40s WW2 Vintage Stencilled US-Navy Foul Weather Parka

"Three more squadrons of PT's were sent to the Channel to join the screening forces in the invasion of Normandy, though only one of them, Squadron 34, 12 Elco boats, commanded by Lt. Allen H. Harris, USNR, was in time to take part in the operations on D-day, June 6, 1944. Squadron 34 arrived in England in May; Squadron 35, 12 Elco boats, under Lt. Comdr. Richard Davis, Jr., on June 4; and Squadron 30, 6 Higgins boats, under Lt. Robert L. Searles, USNR, on June 7. Also in June, Lieutenant Commander Bulkeley was designated a task group commander in charge of all PT operations during the invasion of Normandy."

"The PT's of Squadron 34, in divisions of three, were to escort four groups of minesweepers in advance of the invasion fleet to clear a broad sealane to the beaches and the fire support areas offshore. The first group, PT's 500, 498, and 509, under Lt. Herbert J. Sherertz, USNR, nearly invaded France a day too soon. D-day had been scheduled for June 5, so early on the morning of the 4th the boats rendezvoused with their minesweepers and set out from the Isle of Wight for the Baie de la Seine. Later in the morning the PT base at Portland received belated notice that D-day had been postponed until June 6. Fortunately, a patrolling destroyer was able to intercept the boats, already halfway to France, and send them back to Portland."
