-boats from entering the Mediterranean. On 15 January, she moored at Gibraltar, and the following day, proceeded out of the inner harbor to close up the stragglers on west-bound convoy GUS-27. On 1 February, a northwesterly gale caused the convoy to scatter and much time was consumed rounding up stragglers. Leopold arrived at New York on 4 February for ten days availability at the Navy Yard. From 14–27 February, Leopold — with other escorts of Escort Division 22 (CortDiv 22) — underwent training exercises at Casco Bay, Maine.

Departing New York on 1 March on her second voyage, Leopold took her screening station — as part of CortDiv 22 — with the 27-ship convoy CU-16 bound for the British Isles. On 8 March, she reported an HF/DF intercept which indicated an enemy submarine on the route of the convoy. The route was consequently altered. On 9 March, while south of Iceland, she reported a radar contact at 19:50 at 8,000 yd (7,300 m), which placed it 7 mi (11 km) south of the convoy at 57°37′0″N 26°30′0″W. Assisted by the destroyer escort Joyce (Captained by Lt. Comdr. R. Wilcox, U.S. Coast Guard), Leopold was ordered to intercept. General Quarters was sounded and orders were issued to "fire on sight." A flare was released and gun crew strained to sight the submarine in the lighted area. The U-boat was almost submerged when spotted and the gun crews had to work blind. Leopold was struck by an acoustic torpedo fired from the German submarine U-255. Shortly after the torpedo strike, the crew of Leopold began to abandon ship as she broke in half.

Joyce rescued 28 survivors at the close of the action; 171 others were lost through the explosion on board, drowning, and - most of all - cold water immersion. Leopold's bow remained afloat until early the next morning until sunk as a hazard to navigation by gunfire from Joyce 400 miles south of Iceland.

In 2017 Lyons Press published Never to Return by Randall Peffer and Col. Robert Nersasian. Through the use of extensive interviews with survivors of Leopold, Joyce, and the German submarine U-255, the book tells the story of the battle and the struggles of the 28 men who survived. The book also resolves unanswered questions about why it took Joyce so long to begin rescuing the crew of Leopold from the icy water. Col. Nersasian's brother Sparky was one of the 28 survivors.
