The column first named itself the "Red and Black" however when they arrived in Barcelona they found that there was already another column with the same name. So they changed it to ""Land and Freedom"", which was a classic motto of Spanish anarchism. In Barcelona several more centuries were added to the column, which received military training in the barracks controlled by the "CNT-FAI". On September 7 they departed for Madrid by train. They were sent as Catalan aid to the central front, the "Freedom" column of the PSUC and the UGT was also sent in October and the Durruti Column in November. In Madrid the column had about 1,500 militiamen, since several centuries with local militiamen had also attached to it. The column had an artillery battery with two 105mm guns, named Sacco and Vanzetti, in honor of two Italian-American anarchists executed in 1927.
