David Emanuel Twiggs (February 14, 1790 – July 15, 1862), born in Georgia, was a career army officer, serving during the War of 1812, the Black Hawk War, and Mexican–American War. As commander of the U.S. Army's Department of Texas when the American Civil War broke out, he surrendered his entire command to Confederate commissioners, with facilities, armaments and other supplies valued at $1.6 million. Dismissed from the US Army and described as a traitor, he was commissioned as a general of the Confederate States Army in 1861. But, recognizing he was in poor health, he quickly resigned his commission that year. He was the oldest Confederate general to serve, even briefly, in the Civil War.
