In response to TheExaminer's comment:
I need to read some more books about that. I still dont understand how those guys were able to get off those boats while being sprayed in the face with direct machine gun fire, wade ashore, establish a beach head, then take the pillbox covered heights above the beach. Amazing. Hard to imagine any assault with more bravery than that since the Civil War.
purely numbers. you can only shoot at 1 thing at a time.
On D-Day, the Allies landed around 156,000 troops in Normandy. The American forces landed numbered 73,000: 23,250 on Utah Beach, 34,250 on Omaha Beach, and 15,500 airborne troops. In the British and Canadian sector, 83,115 troops were landed (61,715 of them British): 24,970 on Gold Beach, 21,400 on Juno Beach, 28,845 on Sword Beach, and 7900 airborne troops.
11,590 aircraft were available to support the landings. On D-Day, Allied aircraft flew 14,674 sorties, and 127 were lost.
In the airborne landings on both flanks of the beaches, 2395 aircraft and 867 gliders of the RAF and USAAF were used on D-Day.
Operation Neptune involved huge naval forces, including 6939 vessels: 1213 naval combat ships, 4126 landing ships and landing craft, 736 ancillary craft and 864 merchant vessels. Some 195,700 personnel were assigned to Operation Neptune: 52,889 US, 112,824 British, and 4988 from other Allied countries.
By the end of 11 June (D + 5), 326,547 troops, 54,186 vehicles and 104,428 tons of supplies had been landed on the beaches.
As well as the troops who landed in Normandy on D-Day, and those in supporting roles at sea and in the air, millions more men and women in the Allied countries were involved in the preparations for D-Day. They played thousands of different roles, both in the armed forces and as civilians.
