Fort Phil Kearny

Fort Phil Kearny was an outpost of the United States Army that existed in the late 1860s in present-day northeastern Wyoming along the Bozeman Trail. Construction began Friday July 13, 1866 by Companies A, C, E and H of the 2nd Battalion, 18th Infantry, under the direction of the regimental commander and Mountain District commander Colonel Henry B. Carrington. The post was named for Maj. Gen. Philip Kearny, a popular figure in the American Civil War. The fort should be distinguished from the similarly named Fort Kearny in Nebraska, which was named for Kearny's uncle Stephen W. Kearny. Today, the fort and the nearby Fetterman and Wagon Box battle sites are maintained by the State of Wyoming as the Fort Phil Kearny State Historic Site.

The fort was located along the east side of the Bighorn Mountains in present-day northern Johnson County, approximately 15 miles (24 km) north of Buffalo. Along with Fort Reno and Fort C. F. Smith, the fort was established along the Bozeman Trail in the Powder River Country at the height of the Indian Wars to protect prospective miners traveling the trail north from the Oregon Trail to present-day Montana.

Fort Phil Kearny was the largest of the three stockaded fortifications along the trail. Its eight-foot (2.5 m) high log walls enclosed an area of 17 acres (69,000 m2). The longer walls on the north-east and south-west sides each measured 1,496 feet (456 m) in length . The width of the north-west side was 600 feet (180 m) and this tapered to 240 feet (73 m) at the south-east side. The perimeter of the stockade was approximately 3,900 feet (1,200 m) and its construction took more than 4,000 logs. Further building construction in 1867 required over 606,000 board feet of lumber and 130,000 adobe bricks.

The fort was under continuous construction and was nearing completion in December 1866, when its garrison was due to be re-designated the 27th Infantry. At its peak strength the garrison numbered 400 troops and 150 civilians: 9 officers, a surgeon, and 329 enlisted men of five infantry companies of the 18th/27th Infantry, including the newly recruited Company K, 27th; one officer and 60 men of Company C, 2nd Cavalry, and 150 civilian quartermaster and contractor employees.

The fort, known to the Indians as the "hated post on the Little Piney", played an important role in Red Cloud's War. The area around the fort was the site of the Fetterman Fight in 1866 and the Wagon Box Fight in 1867. By 1868, the Union Pacific Railroad had reached far enough west that emigrants could reach the Montana gold fields through present-day Idaho, rendering the dangerous Bozeman Trail obsolete. All three forts along the trail were abandoned as part of the Treaty of Fort Laramie (1868). Shortly after, it was burned by Cheyenne Indians.

Fort Phil Kearny, including the nearby sites of the Fetterman Fight and the Wagon Box Fight, was designated a National Historic Landmark in 1960.
