What did Stephen Austin do in the civil war?

Stephen Austin, known as the "Father of Texas," did not have a significant role in the Civil War, as he passed away in 1836, long before the conflict began in 1861. His contributions were primarily focused on the colonization of Texas and the independence movement from Mexico. Austin's legacy lies in his efforts to settle American families in Texas and his role in establishing it as an independent republic, rather than in military or political activities during the Civil War.
