Medina de Rioseco
After the recent setbacks suffered by the comuneros, Padilla realized that they needed a victory to raise morale. He decided to take Torrelobatón and its castle. Torrelobatón was a stronghold halfway between Tordesillas and Medina de Rioseco, and was very close to Valladolid. Taking it would grant the rebels an excellent fortress for launching military operations and remove a threat on Valladolid.
