Briscoe emigrated to Texas, gained Mexican citizenship in 1833, then settled in
Anahuac, Texas, where he opened a store. He was among the local businessmen who protested the manner in which Mexican authorities collected import duties. He was jailed with
DeWitt Clinton Harris, catalyzing an armed confrontation led by
William B. Travis, the second of the Anahuac Disturbances. He volunteered on behalf of the Texian rebels at the
Battle of Concepción,
Siege of Bexar, and led Company A, Infantry Regulars at the decisive
Battle of San Jacinto. Briscoe was a delegate to the Texas
Convention of 1836. After Texas Independence, President
Sam Houston appointed him to serve as the first
Chief Justice of Harrisburg County, later renamed
Harris County, Texas. After his term ended in 1839, he retired from office and became a cattle dealer. In 1839, he planned a new railroad from town of
Harrisburg, Texas to the Brazos River. He hired workers to grade a roadbed and lay ties for about two miles before running short of capital. ==Personal life==
