With the outbreak of the Civil War, however, Lesuer had, in September 1861, raised a company of cavalry, the "San Andres Light Horse Company," in Milam County for service in the Confederate army. Lesuer declined his seat in the legislature, opting instead to become a captain in the Fourth Texas Cavalry Regiment, when his company was incorporated into that unit at San Antonio in late September. He was commissioned as major on April 14, 1863. Lesuer received promotion to lieutenant colonel prior to the surrender of his unit on May 26, 1865. Following the war, he returned to Central Texas and resumed his leadership in the community. He served as Milam County commissioner during 1866 and 1869. In 1878 he was elected treasurer of Williamson County. Lesuer died on September 17, 1889, in Williamson County and was buried at the Presbyterian Cemetery in Georgetown, Texas.
