The Lone Star Reloaded Series by Drew McGunn

After the explosion, Will didn’t expect to wake up again, especially in the past. Alive is good. Except he finds himself at the Alamo in 1836 in the body of another man doomed to die. If history repeats itself, Santa Anna is coming soon and the Alamo will fall, along with himself and 189 others. In a race against time itself, Will uses his knowledge of the future to change the past. He will use every means necessary, even if it means abandoning the fort. He is determined to forget the Alamo!

Will defied history and saved the Alamo. However, before the celebration even gets started, proof of a Comanche uprising the likes of which have never been seen before force Will to scramble for a solution to keep the frontier from going up in flames. This time, he doesn't know what the future holds. But he might be able to find an invention to give his troops a fighting chance, assuming there's enough time and his enemies don't kill him or remove him from command.

Six years after being stranded in the past, Will has survived the Alamo, brokered peace with the Comanche, and found love. Now he faces his greatest challenge yet. Determined to enforce a treaty's boundary, the president orders Will and the army of the Republic of Texas to annex everything north of the Rio Grande, including Santa Fe. But the dictator, Santa Anna has returned to power in Mexico and he wants his country back - all of it... moreSix years after being stranded in the past, Will has survived the Alamo, brokered peace with the Comanche, and found love.
