The Battle of Killdeer Mountain took place during Brig. Gen. Alfred Sully's expedition against the Sioux in Dakota Territory July 28–29, 1864. The location of the battleground is in modern Dunn County, North Dakota. With a total of more than 4,000 soldiers involved in the total operation, and more than 2,000 in the battle, Sully's expedition was the largest ever carried out by the U.S. army against Native Americans.
The Sioux Wars were a series of conflicts between the United States and various subgroups of the Sioux people which occurred in the later half of the 19th century. The earliest conflict came in 1854 when a fight broke out at Fort Laramie in Wyoming, when Sioux warriors killed 31 American soldiers in the Grattan Massacre, and the final came in 1890 during the Ghost Dance War.
Fort Ridgely was a frontier United States Army outpost from 1851 to 1867, built 1853–1854 in Minnesota Territory. The Sioux called it Esa Tonka. It was located overlooking the Minnesota River southwest of Fairfax, Minnesota. Half of the fort's land was part of the south reservation in the Minnesota river valley for the Mdewakanton and Wahpekute tribes. Fort Ridgely had no defensive wall, palisade, or guard towers. The Army referred to the fort as the "New Post on the Upper Minnesota" until it was named for two Maryland Army Officers named Ridgely, who died during the Mexican–American War.
The Powder River Expedition of 1865 also known as the Powder River War or Powder River Invasion, was a large and far-flung military operation of the United States Army against the Lakota Sioux, Cheyenne, and Arapaho Indians in Montana Territory and Dakota Territory. Although soldiers destroyed one Arapaho village and established Fort Connor to protect gold miners on the Bozeman Trail, the expedition is considered a failure because it failed to defeat or intimidate the Indians.
The Battle of Big Mound was a United States Army victory in July 1863 over the Santee Sioux Indians allied with some Yankton, Yanktonai and Teton Sioux in Dakota Territory.
The Battle of Dead Buffalo Lake was a skirmish in July 1863 in Dakota Territory between United States army forces and Santee, Yankton, Yanktonai and Teton Sioux. The Sioux attempted to capture the pack train of the army and retired from the field when they were unsuccessful.
The Battle of Whitestone Hill was the culmination of the 1863 operations against the Sioux or Dakota people in Dakota Territory. Brigadier General Alfred Sully attacked a village September 3–5, 1863. The Native Americans in the village included Yanktonai, Santee, and Teton (Lakota) Sioux. Sully killed, wounded, or captured 300 to 400 Sioux, including women and children, at a cost of about 60 casualties. Sully continued the conflict with another campaign in 1864.
Alfred Sully, was an American military officer who served in the United States Army during the Mexican-American War and the American Indian Wars. He served as Brevet Brigadier General in the Union Army during the American Civil War but was removed from command by John Gibbon and charged with dereliction of duty for failure to suppress a mutiny by the 34th New York Infantry Regiment. He was found innocent of the charges and sent to the Dakota Territory to serve in the Sioux Wars. After the Civil War, he served as major in the United States Army and continued to fight in the Indian Wars including the Nez Perce War and out of Fort Dodge, Fort Harker and Fort Vancouver. He served as Superintendent of Indian Affairs for Montana in 1869 and as colonel of the 21st Infantry Regiment in 1873.
The 7th Minnesota Infantry Regiment was an infantry regiment in the Union Army that served in the Western Theater of the American Civil War.
The 3rd Minnesota Light Artillery Battery was a Minnesota USV artillery battery that served in the Union Army during the American Civil War and the American Indian Wars.
The 30th Wisconsin Infantry Regiment was a volunteer infantry regiment that served in the Union Army during the American Civil War.
The Battle of Wood Lake occurred on September 23, 1862, and was the final battle in the Dakota War of 1862. The two-hour battle, which actually took place at nearby Lone Tree Lake, was a decisive victory for the U.S. forces led by Colonel Henry Hastings Sibley. With heavy casualties inflicted on the Dakota forces led by Chief Little Crow, the "hostile" Dakota warriors dispersed. Little Crow and 150 followers fled for the northern plains, while other Mdewakantons quietly joined the "friendly" Dakota camp started by the Sisseton and Wahpeton bands, which would soon become known as Camp Release.
The Battle of Birch Coulee occurred on September 2–3, 1862, and resulted in the heaviest casualties suffered by U.S. forces during the Dakota War of 1862. The battle occurred after a group of Dakota warriors followed a U.S. burial expedition, including volunteer infantry, mounted guards and civilians, to an exposed plain where they were setting up camp. That night, 200 Dakota soldiers surrounded the camp and ambushed the Birch Coulee campsite in the early morning, commencing a siege that lasted for over 30 hours, until the arrival of reinforcements and artillery led by Colonel Henry Hastings Sibley.
The Surrender at Camp Release was the final act in the Dakota War of 1862. After the Battle of Wood Lake, Colonel Henry Hastings Sibley had considered pursuing the retreating Sioux, but he realized he did not have the resources for a vigorous pursuit. Furthermore, he was aware that Chief Little Crow had been losing support and was in contact with several Mdewakanton chiefs who had signaled their opposition to further conflict.
The Dakota War of 1862, also known as the Sioux Uprising, the Dakota Uprising, the Sioux Outbreak of 1862, the Dakota Conflict, or Little Crow's War, was an armed conflict between the United States and several eastern bands of Dakota collectively known as the Santee Sioux. It began on August 18, 1862, when the Dakota, who were facing starvation and displacement, attacked white settlements at the Lower Sioux Agency along the Minnesota River valley in southwest Minnesota. The war lasted for five weeks and resulted in the deaths of hundreds of settlers and the displacement of thousands more. In the aftermath, the Dakota people were exiled from their homelands, forcibly sent to reservations in the Dakotas and Nebraska, and the State of Minnesota confiscated and sold all their remaining land in the state. The war also ended with the largest mass execution in United States history with the hanging of 38 Dakota men.
The area that eventually became the U.S. state of Montana played little direct role in the American Civil War. The closest the Confederate States Army ever came to the area was New Mexico and eastern Kansas, each over a thousand miles away. There was not even an organized territory using "Montana" until the Montana Territory was created on May 26, 1864, three years after the Battle of Fort Sumter. In 1861, the area was divided between the Dakota Territory and the Washington Territory, and in 1863, it was part of the Idaho Territory.
Shakopee or Chief Shakopee may refer to one of at least three Mdewakanton Dakota leaders who lived in the area that became Minnesota from the late 18th century through 1865. The name comes from the Dakota Śakpe meaning "Six." According to tribal histories, the very first "Shakpe" was called that because he was the sixth child of a set of sextuplets.
The 1st Dakota Cavalry was a Union battalion of two companies raised in the Dakota Territory during the American Civil War. They were deployed along the frontier, primarily to protect the settlers during the Dakota War of 1862.
The Battle of the Badlands was fought in Dakota Territory, in what is now western North Dakota, between the United States army led by General Alfred Sully and the Lakota, Yanktonai, and the Dakota Indian tribes. The battle was fought August 7–9, 1864 between what are now Medora and Sentinel Butte, North Dakota. It was an extension of the conflict begun in the Dakota War of 1862. Sully successfully marched through the badlands encountering only moderate resistance from the Sioux.
The Department of the Northwest was an U.S. Army Department created on September 6, 1862, to put down the Sioux uprising in Minnesota. Major General John Pope was made commander of the Department. At the end of the Civil War the Department was redesignated the Department of Dakota.
