Bombing of Guernica
On 26 April 1937, the Basque town of Guernica (Gernika in Basque) was aerially bombed during the Spanish Civil War. It was carried out at the behest of Francisco Franco's rebel Nationalist faction by its allies, the Nazi German Luftwaffe's Condor Legion and the Fascist Italian Aviazione Legionaria, under the code name Operation Rügen.
