The Land and Freedom Column was a militia column organized by the CNT-FAI from the regions of Berguedà and Bages as well as from Barcelona. The column was sent to the Central front in mid-September 1936 to reinforce the republican line against a nationalist force that was entering Talavera de la Reina and besieging Toledo, thereby threatening Madrid. It had around 1,500 militiamen in its beginnings, participating in the fronts of the Sierra de Gredos and Sierra de Albarracín. The column integrated into the Rosal Column and later fought on the Serra de Montsant front. After the militarization that occurred in the spring of 1937, the column became the 153rd Mixed Brigade.
