 It was under command of 80 AA Bde, initially responsible for covering 3rd Canadian Division at Juno and 3rd British Division at Sword, later extended to include the port of Ouistreham and the Orne and Caen canal bridges.Over succeeding days the battery brought more lights into action (16 by D + 4), but engagements were difficult because of the low cloud, the haphazard directions from which raiders approached, and their use of 'Window' to interfere with searchlight control (SLC) radar.The S/L sites were also subject to occasional shelling and bombing, causing some casualties.
