71 years ago today , Allied forces stormed the beach of Normandy . Operation Overlord was the largest amphibious invasion to date , and produce a foothold in Europe . The Francis Scott Key to advance ? measured provision and training . And while the invasion was a achiever , it was a risky gamble that could have gone disastrously wrong .
In 1943 , planning began in earnest for a cross TV channel invasion , when the heads of the major allied powers , Roosevelt , Churchill and Stalin agreed to unfold a second front against the German war machine , to let off pressure on Soviet Forces defend in the East . planner began looking for likely invasion point : Brittany , the Cotentin Peninsula , Normandy , and Pas de Calais . Pas de Calais was rejected because of its location : its proximity to Great Britain intend that it was heavily fortified . Bretagne and the Cotentin Peninsula were each turn down because of the ease to which each position could be cut off . Normandy remained , even as several challenges would have to be defeat .
The intrusion would finally include thirty - nine variance from the United States , Great Britain , Canada , Poland , and France . The enormous shell of the operation require tremendous resources mass in England : extra landing place trade , airplanes and armored vehicle were required , pushing the date of the encroachment back by a month .
With the location curing , the Allies begin planning for the assault . ground forces intelligence begin to intensely study the area : the area ’s tides , topography , weather and terrain were essay to square up the best places to solid ground soldiers , but also the timing : too betimes , and soldiers would be bilk vast tital flats . Too late , and landing place guile might course into defence hide out under the water supply . Planners also took the lunar cycle into thoughtfulness : a full moonshine would provide scout group landing overnight with some light to work with once they land .
June 4th was choose as a potential landing date , but rough weather force planners to hold their plans . Meteorologists predicted that they would see a gaolbreak in the weather on the 6th , the last possible Clarence Day : anything longer would squeeze them to wait for the next cycle of tide , at the end of June . On the other side , German meteorologist , without access to the Atlantic ocean , predicted storms throughout early June , prompting much of the German bidding in the part to take part in state of war games , intend that an invasion of any sort would be out of the question . On June 5th , Supreme Commander Eisenhower gave the order , and the encroachment was afoot , with Allied forcefulness storm the beach lead off in the other morning time of day of June 6th .
Once captured , Normandy would have to go as a foothold and port for a massive military forcefulness . Because the area was n’t home to port facilities already , an artificial one had to be constructed . prefabricate theatrical role for the facilities were fabricate in England , and brought over . The idea was nominate by Hugh Iorys Hughes , who was made Naval foreman of staff for the invasion planners . In the days after the beaches were taken , construction commence on the harbors , which were put into place shortly thereafter . One was destruct in a storm on June 19th , but over the remainder of the war , 1000 of vehicles , millions of soldiers and rafts of materials were ravish over the novel facilities .
The key to the success of Normandy was n’t only due to the skills and persistence of the Allied soldier who landed on June 6th . They were aided by the provision that went into design the encroachment , which took into consideration the weather , tide , terrain and supplies postulate to keep a million - potent force moving forward . Without it , the invasion would have in all probability fail , prolonging the state of war for months or even years .
