SAN ANTONIO – With a little muscle and a lot of patience, 1,600 pounds of history are now back at the Alamo where they belong.

Two very special cannons used in the 1836 battle of the Alamo were delivered Texas style - in the back of a pickup truck.　

"When you go to most battle fields, you'll see cannons that have been re-placed there years afterwards. But these cannons were actually used at the Battle of the Alamo," said Alamo Curator and Historian Bruce Winders.　

The cannons were taken from the Alamo ground three months ago for a trip to the Texas A&M Conservation Research Lab in College Station. The cannon were studied and better preserved. The trip even revealed some deep secrets.

"One of them bore markings of where it was made so now we know more about it. And the other one had a cannon ball in it that was probably loaded during the battle and never fired," said Bryan Preston with the Texas General Land Office. 　

The Texas General Land Office said this is the first of many similar sights, as the office works to better preserve what is left at this battle site.

"You will see overtime the battle field change. It will look not like a park, but a battle field like it did in 1836. You'll see the church preserved," said Preston.　

Two more cannons are now in the lab to undergo preservation. All seven will eventually be treated.

"It's very cool that somebody can come here and put their hand on a cannon barrel knowing that an Alamo defender did the same thing. Your hand might be in the exact same spot that William B. Travis was in," said Winders.
