A fascinating discovery at the South Texas Archives on the campus of Texas A&M University-Kingsville has the attention of history buffs all over Texas.

What has so many people excited at the South Texas Archives are two documents from the 1850s, both found here and signed by the President of Mexico at the time, Santa Anna.

Juan Duran translated the documents for 3News and you heard right, the signature on the documents is from none other than Santa Anna himself, the man who ordered the killings of the men at the Alamo and at Goliad.

Daniel Thacker works at the South Texas Archives. He has been documenting the items that are in the Mifflin Kenedy Collection brought over to the University in wooden trunks. The two letters were sent to a man by the name of Paulino Bando spelling out his military commission and pay.

"These two letters would add to our body of knowledge that already serve as existing key conclusions that we've drawn about Santa Anna rather than providing a new revelation," TAMUK History Chair Shannon Baker said.

Researchers believe Santa Anna handed out the military commissions to try and tighten his stronghold on Mexico.

"One of the ways that Santa Anna tried to consolidate his power was to ally himself with certain interest groups being the military, and one of the ways to consolidate his power through the military was to give multiple promotions," Baker said.

No one knows how the two Santa Anna documents ended up in the hands of Mifflin Kenedy, but they do know why the South Texas ranching legend had it stored away. It is the pardon he received from President Andrew Johnson after siding with the south during the Civil War.
