Hundreds of civilians were killed and hundreds more injured on 26 April 1937 when planes from the German Condor Legion, operating alongside aircraft from fascist Italy, spent hours bombing Guernica on market day. Adolf Hitler had loaned the Luftwaffe unit to Gen Francisco Franco's nationalist forces to help them in their coup against the republican government, and to allow Nazi Germany's pilots to practise the blitzkrieg tactics they would later use in the second world war.
