Lindsay S. Hagler, soldier and legislator, was born in Wilkes County, North Carolina, and immigrated to Texas. He joined the Army of the Republic of Texas as a captain on June 17, 1836, and served until September 30. He rejoined the army with the same rank on December 24 and continued in service until December 15, 1837. He spent part of this time recruiting in the United States. For his service he received a 1,280-acre bounty donation in Atascosa County. In 1839 and 1840 he fought with the federalist general Antonio Canales in the Mexican civil war. In 1840 Hagler was elected to represent San Patricio County in the House of Representatives of the Fifth Congress of the Republic of Texas. When he was defeated in the election of 1841, his contesting of the apparent victory of Alanson Ferguson resulted in the seating of Simeon Jones. Hagler was reelected to the House of Representatives of the Seventh and Eighth congresses and served from November 14, 1842, until February 5, 1844. He also served as a private in Capt. A. T. Miles's San Patricio County Minute Man company from August 10 through August 28, 1841, on a campaign to the lower end of Padre Island that, on August 17, resulted in the capture of a Mexican captain and nine privates. These men were exchanged at Matamoros for an equal number of Texan prisoners. The Texans specifically requested the exchange of Philip Dimmitt in the cartel, but by that time Dimmitt had committed suicide in prospect of an extended captivity. Hagler was elected surveyor of Goliad County on October 13, 1845, and county clerk twelve days later. In 1846 he was killed in an affray on the streets of Goliad by a man named Pool.
