FORT SIDNEY
As the Union Pacific Railroad was built across Western Nebraska in 1867, Sioux, Cheyenne, and Arapahoe opposition to its construction intensified. Survey and grading parties were attacked and workers killed. Horses and mules were run off with alarming frequency. In order to protect railroad employees and construction workers, increased military protection was necessary.

Army units from Fort Sedgwick (40 miles southwest of Sidney) and Fort D.A. Russell (at Cheyenne) provided escorts, station guards, and scouted along the route of the Union Pacific through the Lodgepole Creek valley.

In 1867, General C.C. Augur, commanding officer of the Department of the Platte, decided to establish a troop station at Sidney. Less than six months old, Sidney was a freight division point for the railroad, and the most important point between North Platte and Cheyenne. In December, Company E, 30th Infantry, under command of Captain Bernard P. Mimmack, arrived. Thus began the 26-year history of Fort Sidney.

The new post was first designated Sidney Barracks. The initial post site was just south of the railroad depot, in the present day main business district of town. For two years the troops lived here in tents with several temporary buildings erected for supplies and officer housing. In 1869 it was decided to move the embryonic post further from the depot. The new location was some 400 yards to the southeast, on the north bank of Lodgepole Creek. By 1870 buildings to house one company of cavalry had been constructed.

As was typical of frontier posts, the buildings were arranged around an open parade ground, with no fortifications. Sidney Barracks was never directly attacked by hostiles, although a minor raid occurred near the town in the spring of 1870. Soldiers from the post provided guards to nearby Potter and Lodgepole Stations, and spent much time scouting and patrolling for hostiles. In addition they pursued small bands that were reported to have committed depredations against travelers and setters in western Nebraska and northeastern Colorado.

In 1871 Fort Sedgwick was abandoned and moved to Sidney Barracks. That year new buildings were added to the post, including the extant Commanding Officer's quarters. Through the years, the garrisons at Sidney were increased from one to four and five companies of troops in the 1880's.

The discovery of gold in the Black Hills and the beginnings of the Sidney-Deadwood Trail brought a period of boom and excitement to the town. Between 1875 and 1880, thousands of gold seekers and millions of pounds of supplies and equipment traveled north from Sidney to the Black Hills. During the same period Sidney Barracks became a receiving depot for government freight to be shipped north to military posts and Indian agencies. Soldiers escorted the large bull trains on the trail.

Units stationed at the post were sent out for duty on the two major campaigns of 1876. Third Cavalry companies left Sidney for the Yellowstone Expedition in May. That October, two companies of the 23rd Infantry served with the Powder River Expedition. During the fall and winter of 1876-77, the famed Pawnee Scouts were stationed at the post. In 1878 the post became a staging area for army forces attempting to intercept the Cheyenne bands that broke from their Oklahoma reservations.

After the subjugation of the Sioux tribes to the reservations in western South Dakota, a number of frontier posts were abandoned. However, it was determined to continue the garrison at Sidney Barracks. In December, 1878, the post was redesigned Fort Sidney, reflecting its more permanent status.

The 1880's was a period of peace on the upper plains; Soldiers at the post spent their time with an unchanging routine of drill and fatigue duties. In 1884 Fort Sidney became regimental headquarters for the 21st Infantry. The social life of the post included countless card parties, dances, and theatrical presentations at the post theater. Citizens from the town frequently attended those events.

The monotony of garrison life was broken during the winter of 1890-91. The Ghost Dance mania brought unrest to the Sioux reservations and fear to the white settlers. Troops from Fort Sidney were sent to the Rosebud Agency until the crisis subsided.

During the 1890's it became apparent there was no longer a need to continue Fort Sidney as a military post. At this time the post consisted of some 40 buildings. The use of irrigation in the early 1870's enabled shade trees, shrubs, and a grass-covered parade ground to flourish. To the regret of the townspeople, Fort Sidney was abandoned on June 1, 1894. The buildings were sold at auction in 1899. Over the ensuing years most of the army buildings disappeared, and a residential district now obscures the site of the post. Three structures of the army period remain: the 1871 Commanding Officer's Quarters, 1872 Magazine, and the 1884 Officer's Quarters. The two officer's quarters are today maintained by the Cheyenne County Historical Society.
