From 1942 onwards the Allied Forces realised that an attack would have to be made on mainland Europe in order to stop the Nazi advance. Over the course of the next two years, victories were achieved in North Africa and Southern Italy but France; with its expansive coastline and locality to Britain was always going to be the main battleground that would establish the outcome of the Second World War. In Spring 1943, General Frederick Morgan, the man entrusted to plan the Allied invasion, made his choice as to where the invasion would take place. This would have been an extremely difficult decision as the factors affecting the location were almost infinite. It needed to be easily accessible from the sea but difficult for the Germans to access by land.
Morgan realised that transporting thousands of men, arms and supplies across the channel would be a major logistical problem and that the shorter the water crossing the better. As the geography of the English Channel shows, this would lead him to believe that the nearer he could get to Calais, the greater the chance of success. However, he also was aware that the further east he planned the invasion the stronger would be the German opposition. He would need to find a stretch of northern French coastline, which was not more than a hundred miles from Britain and was poorly defended. General Morgan was not overwhelmed with options.
The deciding factor in choosing the exact location of the invasion was the formation, two years earlier, of the British Airborne Forces. If troops could be glider-landed or parachuted inland, then they could prevent German reinforcements from arriving at the invasion beaches where the main body of troops would disembark. With this extra string to the Allied Forces' bow, a site was chosen with Airborne soldiers in mind. The invasion beaches were to be on the Normandy coastline, just west of the mouth of the Orne river. By landing here, the invasion army would have the protection of the Orne and the adjacent Caen Canal on their west flank. General Morgan knew that, once the Germans realised that this was the real invasion, it would not take them long to launch a counteroffensive. Using Intelligence reports Morgan would know the size of the German forces in the Caen area and could thus start formulating the number of troops needed for the invasion.
At this time, there were two airborne divisions, 1st and 6th (they were numbered this way to confuse German intelligence). 1st Airborne were fighting in Southern Italy and so 6th Airborne Division, commanded by General Richard "Windy" Gale were the force chosen to lead the airborne assault. The chief role of 6th Airborne would be to capture and hold the bridges over the Orne and Caen Canal. These two bridges were a kilometre apart between the towns of Bénouville and Ranville. They were the only crossing points between Caen and the coast. If these bridges could be taken and held, then the Germans would find it hard to counterattack in large enough numbers to push the invasion army back into the sea.

By January 1944 a plan had been formulated at COSSAC, (Chief of Staff, Supreme Allied Commander) for a full scale invasion of France via the Normandy beaches for June that year. This plan was still highly top secret (the word Bigot was used, meaning top top secret). However, at this stage General Gale was let in on the plan, his briefing was to capture intact the bridges over the Caen Canal and River Orne, to blow the bridges over the River Dives and to destroy the Merville Battery. The latter two operations would pose few logistical problems for Gale. Paratroopers would be used to destroy the Merville Battery and bridges at Dives, however the problem of taking the other two bridges intact would prove the cause of many sleepless nights for Gale.
Paratroopers could not be expected to land at night, near the coast, in high winds and then regroup in order to fight such a vital battle. Gale remembered the German attacks at Fort Eben Emael in Belgium (1940) and in particular the Corinth Canal in Greece (1941) where the German airborne had been used not as paratroopers but glider troopers. A plan was constructed where six gliders, three per bridge, would be landed on the farm land adjacent to the bridges and the bridges would be taken in a "coup de main" attack.
With the plan now consolidated, Gale's attentions now turned to discovering which company in his division was the strongest. In April 1944, 6th Airborne carried out several exercises, designed by Gale to determine which unit would be the most suited to the operation. The central feature of this series of operations was a three-day exercise named Operation Deadstick. Although the soldiers did not know it at the time they were carrying out an almost exact replica of what they would be doing in Normandy two months later. The operation was an unequivocal success and one company in particular impressed General Gale. D Company, 2nd Battalion The Oxfordshire and Buckinghamshire Light Infantry, under the leadership of Major John Howard achieved the aim of capturing two bridges intact after a glider landing. Gale nicknamed D Company "the Bridge Prangers" and so a group of men had been found who would lead the invasion.
