Hidalgo headed to Valladolid (now Morelia), which was captured with little opposition. While the Insurgent Army was, by then, over 60,000 strong, it was mostly formed of poorly armed men with arrows, sticks and tillage tools – it had a few guns, which had been taken from Spanish stocks. In Aculco, the Royal Spanish forces under the command of Felix Maria Calleja, Count of Calderón, and Don Manuel de Flon (and comprising 200 infantrymen, 500 cavalry and 12 cannons) defeated the insurgents, who lost many men as well as the artillery they had obtained at Battle of Monte de las Cruces. On 29 November 1810, Hidalgo entered Guadalajara, the capital of Nueva Galicia, where he organized his government and the Insurgent Army; he also issued a decree abolishing slavery. At Calderon Bridge (Puente de Calderón) near the city of Guadalajara Jalisco, insurgents held a hard-fought battle with the royalists. During the fierce fighting, one of the insurgents' ammunition wagons exploded, which led to their defeat. The insurgents lost all their artillery, much of their equipment and the lives of many men. At the Wells of Baján (Norias de Baján) near Monclova, Coahuila, a former royalist named Ignacio Elizondo, who had joined the insurgent cause, betrayed them and seized Miguel Hidalgo y Costilla, Ignacio Allende, Juan Aldama, José Mariano Jiménez and the rest of the entourage. They were brought to the city of Chihuahua where they were tried by a military court and executed by firing squad on 30 July 1811. Hidalgo's death resulted in a political vacuum for the insurgents until 1812. Meanwhile, the royalist military commander, General Félix María Calleja, continued to pursue rebel troops. The fighting evolved into guerrilla warfare. The next major rebel leader was the priest José María Morelos y Pavón, who had formerly led the insurgent movement alongside Hidalgo. Morelos fortified the port of Acapulco and took the city of Chilpancingo. Along the way, Morelos, was joined by Leonardo Bravo, his son Nicholas and his brothers Max, Victor and Miguel Bravo. Morelos conducted several campaigns in the south, managing to conquer much of the region as he gave orders to the insurgents to promote the writing of the first constitution for the new Mexican nation: the Constitution of Apatzingan, which was drafted in 1814. In 1815, Morelos was apprehended and executed by firing squad. His death concluded the second phase of the Mexican War for
