Spanish Civil War: Military Evolution and Final Collapse
The Spanish Civil War: Military Evolution and Key Phases
Early War: Militia Formation and Initial Strategies (Until November 1936)
The initial phase of the Spanish Civil War could be described as a war of columns or colonial-style warfare, characterized by small, highly mobile units composed of various arms. This strategy formed the basis of the war until at least November 1936. In early August, the Republic declared the army dissolved and attempted to create a new force based on volunteer battalions. This marked the era of the militias, recruited from political organizations and unions. Various provisions in late September and October accelerated the militarization of these militias, laying the groundwork for a Regular People's Army based on mixed brigades.
Initial Nationalist Advances and Command Centers
In the initial months, the war was clearly unfavorable to the Republic. Navarra and Seville served as the two primary centers for the dissemination of large rebel columns, acting as the field commands for Mola and Franco, respectively.
The Battle of the Ebro: The Republic's Last Stand
In the Battle of the Ebro, the Republican army launched its last major offensive to try and salvage the situation. They crossed the Ebro in July and held their positions despite intense fire from Franco's troops. However, the breaching of dams, the withdrawal of International Brigades volunteers, and the capitulation of France and Great Britain to Hitler (the Munich Pact), which effectively closed the French border, forced Republican forces to withdraw and concede the Battle of the Ebro as lost.
Phase 4: December 1938 to April 1, 1939 – The Final Collapse
Ultimately, Catalonia and Madrid fell to the Nationalist forces.
Post-Ebro: Nationalist Advance and Republican Division
After the Battle of the Ebro, Nationalist troops advanced with little opposition, entering Barcelona. Despite Negrín's efforts to approve a plan of resistance, Franco's government was recognized by France and Britain. Furthermore, Republican forces were now divided between those who supported continued resistance and those who believed that prolonging the war was an act of cruelty and preferred to negotiate. Franco rejected any negotiation and instead enacted a Law of Political Responsibilities, which imposed harsh conditions on those who had collaborated with the Republic. With the French border closed, Republican forces were confined to the remaining parts of the Central and Southeast regions.
The Fall of Madrid and End of the War
In Madrid, the Republic crumbled due to the division between Communists (who supported resistance until the end) and the forces of Colonel Casado (who sought to surrender). The war officially ended on April 1, 1939.
