Mexican dragoons dispatched to disarm settlers at Gonzales in Mexican Texas encountered stiff resistance from a Texian militia at the Battle of Gonzales, the first armed engagement of the Texas Revolution.

Dragoons were originally a class of mounted infantry, who used horses for mobility, but dismounted to fight on foot. From the early 17th century onward, dragoons were increasingly also employed as conventional cavalry and trained for combat with swords and firearms from horseback. While their use goes back to the late 16th century, dragoon regiments were established in most European armies during the 17th and early 18th centuries; they provided greater mobility than regular infantry but were far less expensive than cavalry.

Gonzales is a city in the U.S. state of Texas, with a population of 7,165 at the 2020 census. It is the county seat of Gonzales County.

Texians were Anglo-American immigrants to Mexican Texas and, later, citizens of the Republic of Texas. Today, the term is used to identify early Anglo settlers of Texas, especially those who supported the Texas Revolution. Mexican settlers of that era are referred to as Tejanos, and American citizens of the modern State of Texas regardless of race and ethnicity are referred to as Texans.

The Battle of Gonzales was the first military engagement of the Texas Revolution. It was fought near Gonzales, Texas, on October 2, 1835, between rebellious Texian settlers and a detachment of Mexican army soldiers.

The Texas Revolution was a rebellion of colonists from the United States and Tejanos against the centralist government of Mexico in the Mexican state of Coahuila y Tejas. Although the uprising was part of a larger one, the Mexican Federalist War, that included other provinces opposed to the regime of President Antonio López de Santa Anna, the Mexican government believed the United States had instigated the Texas insurrection with the goal of annexation. The Mexican Congress passed the Tornel Decree, declaring that any foreigners fighting against Mexican troops "will be deemed pirates and dealt with as such, being citizens of no nation presently at war with the Republic and fighting under no recognized flag". Only the province of Texas succeeded in breaking with Mexico, establishing the Republic of Texas. It was eventually annexed by the United States about a decade later.
