After hearing news of the capture of insurgent commanders in Acatita de Baján, López Rayón left Coahuila on 26 March and made way with his forces to Zacatecas. His march to Zacatecas was pursued by the Royalist army of José Manuel Ochoa who López Rayón defeated at the Battle of Puerto de Piñones. The victory was not decisive and the Royalist army continued to harass the insurgents until they were defeated again at Zacatecas on 15 April, 1811. López Rayón took the town of Zacatecas and used it as an industrial base to produce artillery, gunpowder, and uniforms for his soldiers.
