The first Allied action of D-Day was Operation Deadstick, a glider assault at 00:16 at Pegasus Bridge over the Caen Canal and the bridge (since renamed Horsa Bridge) over the Orne, half a mile (800 metres) to the east.
Both bridges were quickly captured intact, with light casualties, by members of the 5th Parachute Brigade and the 7th (Light Infantry) Parachute Battalion.
The five bridges over the Dives were destroyed with minimal difficulty by the 3rd Parachute Brigade.
Meanwhile, the pathfinders tasked with setting up radar beacons and lights for further paratroopers (scheduled to begin arriving at 00:50 to clear the landing zone north of Ranville) were blown off course, and had to set up the navigation aids too far east.
Many paratroopers, also blown too far east, landed far from their intended drop zones; some took hours or even days to be reunited with their units.
Major General Richard Gale arrived in the third wave of gliders at 03:30, along with equipment, such as antitank guns and jeeps, and more troops to help secure the area from counter-attacks, which were initially staged only by troops in the immediate vicinity of the landings.
At 02:00, the commander of the German 716th Infantry Division ordered Feuchtinger to move his 21st Panzer Division into position to counter-attack.
However, as the division was part of the armoured reserve, Feuchtinger was obliged to seek clearance from OKW before he could commit his formation.
Feuchtinger did not receive orders until nearly 09:00, but in the meantime on his own initiative he put together a battle group (including tanks) to fight the British forces east of the Orne.

Only 160 men out of the 600 members of the 9th Battalion tasked with eliminating the enemy battery at Merville arrived at the rendezvous point.
Lieutenant Colonel Terence Otway, in charge of the operation, decided to proceed regardless, as the emplacement had to be destroyed by 06:00 to prevent it firing on the invasion fleet and the troops arriving on Sword Beach.
In the Battle of Merville Gun Battery, Allied forces disabled the guns with plastic explosives at a cost of 75 casualties.
The emplacement was found to contain 75 mm guns rather than the expected 150 mm heavy coastal artillery.
Otway's remaining force withdrew with the assistance of a few members of the 1st Canadian Parachute Battalion.

With this action, the last of the D-Day goals of the British 6th Airborne Division was achieved.
They were reinforced at 12:00 by commandos of the 1st Special Service Brigade, who landed on Sword Beach, and by the 6th Airlanding Brigade, who arrived in gliders at 21:00 in Operation Mallard.
