He settled in Bastrop and in September joined Capt. Robert M. Coleman's company of volunteers that marched from Bastrop to the relief of Gonzales (see GONZALES, BATTLE OF). On December 20, 1835, he signed the Goliad Declaration of Independence. He enlisted in the Texas army on February 28, 1836, and at San Jacinto served in Capt. Jesse Billingsley's Company C-also known as the "Mina Volunteers"-of Col. Edward Burleson's First Regiment, Texas Volunteers.

After his discharge Dennis moved to Matagorda County, where he was elected clerk of the county court in February 1837. He was reelected on February 7, 1839. In 1841 he was elected to represent Matagorda County in the House of Representatives of the Sixth Congress of the republic. There he served on the Naval Affairs Committee. Dennis is said to have been elected captain of several volunteer companies that saw action against the Indians on the western frontier and to have served at the battle of Plum Creek, in the repulse of Rafael Vásquez and Adrián Woll,qqv and on the Somervell expedition. He served as a private in Capt. Albert C. Horton's company in Col. Clark L. Owen's regiment of volunteers from March 6 through April 13, 1842. On February 3, 1845, he was elected sheriff of Matagorda County. By 1850, in partnership with surveyor Joshua Threadgill, he was well known as a horse and general stock raiser; his property was valued at $5,000.
After leaving Matagorda County about 1852 he lived for a time in Gonzales County, where, on September 24, 1852, he was appointed to the county Democratic committee. He is said to have resided in Rockport for some twenty years before moving to Karnes and Wilson counties, where he was engaged in stock raising.
