The Nationalists decided to redeploy their forces and continued their offensive against Asturias, the last piece of Republican-held territory in northern Spain.

On 29 August, the Sovereign Council of Asturias, led by Belarmino Tomas, assumed all military and civil powers and appointed Colonel Adolfo Prada as commander of the Spanish Republican Army of the North.

[1] The Nationalist offensive was launched by General Fidel Dávila Arrondo's Army of the North with 80,000 men, which included José Solchaga's four Brigades of Navarre, Antonio Aranda's three divisions, and the Italian Corps of Volunteer Troops (CTV).

On 14 October, Arriondas fell and Colonel Agustín Muñoz Grandes managed to break the Republican front, entering Tama and advancing to Campo de Caso.

[6] On 17 October, the Sovereign Council of Asturias decided to start the evacuation, but the Legion Condor sank the Republican destroyer Ciscar, and the Nationalist fleet blocked the Asturian harbours.

Only the senior officers managed to escape on gunboats and fishing vessels (Prada, Galán, Segundo Blanco, Belarmino Tomas).

[8] The Asturias Offensive marked the end of a Republican presence in northern Spain and Nationalist victory in the War in the North.
