This room covers the events that unfolded after the Cry of Dolores and during the time Father Hidalgo took up arms. It was a period in which he transformed from priest to revolutionary leader, until his execution in Chihuahua on July 30, 1811.

Among the objects on display is an oil painting titled "Father Hidalgo with the Patrol", painted in 1900 by Anastasio Vargas; the desk where Hidalgo signed an ultimatum to Intendant Riaño on September 28, 1810; reproductions of banners used in the early phase of the armed struggle; and a selection of weapons from the period, including muskets, rifles, machetes, farming tools, and slingshots.
