Fort Aubrey.—About the close of the Civil war a number of volunteer regiments were ordered to the western frontier to quell Indian uprisings, and these men erected several temporary fortifications at various points along the border of civilization. One of these was Fort Aubrey, which was located on section 23, township 24, range 40 west, on Spring creek, about two and a half miles from its mouth, not far from the present village of Mayline in Hamilton county. It was built by Companies D and F, Forty-eighth Wisconsin infantry, under the command of Capt. Adolph Whitman. The exact date of its establishment is not certain, but it was late in August or early in Sept., 1865. It was abandoned on April 15, 1866.
