The "1st Texas" refers to the 1st Texas Infantry Regiment, a unit that served in the Confederate Army during the American Civil War. Formed in 1861, it was composed primarily of volunteers from Texas and played a significant role in various battles throughout the war, including the Battle of Galveston and the Siege of Vicksburg. The regiment was known for its bravery and commitment, often fighting alongside other Confederate units. After the war, many of its members returned to Texas, contributing to the state's post-war recovery and development. The legacy of the 1st Texas remains a part of Texas history and military heritage.
