Today, or rather, early this morning, was the 70th anniversary of this event.
The 'Daily Telegraph' 'flashback' reproduction states that it had been London's longest air raid alert, with one or two planes at a time coming over for 6 hours, believed to be intended to keep the population awake and disrupt production. Very few bombs were dropped and London cinemas and theatres continued their programmes, and restaurants and dance halls stayed open. Berlin had an air raid alert, but according to local correspondents no planes or gunfire was heard.
What actually happened?
According to 'The Narrow Margin' bombs were dropped on Bournemouth and Coventry, and about 50 aircraft raided Plymouth; the decoy airfield for St Eval airfield in Cornwall was heavily bombed, and 6 other RAF airfields were attacked without effect. Wot - no Gillingham!?
'The Bomber Command War Diaries' state that 99 RAF bombers attacked Hannover, Leipzig, Leuna, and Nordhausen. 1 lost. 11 Whitleys attacked Turin and Milan. 2 lost.
