William Capers Simmons, soldier in the battle of San Jacinto, was born in 1789 and immigrated to Bastrop County in April 1835 and received one-third of a league. He enlisted in the Revolutionary Army on October 2, 1835, and served until December 14, 1835; he may have fought at the siege of Bexar. He reenlisted on February 28, 1836, and although the General Council commissioned Simmons a second lieutenant in the artillery corps of the regular army on March 10, 1836, he fought at the battle of San Jacinto as a private in Capt. Jesse Billingsley's Company C-the "Mina Volunteers"-of Col. Edward Burleson's First Regiment, Texas Volunteers. He was discharged on May 28, 1836. On February 2, 1840, when Leander Calvin Cunningham resigned as justice of the peace of Bastrop County, Simmons and his neighbors petitioned President Mirabeau B. Lamar to appoint Greenleaf Fisk in his place. By 1840 Simmons owned 2,279 acres in Bastrop County. In 1853, he married to Mahala Perkins Blakey Boyce, a widow, and was a brother-in-law to Noah Smithwick. Simmons died in Bastrop County on January 19, 1874, and was buried in a family plot in Lawrence Chapel Cemetery in Williamson County. He was a member of the Texas Veterans Association.
