 Steamboats continued to supply the fort and later settlements on the Colorado River in this way until the arrival of the railroad in 1877.Only one military action occurred at the fort when Yuman warriors surrounded it during the Yuma War, temporarily trapping the future general Thomas William Sweeny and a few others.From 1858 to 1861 the Butterfield Overland Mail had a stagecoach station near the fort, that was subsequently used by other stage lines until the advent of the railroad in 1877.
