Play it Again

A terrorist group has somehow gotten a hold of an atomic bomb and smuggled it into the United States. Their plan is to destroy a military base on US soil. Intelligence sources have issued a warning and a small team of army soldiers is sent out and happens to find it. While investigating the bomb, it is set off, but instead of dying, they are sent back to 1835. A short time before the Battle of the Alamo. They must now decide what their next step will be. Should they let history play out again or change the tune?
