The Sec. of War dismisses Gen Twiggs for surrendering miltary posts in Texas
http://www.sonofthesouth.net/mexican-war/pictures/general-david-twiggs.jpg
After the Mexican-American War, Twiggs was appointed brevet major general and commanded the Department of Texas. He was in this command when the Civil War broke out. Twiggs's command included about 20% of the U.S. Army guarding the border of the U.S. and Mexico. As the states began to secede, Twiggs met with a trio of Confederate commissioners, including Philip N. Luckett and Samuel A. Maverick, and surrendered his entire command to them. At the time of his surrender, Twiggs was in San Antonio with approximately 200 Union soldiers, the remainder of his troops scattered along the border between the United States and Mexico. 2,000 Secessionist militia entered the city, intent on capturing the Union arsenal there. Outnumbered five to one, Twiggs surrendered on February 19, 1861.
Twiggs subsequently was dismissed from the U.S. Army for treason and accepted a commission as a major general from the Confederate States. He was appointed to command the Confederate Department of Louisiana, but his advanced age and health kept him from pursuing an active command. He was replaced by Maj. Gen. Mansfield Lovell in the command of New Orleans.[1] and retired on October 11, 1861. He died of pneumonia in Augusta, Georgia, and is buried at "Good Hope".
