Buildup and Training
The planning for an invasion in northwest Europe began years in advance, although it was not until December 1943, when General Dwight D. Eisenhower was appointed Supreme Commander of the Allied Expeditionary Force, that preparations for the future operation, code-named Overlord, intensified.
The Plan
Operation Fortitude successfully deceived German High Command into expecting a landing at Pas-de-Calais. Instead, the Allies targeted a 50-mile stretch of Normandy coastline. The plan had two components: Operation Neptune, the naval assault phase, and Operation Overlord, the broader invasion strategy. Approximately 160,000 Allied troops were to land across five beaches: Sword, Juno, Gold, Omaha, and Utah, with British and American airborne forces landing inland.
Planning for D-Day: Preparing Operation Overlord
Despite their early agreement on a strategy focused on defeating “Germany First,” the US and British Allies engaged in a lengthy and divisive debate over how exactly to conduct this strategy before they finally settled on a plan for Operation Overlord.
D-Day
Initially set for June 5, D-Day was delayed due to poor weather. With a small window of opportunity in the weather, Eisenhower decided to go—D-Day would be June 6, 1944. Paratroopers began landing after midnight, followed by a massive naval and aerial bombardment at 6:30 a.m. American forces faced severe resistance at Omaha and Utah Beaches. Despite challenges, including mislandings and fierce opposition, Allied forces established a critical beachhead in Normandy.
Hedgerow Fighting
For all of the preparations made for Overlord, the Allied forces were ill-equipped to fight in the hedgerows they quickly encountered in Normandy. The Normandy bocage presented unexpected challenges with its dense hedgerows and narrow roads. German forces used the hedgerows defensively, creating deadly killing fields that Allied troops had to cross. The Allies had to adapt their tactics to overcome these obstacles and advance.
The End of the Normandy Campaign
American forces isolated and captured Cherbourg by June 27, while British forces secured Caen by July 9. Despite these victories, progress was slow. On July 24–25, American forces launched Operation Cobra, breaking through German lines near Saint-Lô. This marked the end of the Normandy Campaign and the beginning of the Allied push to liberate northern France and Paris.
