Location
Cause → Event → Consequence
As part of the broader Nationalist War in the North campaign in 1937, Nationalist forces sought to advance into eastern Asturias and link up with columns moving from León, aiming to eliminate the last Republican-held territory in north-west Spain.
Between 6 and 22 September 1937, Republican forces defended El Mazucu and the surrounding mountains against a much larger Nationalist army. Despite being outnumbered sevenfold and subjected to what is considered among the first uses of carpet bombing against a military target, the defenders held out for weeks over extreme terrain before being overwhelmed.
The Nationalist forces, having broken through at El Mazucu, were able to link up with their columns advancing from León. This connection led directly to the fall of Gijón and the complete abandonment of Asturias, ending Republican resistance in north-west Spain.
