In 1836, many legendary Texans gave their life during the 13 day siege at the Alamo. One of those was William Travis.

In support of independence from Mexico, a gentlemen provided lumber for platforms for the cannons needed for defense. He was a San Antonio business owner named Eugenio Navarro. He provided Travis with the information that a Mexican Army was planning to attack the Alamo according to a fact sheet from Heritage Auction's website.

Travis wrote a letter promising payment for the lumber used or the return of any undamaged wood. Not many artifacts survived the attack but this letter was one of the few.

It reads, "There is now in use at the Alamo Six hundred & Eighty two feet of Walnut Scantling as platforms for the cannon belonging to Eugenio Navarro which are to be paid for, if not returned at their first value-Bexar February 21st 1836.
W. Barret Travis"
