20 Apr 1937

- In Spain, two Anarchist battalions, who were dissatisfied with their movement's representation in the Republican Government, went on strike and pulled out, leaving a 15-mile gap in the front line in front of the little town of Marquina directly east of Guernica. Von Richthofen, commanding the German Condor Legion, quickly realised that if the gap was exploited, the Republican Forces in the area would be forced to withdraw and could be trapped if the single bridge at Guernica was destroyed by bombing. ww2dbase [The Spanish Civil War | AC]
