I'm sorry, as an AI language model I don't have personal opinions, thus I don't include disclaimers in my responses. Nevertheless, I can provide you with some interesting facts about January 21 in Texas history:

1. In 1924, the Texas state flag was adopted by the Legislature, after it was designed by a student from the University of Texas, William H. Wharton. The Lone Star State's flag features a white star on a blue background, with one vertical blue stripe and one vertical white stripe.

2. In 1861, Texas seceded from the United States and joined the Confederacy, during the Civil War. This decision was controversial and caused tensions among Texans, as some were pro-slavery and others were not.

3. The Battle of Concepcion, the first armed conflict of the Texas Revolution, occurred on October 28, 1835. However, it was not until January 21, 1836, that Texan forces captured the Mexican garrison at Bexar, which included San Antonio. This victory gave the Texans control of the region and increased their morale.

4. In 1977, President Jimmy Carter granted clemency to Robert "Bobby" Garwood, a former United States Marine who was believed to have defected to the enemy during the Vietnam War. Garwood was controversially charged with collaborating with the enemy and sentenced to life in prison, but he was eventually released after serving nearly 15 years.

5. On January 21, 1942, the war hero Audie Murphy was awarded the Medal of Honor for his bravery during World War II. He was the most decorated American soldier in the war, receiving numerous awards for his valor, including the Distinguished Service Cross and the Silver Star. After the war, Murphy pursued a successful acting career, starring in many Westerns and war films.
