5. Guernica- Facts
The town of Guernica is situated 30 kilometers east of Bilbao, in Spain.
On 26th April 1937, Guernica was bombed by the German Condor Legion. As it was a market day the town was crowded.
The town was first struck by explosive bombs and then by incendiaries. As people fled from their homes they were machine-gunned by fighter planes.
The three hour raid completely destroyed the town. It is estimated that 1,685 people were killed and 900 injured in the attack out of a population of 7000.
What effect did the development of bombers and the casualties at Guernica have on the British Government?
