The Guns of Fort Petticoat is a 1957 American Western film produced by Harry Joe Brown and Audie Murphy for Brown-Murphy Pictures.

The fictional story tells the tale of an Army deserter training a disparate group of women to become Indian fighters climaxing in a Battle of the Alamo-type action.

Hewitt not only disagrees with the punishment of the Indians but realizes they will use the attack as an excuse to unite and spread terror throughout the Southwest, including his hometown in Texas, which has sent most of its men to fight for the Confederacy.

The "blue-belly traitor" Hewitt and the petticoat brigade are deserted by the only remaining man; they fight off scavengers and Comanches as they struggle to build trust and work together during the ensuing attacks.

As Hewitt is being renounced as a deserter and a liar for his most fantastic story of helping to rescue the women in Texas and training them to fight off Comanches, Col. Chivington's commanding general happens to enter the trial room.
