The Girl I Left Behind Me (1915)

At a lonely army post in the West, a dance marking the engagement announcement of the general's daughter to Lieutenant Hawkesworth is interrupted when word arrives that the hostile Blackfoot tribe is on the warpath. Hawkesworth and the rival for his fiancee's affection, Lieutenant Parlow, are sent with the regiment to repress the uprising. Parlow turns out to be a coward at a critical moment, and after the regiment is routed, he blames Hawkesworth for the defeat. The general then orders his daughter to break her engagement and become Parlow's fiancee. The Blackfeet surround the fort, and Hawkesworth makes a daring ride through them to a neighboring fort. He brings the U.S. 6th Cavalry, who subdue the Blackfeet. Parlow's cowardice is then learned, and it is also revealed that earlier he eloped with the wife of an officer and then abandoned her. Hawkesworth and the general's daughter become married.
