1st Special Service Brigade, under the command of Brigadier Lord Lovat, was piped ashore in the second wave led by No 4 Commando with the two French Troops first, as agreed amongst themselves. The British and French personnel of No.4 Commando had separate targets in Ouistreham – the French a blockhouse and the Casino, the British two batteries which overlooked the beach.

The blockhouse proved too strong for the Commandos' PIAT (Projector Infantry Anti Tank) weapons, but the Casino was taken with the aid of a Centaur tank. The British Commandos achieved both battery objectives only to find that the guns had been removed. Leaving the mopping-up to the infantry, the Commandos withdrew from Ouistreham to join other units in their brigade, moving inland to join-up with the 6th Airborne Division.
