March 2, 1863 the Texas Declaration of Independence was signed. It was quickly drafted by George C. Childress, Edward Conrad, James Gaines, Bailey Hardeman, and Collin McKinney. The battle at the Alamo was already taking place during this time. Fifty-nine delegates signed this document to separate from Mexico and become the Republic of Texas.
Sam Houston - governor of Tennessee at age 36; marshaled the army that won Texas independence; President of the Republic of Texas; U.S. Senator for the State of Texas and Governor of the State of Texas when the civil war began. Because of his ardent defense of the Union and refusal to swear allegiance to the Confederacy, he was deposed as governor in 1861 and vilified by Texans when he died of pneumonia in 1863. His last dying words to his wife Margaret, "Texas, Margaret ... Texas."
