the area within two weeks. However, the initial results were disappointing, and after a fortnight AA Command changed its tactics. Firstly, mobile HAA guns were replaced with static installations that could traverse more quickly to track the fast-moving targets. These were emplaced on temporary 'Pile platforms' named after the Commander-in-Chief of AA Command, Gen Sir Frederick 'Tim' Pile. Secondly, the HAA gun belt was moved to the coast and interlaced with LAA guns to hit the missiles out to sea. This new belt was divided into six brigade sectors, with 43 AA Bde HQ taking charge of one sector, with 183rd (M) HAA and 143rd LAA Rgts under command. The whole process involved the movement of hundreds of guns and vehicles and thousands of servicemen and women, but a new 8-gun site could be established in 48 hours. The guns were constantly in action, but success rate against the 'Divers' steadily improved, until over 50 per cent of incoming missiles were destroyed by gunfire or fighter aircraft. This phase of Operation Diver ended in September after the V-1 launch sites in Northern France had been overrun by 21st Army Group.
