The division would use approximately 350 gliders for the operation, the majority of which would transport 6th Airlanding Brigade. This number included thirty-four Hamilcars; four would land in landing zone 'N' between 03:00 and 04:30 in support of the operations of 3rd Parachute Brigade and 5th Parachute Brigade, and would carry four 17-pounder anti-tank guns and their transport vehicles and crews. The other thirty would land at approximately 21:00 in landing-zone 'W' as part of a reinforcement lift. Twenty of the Hamilcars would carry Tetrarch light tanks and their crews which belonged to 6th Airborne Armoured Reconnaissance Regiment, four more carried three Rota trailers without crews, and another three carried Universal Carriers with their crews. The last three carried two Universal Carriers converted to accommodate a 3-inch mortar, one Universal Carrier which carried a slave battery, sixteen motorcycles and a jeep. The four Hamilcars which were to land in support of 3rd and 5th Parachute Brigades took off from Tarrant Rushton at 02:10 on 6 June and were due to land at approximately 03:30; however, only two landed successfully. One suffered a broken tow rope shortly after it took off, although it was able to land safely at an airfield in England; the other reached the Normandy coast, but the tow rope was disconnected too early and it landed a considerable distance away from the landing zone. When dawn broke, it was discovered by German forces and attacked; four of the crew and passengers were killed and one captured, but the rest managed to escape.
