Medina de Rioseco
In late November 1520, both armies took positions between Medina de Rioseco and Tordesillas, and a confrontation was inevitable. With Pedro Girón in command, the army of the comuneros advanced on Medina de Rioseco, following the orders of the Junta. Girón established his headquarters in Villabrágima, a town merely from the royalist army. The royalists occupied nearby villages to cut communication lines back to other comuneros.
