On this day in 1942, in retaliation for the British raid on Lubeck, German bombers strike Exeter and later Bath, Norwick, York, and other "medieval-city centres." Almost 1,000 English civilians are killed in the bombing attacks nicknamed "Baedeker Raids."
On March 28 of the same year, 234 British bombers struck the German port of Lubeck, an industrial town of only "moderate importance." The attack was ordered (according to Sir Arthur Harris, head of British Bomber Command) as more of a morale booster for British flyers than anything else, but the destruction wreaked on Lubeck was significant: Two thousand buildings were totaled, 312 German civilians were killed, and 15,000 Germans were left homeless.
As an act of reprisal, the Germans attacked cathedral cities of great historical significance. The 15th-century Guildhall, in York, as an example, was destroyed. The Germans called their air attacks "Baedeker Raids," named for the German publishing company famous for guidebooks popular with tourists. The Luftwaffe vowed to bomb every building in Britain that the Baedeker guide had awarded "three stars."
