What happened March 1937 AD in Spain

A similar Nationalist offensive, the Battle of Guadalajara, was a more significant defeat for Franco and his armies. This was the only publicized Republican victory of the war. Franco used Italian troops and blitzkrieg tactics; while many strategists blamed Franco for the rightists' defeat, the Germans believed it was the former at fault for the Nationalists' 5,000 casualties and loss of valuable equipment.

The "War in the North" began in mid-March, with the Biscay Campaign. The Basques suffered most from the lack of a suitable air force.
