The 70th Mixed Brigade was a unit of the Spanish Republican Army created during the Spanish Civil War. The unit intervened in the battles of Jarama, Guadalajara and Brunete. At the end of the war it played a role in the Casado coup. History The unit was created in Madrid on January 15, 1937, from the Free Spain Column of Alicante and Murcia; command of the new unit was handed over to Eusebio Sanz Asensio. The 70th Mixed Brigade was initially reserved for the Madrid Army Corps. On February 7, after having armed all its battalions, it was initially located in Madrid as a reserve to intervene in the Battle of Jarama. Attached to the 11th Division of Enrique Líster, the 70th MB took part in the fighting that developed around Pingarrón, between February 19 and 22; the unit lost half of its troops during these days, without being able to conquer the disputed position. Moved to the rear, it underwent a reorganization. The 70th MB received a new command, the largest of the militias Rafael Gutiérrez Caro, and was assigned to the 14th Division commanded by Cipriano Mera.
