earlier by three airborne divisions to secure the beachhead flanks and help the mechanized forces thrust inland. This grander OVERLORD required 230 additional support ships and landing vessels such as the big LSTs—“landing ship, tank”—that had proved invaluable during the assaults at Sicily, Salerno, and Anzio. Assembling that larger fleet had in turn meant postponing the Normandy invasion from May until early June, and delaying indefinitely an invasion of southern France originally scheduled to occur at the same moment.
As he unfolded his plan, Montgomery meandered across the plaster beaches and the tiny Norman villages, head bowed, eyes darting, hands clasped behind his back except when he pinched his left cheek in a characteristic gesture of contemplation, or when he stressed a particular point with a flat stroke of his palm. Often he repeated himself for emphasis, voice rising in the second iteration. He was, one staff officer observed, “essentially didactic by temperament and liked a captive audience.” No audience had ever been more rapt, the officers perched on those unforgiving benches, bundled in their blankets and craning their necks. Only Churchill interrupted with mutterings about too many vehicles in the invasion brigades at the expense of too few cutthroat foot soldiers. And was it true, he subsequently demanded, that the great force would include two thousand clerks to keep records?
Montgomery pressed ahead. Hitler’s so-called Atlantic Wall now fell under the command of an old adversary, Field Marshal Erwin Rommel. German divisions in western Europe had nearly doubled since October, from thirty-seven to almost sixty, one reason that Montgomery had insisted on a heftier invasion force. He continued:
Last February, Rommel took command from Holland to the Loire. It is now clear that his intention is to deny any penetration. OVERLORD is to be defeated on the beaches.… Rommel is an energetic and determined commander. He has made a world of difference since he took over. He is best at the spoiling attack; his forte is disruption.… He will do his level best to “Dunkirk” us— not to fight the armored battle on ground of his own choosing, but to avoid it altogether by preventing our tanks landing, by using his own tanks well forward.
Some officers in SHAEF—Eisenhower’s Supreme Headquarters Allied Expeditionary Force—believed that German resistance might collapse from internal weaknesses, with the result that OVERLORD would quickly become an occupation force. Montgomery disagreed, and he ticked off the expected enemy counterpunch. Five German divisions, including the 21st Panzer Division, would oppose the invaders on D-Day; by dusk, two other panzer divisions could join the fight, reinforced by two more at the end of D + 1, the second day of the invasion, for a total of nine German divisions battling eight Allied divisions ashore. “After a sea voyage and a landing on a strange coast, there is always some loss of cohesion,” Montgomery said, swatting away the understatement with his palm. A death struggle to amass combat power would determine the battle: OVERLORD ’s plan called for Allied reinforcements to land at the rate of one and one-third divisions each day, but a bit more than a week into the fight, two dozen German divisions could well try to fling eighteen Allied divisions back into the sea.
Montgomery envisioned a battle beyond the beaches in which the British and Canadian Second Army on the left grappled with the main force of German defenders, while the American First Army on the right invested Cherbourg. Three weeks or so after the initial landings, Patton’s Third Army would thunder into France, swing through Brittany to capture more ports, and then wheel to the river Seine around D + 90, three months into the operation. Paris likely would be liberated in mid-fall, giving the Allies a lodgement between the Seine and the river Loire to stage for the fateful drive on
