Thanks to a French gendarme giving the commandos detailed information of the German positions, an attack, led by the French was implemented.

They soon outflanked the German defences and seized the village of Colleville-Montgomery.

He had personally promised the 6th. Airborne's commander, Major General Gale, that he would be there "Sharp at Noon"
The recognition signal was to be the sound of his personal piper, Bill Millen playing, Blue Bonnets Over the Border.
He in fact reached the bridge at 12:03 with his piper playing beside him.
