The Bloodless Capture of Tucson: Mexican Garrison Withdraws as Mormon Battalion Enters Peacefully (December 16, 1846)

On December 16, 1846, the Mormon Battalion marched toward Tucson — then a Mexican presidio garrisoned by Captain Antonio Comaduran and a force of approximately 200 soldiers.

It was a moment of genuine military danger. The United States was at war with Mexico. A garrison occupied the town. The two forces were on opposite sides of that war.

Brigham Young had prophesied the Battalion would never face human enemies in battle. That prophecy was now being tested against armed Mexican soldiers dug into a fortified position.

Comaduran chose to withdraw.

Rather than defend the presidio, the Mexican commander evacuated his force before the Battalion arrived. The Mormon soldiers entered Tucson without firing a single shot. The population remained. The Battalion obtained supplies from local citizens and departed peacefully two days later.

The Church History timeline records it plainly: 'The battalion reaches Tucson and nearly engages in battle with a Mexican garrison.' The word 'nearly' tells the whole story. They came close enough that historical records acknowledge the potential battle — and then nothing happened.

For the men of the Battalion, who had been marching for months under a specific prophecy that their weapons would not be turned against other men, the peaceful entry into a garrisoned enemy town was one more evidence that the hand of God was with them.
