hundred Silver Stars and three hundred Purple Hearts—dubbed “the German marksmanship medal”—for each major general to award as warranted, and ten thousand “Hagensen packs,” canvas bags sewn by sailmakers in lofts across England and stuffed with plastic explosive. A company contracted to deliver ten thousand metal crosses had missed its deadline; instead, Graves Registration units would improvise with wooden markers. Cotton mattress covers used as shrouds had been purchased on the basis of one for every 375 man-days in France, a formula that proved far too optimistic. In July, with supplies dwindling, quartermasters would be forced to ship another fifty thousand.
Four hospital ships made ready, “snowy white … with many bright new red crosses painted on the hull and painted flat on the boat deck,” the reporter Martha Gellhorn noted. Each LST also would carry at least two physicians and twenty Navy corpsmen to evacuate casualties, with operating rooms built on the open tank decks—a “cold, dirty trap,” in one officer’s estimation—and steam tables used to heat twenty-gallon sterilization cans. All told, OVERLORD would muster 8,000 doctors, 600,000 doses of penicillin, fifty tons of sulfa, and 800,000 pints of plasma meticulously segregated by black and white donors. Sixteen hundred pallets weighing half a ton each and designed to be dragged across the beaches were packed with enough medical supplies to last a fortnight.
A new Manual of Therapy incorporated hard-won lessons about combat medicine learned in the Mediterranean. Other lessons had still to be absorbed, such as how to avoid both the morphine poisoning too common in Italy and the fatal confusion by anesthesiologists of British carbon dioxide tanks with American oxygen tanks—both painted green—which had killed at least eight patients. Especially salutary was the recognition that whole blood complemented plasma in reviving the grievously wounded; medical planners intended to stockpile three thousand pints for OVERLORD ’s initial phase, one pint for every 2.2 wounded soldiers, almost a fourfold increase over the ratio used in Italy.
But whole blood would keep for two weeks at most. As the last week of May arrived, there could be little doubt that D-Day was near. The blood—in large, clearly marked canisters—had landed.

On Tuesday, May 23, a great migration of assault troops swept toward the English seaside and into a dozen marshaling areas—Americans on the southwest coast, British and Canadians in the south—where the final staging began. March rates called for each convoy to travel twenty-five miles in two hours, vehicles sixty yards apart, with a ten-minute halt before every even hour. Military policemen wearing brassards specially treated to detect poison gas waved traffic through intersections and thatched-roof villages. Soldiers snickered nervously at the new road signs reading “One Way.” “We sat on a hilltop and saw a dozen roads in the valleys below jammed with thousands of vehicles, men, and equipment moving toward the south,” wrote Sergeant Forrest C. Pogue, an Army historian. Pogue was reminded of Arthur Conan Doyle’s description of soldiers bound for battle: a “throng which set the old road smoking in the haze of white dust from Winchester to the narrow sea.”
Mothers held their children aloft from the curb to watch the armies pass. An old man “bent like a boomerang” and pushing a cart outside London yelled, “Good luck to yer all, me lads,” a British captain reported. On tanks and trucks, the captain added, men chalked the names of sweethearts left behind so that nearly every vehicle had a “patron girl-saint,” or perhaps a patron girl-sinner. Almost overnight the bright plumage of military uniforms in London dimmed as the capital thinned out. “Restaurants and night clubs were half empty, taxis became miraculously easier to find,” one account noted.
