The Rosal column reached Navamorcuende and fought in the Tiétar Valley. On 20 August it stayed on this front until it sank with the taking of Talavera de la Reina on 6 September. The column suffered numerous casualties, of the thousand fighters that departed from Madrid, only 250 returned. Among the dead was Teodoro Mora, who was replaced as confederal delegate by Cipriano Mera. Reinforcements were sent to them from Madrid. With the reinforcements that the column received, mostly improvised and poorly organized, they organized the following battalions: "Francisco Ferrer", "Orobón Fernández", "Manuel Pau", "Noi del Sucre", "Mikhail Bakunin" and "Rafael Casado". Manuel Pau and Rafael Casado were the first two battalions to die at Paredes de Buitrago. Several centuries of the Land and Freedom Column, which came from Catalonia to reinforce the defense of Madrid, were also sent to them. The Rosal column was finally removed from the front on 15 September, with numerous casualties.
