Fort Sully (South Dakota)

Fort Sully was one of the main military posts located on the east bank of the Missouri River in central Dakota built for use in the Indian Wars. There were two forts named Sully—old Fort Sully, which was in existence and occupied from 1863 to 1866, and the later, or new Fort Sully, which was established in 1866 and was continuously occupied as a military fort until its abandonment in the fall of 1894.

Old Fort Sully
Old Fort Sully 44.34611°N, -100.27472°W, in present-day Hughes County, was built by the orders of Major General Alfred Sully in September 1863 and was named for him. It was located about eighty rods from the left (east) bank of the Missouri River, a short distance above the head of Farm Island and about four and one-half miles southeast of what is now the city of Pierre, South Dakota. It was 270 ft square and was built of cottonwood timber taken from Farm Island.

A portion of the command of General Sully in the campaigns of 1863-4 and 1865 against the Sioux was garrisoned at old Fort Sully. It was abandoned in the fall of 1866 on account of Its unhealthful location on the lowlands of the Missouri. Today the site is located within the Farm Island State Recreation Area.

History
On the 13th day of October it was pronounced ready for a company, and its garrison marched in; headquarters and three companies of the Thirtieth Wisconsin; three companies of the Sixth and three of the Seventh Iowa Cavalry, all under the command of Lieutenant Colonel E. M. Bartlett of the Thirtieth Wisconsin, who, in his order assuming the command, announces that the post is to be known as Fort Sully, "in compliment to our brave commander, Brigadier General Alfred Sully, U. S. Volunteers, now commanding the District of Iowa and Dakota."

Company K., 6th Iowa cavalry, under Captain John Logan spent the ensuing winter at Fort Sully, Dakota territory, and accompanied the command under Gen. Sully, to the Devil's Lake region, in July and August.

Treaty of Fort Sully
Treaty between, the United States of America and the Yanktonai Band of Dakota or Sioux Indians. Concluded at Fort Sully, October 20, 1865.

Art. I. The Yanktonai band of Dakota or Sioux Indians, represented in council, hereby acknowledge themselves to be subject to the exclusive jurisdiction and authority of The United States, and hereby obligate and bind themselves, individually and collectively, not only to cease all hostilities against the persons and property of its citizens, but to use their influence, and, if requisite, physical force, to prevent other bands of Dakota Indians, or other adjacent tribes, from making hostile demonstrations against the Government or people of The United States.

In 1866 old Fort Sully was temporarily under the command of the Department of the Platte before being assigned to the Department of Dakota in the new Division of Missouri.

Fort Sully II
The later, or new Fort Sully, Established July 25, 1866. Its-erection was begun in July, 1866, but it was not completed until 1868. The site of the new fort, in present-day Sully County, was much more suitable and healthful than the old Fort Sully, Indeed, it was an ideal spot for a fort for defense. It stood on an elevated plateau about 160 ft above a wide and beautiful valley of the Missouri. Its site was also about the same elevation above much of the surrounding prairie. This Fort Sully was for many years one of the main military forts in Dakota.

Location
Fort Sully was situated on the east bank of the Missouri River, 20 mi below the mouth of Cheyenne River; at an elevation above the sea of about 2000 ft. The nearest town is Yancton, 300 mi below by river. The nearest posts are Fort Randall, 200 mi below, and Fort Rice, about the same distance above. The post was about halfway between the head of navigation (Fort Benton) and the mouth of the Missouri, and is 1480 mi above St. Louis. It is built on the "third terrace," a level plateau, 160 ft above low-water mark, and about the same distance below the summit level proper. On the south the surface slopes rapidly into a deep ravine, dry, except in early spring. On the west the descent is abrupt to the second terrace, a strip one hundred yards wide, on which are the stables, granary, saw-mill, smithy, interpreter's house, tavern, etc. Still further below was the river bottom, of varying width, frequently subject to overflow, moderately well timbered and very fertile. Here the company and hospital gardens are situated.

On the left bank of the Missouri river. Postoffice and telegraph station at post. Nearest town, Springfield, Dakota, 220 mi distant by wagon road, Yankton, Dakota, (terminus of the Dakota Southern R. R.), distant 262 mi by land, and 351 by Missouri river; Sioux City, Iowa, 343 mi distant by land. 575 mi by Missouri river.

Description
The post was intended for four companies. The men's quarters consist of two buildings, each 350 ft long by 17 ft wide, placed end to end, with an interval of 15 ft, which forms the sallyport. They are built of cottonwood logs, covered with pine siding, are lathed and plastered, the ceilings being 12 ft high. Transverse partitions divide the buildings into dormitories, mess-rooms, kitchens, &c. The squad-rooms measure 20 by 17 ft, are intended for 16 men each, allowing about 255 cuft air space per man. The experiment was tried for one company of removing the partitions and throwing the small rooms into one, but it was thought that this weakened the building too much. There were no wash or bath-rooms. Ablution must be performed out of doors. It was in contemplation to build a piazza for each building. The dormitories were fitted with rough wooden double bunks in two tiers. The privies, ordinary earth latrines, are 75 yards distant. The ventilation of the barracks were very defective. There were three sets of laundresses' quarters, in a large one-story house similar to the officers' quarters.

For officers' quarters there are nine detached frame buildings, built of pine, on brick foundations, with collars underneath. Each set has a back building of one story, as a kitchen. All the rooms are lathed and plastered. Three of the houses are one and a half stories high, and contain each four rooms, a hall, store-room, and pantry. Two cottages are of one story, while two others, of one and a half stories, are divided each into two sets of quarters of four rooms. None of these quarters have bath-rooms. The guard and prison-rooms are in the ends of the barrack building next the sally-port. The prisoners' room is 15 by 15 ft. The quartermaster's store-houses, two in number, measure 230 by 22 ft and 120 by 24 ft. The commissary's store-houses, also two in number, measure 228 by 17 ft and 50 by 22 ft.

The hospital was located near the brink of the ravine, to the south of the post.
