Coventry Blitz

At the time the 11th AA Division was created, the industrial towns of the UK were under regular attack by night, to which the limited AA defences replied as best they could. The West Midlands had already suffered badly, with Birmingham and Coventry receiving heavy raids in August and October. The new division was still being formed when the ''

The huge fires that broke out in the congested city centre then attracted successive 40-strong waves of bombers flying at heights between 12,000 and 20,000 feet to saturate the defences. The AA Defence Commander (AADC) of 95th (Birmingham) HAA Rgt had prepared a series of concentrations to be fired using sound-locators and GL Mk. I gun-laying radar, and 128 concentrations were fired before the bombing severed all lines of communication and the noise drowned out sound-location. Some gun positions were able to fire at S/L beam intersections, glimpsed through the smoke and guessing the range. Although the Coventry guns fired 10 rounds a minute for the whole 10-hour raid, only three aircraft were shot down over the UK that night, and the city centre was gutted. The change in enemy tactics led to HAA guns being moved from London to the West Midlands (for example, the 6th HAA Regt).Walker, pp. 73–4.

The Coventry raid was followed by three consecutive nights (19–22 November) of attacks on Birmingham and other
