During the Mexican–American War, Halleck, a graduate of the United States Military Academy, spent several months in California constructing fortifications, then was first exposed to combat on November 11, 1847, during William Shubrick's capture of the port of Mazatlán. Halleck served as lieutenant governor of the occupied city. He was then transferred north to serve under General Bennet Riley, the governor general of the California Territory, and was soon appointed military secretary of state, a position which made him the governor's representative at the 1849 convention in Monterey where the California state constitution was written.
