Shortly after midnight on 6 June 1944, known otherwise as D-Day, men of Major John Howard's 'D' Company of the 2nd Battalion, Oxfordshire and Buckinghamshire Light Infantry (2 OBLI), a glider infantry unit forming part of the 6th Airlanding Brigade, landed in glider and captured the Caen canal and Orne river bridges (now known as Pegasus Bridge and Horsa Bridge) via coup de main. It was achieved with light casualties. The two parachute brigades, the 3rd and 5th, landed soon after and landed, for the most part, where intended, although numbers of paratroopers dropped in the flooded countryside. The Merville Gun Battery also fell, although with heavy losses to Lieutenant-Colonel Alastair Pearson's 8th Parachute Battalion. At dawn, Gale himself landed in Normandy by glider. By midday on D-Day elements of Brigadier Lord Lovat's 1st Special Service Brigade had landed at Sword Beach, with the British 3rd Infantry Division following, and began to relieve the airborne troops at the bridges. The arrival of the rest of the 6th Airlanding Brigade in the evening, in Operation Mallard, completed the 6th Airborne Division's concentration in Normandy.
