# 3rd U.S. Dragoons

The 3rd U.S. Regiment of Dragoons was a United States Army Dragoon regiment raised for one year of service in the Mexican–American War, by Congress on February 11, 1847. It was led by Colonel Edward G. W. Butler, who was appointed from Louisiana.

## Service Record

The 3rd Regiment of Dragoons was assigned to the expedition to Central Mexico, landing near Vera Cruz with Major General Winfield Scott's army and participating in the Siege of Vera Cruz, Battle of Churubusco and the Battle of Molino del Rey. The Third Dragoons took part in General Joseph Lane's pursuit of General Santa Anna in January 1848, and Lane's campaign against the guerrilla forces of Joaquín Rea at the action of Atlixco and of Padre Jarauta in late February 1848.
Major William H. Polk and a portion of Lane's forces engaged and defeated the Jarauta guerrillas in the action of Sequalteplan at Zacualtipan on February 25, 1848. In late May 1848, two companies under Polk's command escorted an American delegation to Querétaro, where the two countries exchanged official ratifications of the Treaty of Guadalupe Hidalgo, bringing the war to an end.
At the end of the war the regiment was disbanded.
