  • It was the Largest Water-Borne Attack in History

D-Day was the largest amphibious invasion on any shoreline in history. The assault was coordinated in two main phases- an airborne assault and amphibious landings on Nazi-occupied France.

The Allied airborne forces used naval vessels and landing craft to disembark thousands of troops on 5 beaches in Normandy. The five assault beaches included Utah, Omaha, Gold, Juno, and Sword.

Allied paratroopers also carried out bombardments on German coastal defenses prior to and during landing. They provided artillery and tactical support for the attacking troops and infantry division on the beaches.

  • D-Day Comprehensive Plan Was After Tehran Conference

In December 1943, the first commander team led by American General Dwight D. Eisenhower was formed to plan the marine, air, and land military operations.

Lieutenant-General Frederick Morgan and his colleagues of British, American, and Canadian officers submitted plans for the assault in July 1943. Soon after the clearance of Dunkirk in 1940, minimal planning of the attack commenced.

It was only after Tehran Conference in late 1943 that a compressive preparation for operation Overload began.

Part of the plan was to gather unlimited resources for the invasion. Therefore, the British factories expanded production. They managed to ship equipment and supplies across the Atlantic from North America to Britain.

  • D-Day Is More Than a Key Military Victory

  • Poor Weather Didn’t Stop the Attack

Nature played a vital role on June 6, 1944. The beach obstacles were not ideal for an assault, but further postponing meant a two-week delay. Allies relied on natural illumination and had to invade on a full moon night, and by June 5 that window was beginning to close.

It was hard to navigate the ocean due to the strong winds and rough sea that posed a challenge for the landing crafts. Poor weather triggered the tide quicker than it was anticipated.

Eisenhower ordered an attack on June 6, 1944. Luckily, the crucial full moon was out, and the angry skies kept German planes grounded.


The legacy set by D-Day resonates through history. Despite all the formidable odds, the Allied military succeeded in the fight. They victoriously managed to turn the tide of World War II towards triumph against Hitler’s forces.
