Battle of El Mazuco - Aftermath

Aftermath

The defence of El Mazuco offered the hope of stemming the Nationalist advance until winter; if that had been achieved, then the course of the war would have been different. As it was, the attackers suffered a costly delay. The defenders regained their honour, battered in Santander, but also at great cost. The third-parties involved, notably the Condor Legion, learned many lessons which were later applied in the European theatre of the World War that followed.

The defence of El Mazuco also allowed the Republicans further west in Asturias a certain breathing space and a chance to regroup, but ultimately this made little difference. The Nationalists on the Eastern front soon joined up with the forces advancing from León at Infiesto, and closed in on Gijón. Gijón, the last republican stronghold in Northern Spain, fell on 21 October.
