The Segovia Offensive was a Republican diversionary offensive which took place between 31 May and 6 June 1937, during the Spanish Civil War. The main goal of the offensive was to occupy Segovia and divert Nationalist forces from their advance on Bilbao. After a brief initial advance the offensive failed due to Nationalist air superiority.
In April 1937, the Nationalists started an offensive against the Republican held, Biscay Province, and, by the end of May, the Navarrese troops had reached the eastern side of Bilbao's defenses. The Republican government then decided to launch two diversionary offensives on the Aragon and Madrid fronts in order to divert Nationalist troops.
The Republican Army had three divisions in the Sierra de Guadarrama: Galan's 34th, General Walther's 35th and Duran's 69th divisions (according to Thomas, the commander of the 69th division was Luis Barceló), under the command of the Colonel Domingo Moriones, supported by artillery and a company of T-26 tanks.
On May 31 the Republicans started the attack in the Sierra de Guadarrama with a heavy bombardment of the Nationalist positions, broke the Nationalist lines at San Ildefonso and the same day the 69th division occupied Cruz de la Gallega and advance towards Cabeza Grande, threatening the Segovia Road, although the XIV International Brigade suffered appalling casualties. The Republican advance reached La Granja, but on June 1, the Nationalists started a counteroffensive with the General Varela's division, the reinforcements brought from the Madrid front by Barrón and heavy air support. The Nationalists recovered Cabeza Grande and threatened the Republican troops. On June 6, Moriones ordered the Republican troops to retreat to their start lines. The Republicans had lost 3,000 men, among them 1,000 members of the XIV International Brigade.
