The Aftermath and Useful Resources
1st November 1940 - 10th May 1941
With the battle now over and the Luftwaffe unable to overcome the Royal Air Force and daylight attacks proving costly in both aircrew and aircraft the Luftwaffe would turn to night operations targeting cities with the intention to weaken civilian morale as a continuation of the Blitz. This would also see the rise of a new tactic adopted by the Germans of attacking cities on consecutive nights.
During the six months that followed the UK would suffer 135 major or heavy attacks with London being targeted the most, suffering a particularly devastating attack on the 29th December 1940, then Liverpool and Birmingham. Wherever there were factories vital to Britain's war industry the Luftwaffe would attack those cities, including Manchester with its A V Roe factory, Sheffield with its armament factories, Cardiff and its docks were bombed as Hull's, the industrial area of Clydebank and Glasgow and the docks and shipyard at Belfast also come under attack.
One of the worst raids of the Blitz occurred on the 14th November 1940 when the Luftwaffe launched Operation Mondscheinsonate (Operation Moonlight Sonata) targeting Coventry. On that night 568 people were killed and the Cathedral destroyed when 437 aircraft bombed the city. This would lead to a new word by the Germans "to coventrieren" (to Coventrate). The 23rd saw Southampton attacked heavily for the first time as well. November would also see Air Marshal Sir W. Sholto Douglas replace Hugh Dowding as Commander-in-Chief of Fighter Command on the 25th. Four days later on the 29th November Liverpool was attacked again and 166 people died when the shelter at Edge Hill Training Centre received a direct hit from a parachute mine, whilst former Prime Minister Neville Chamberlin had died at the age of 71 on the 9th November.
December 1940 would see No. 66 Squadron perform the first 'Rhubarb' fighter sweep over Europe on the 20th as Fighter Command started to go on the offensive.
One of the last major bombing raids of this period was on the 10th May 1941 when London was attacked by over 500 aircraft with 1,486 people killed. When the Blitz officially ended five days later on the 16th May it brought to an end 8 months and 10 days of attacks which saw 43,500 people lose their lives. Although Adolf Hitler turned his attention to the invasion of the Soviet Union this wasn't the end of attacks on the UK as over the coming months and years the Luftwaffe would return.
