More than 150,000 Allied troops from various nations, mainly the United States, the United Kingdom and Canada, were prepared for the invasion. Thousands of vehicles, tanks and hundreds of ships and aircraft were mobilized. The troops underwent months of intensive training. A disinformation campaign, called Operation Fortitude, was also implemented to deceive the Germans about the true intentions of the Allies.
The landing originally planned for June 5 was postponed by one day due to bad weather conditions. June 6 was chosen because of a small window of favorable conditions. And it was on the night of June 5-6 that Operation Deadstick took place.
Under the command of Major John Howard, the operation was led by the British 6th Airborne Division. The primary objective of Operation Deadstick was to capture intact two strategic bridges, crucial points for securing the eastern flank of the landing beaches and to prevent German forces from counterattacking Allied troops landing on Sword Beach, one of the five Allied landing beaches in Normandy.
