Millard left his sons with foster parents in New Orleans and moved to Texas in 1835. He and his business partner Pulsifer opened a store in the settlement of Santa Anna, while the third partner, Huling, opened a store in
Zavala. The three of them decided to invest in land. They purchased of land between the settlements of
Tevis Bluff and Santa Anna. On that land they laid out the town of Beaumont, which Millard apparently named after Jefferson Beaumont. As a delegate to the Consultation of 1835 in San Felipe, he helped found the municipality of Jefferson, which later became Jefferson County. He was elected to the General Council of the Consultation, but resigned in order to accept a commission as a lieutenant colonel in the Texas revolutionary army.
Military career At first, Millard acted as a recruiting officer in
Nacogdoches, Texas. Then in 1836 he went with General
Sam Houston to a conference with the Cherokee people. A short time later he took command of a battalion and marched them to San Jacinto, where they fought on April 21, 1836, in the successful
battle against the Mexican forces under President
Antonio Lopez de Santa Anna. In his report of the battle, Houston wrote :''The artillery under the special command of Col. Geo. W. Hockley Inspector Gen'l. was placed on the right of the first Regiment; and four companies of Infantry under the command of Lieut Col. Henry Millard, sustained the artillery upon the right.'' After the battle, Houston gave Millard two pistols that had belonged to Santa Anna. Millard’s descendants later loaned them to the Republic of Texas Museum where they reside today.
Public service Millard acted as the chief justice of Jefferson County from 1838-1840. He was an alderman for the city of Beaumont and a justice of the peace. In 1842 he moved to
Galveston, Texas, to explore new business possibilities and became the tax assessor for Galveston County. == Death and legacy ==
