Sioux Wars - Colorado War

Colorado War

The Colorado War began in 1863 and was primarily fought between American militia while the United States Army played a minor role. Several native American tribes attacked American settlements in the Eastern Plains, including the Lakota Sioux who raided in northeast Colorado. On November 29, 1864 Colorado Volunteers under the command of Colonel John Chivington attacked a peaceful Cheyenne and Arapaho village camped on Sand Creek in southeastern Colorado. Under orders to take no prisoners the militia killed an estimated 150 men, women, and children, mutilating the dead and taking scalps and other grisly trophies of battle. The Indians at Sand Creek had been assured by the U.S. Government that they would be safe in the territory they were occupying, but anti-Indian sentiments by white settlers were running high. Later congressional investigations resulted in short-lived U.S. public outcry against the slaughter of the Native Americans.

Following the massacre the survivors joined the camps of the Northern Cheyenne on the Smokey Hill and Republican rivers. There the war pipe was smoked and passed from camp to camp among the Sioux, Cheyenne and Arapaho camped in the area and an attack on the stage station and fort, Camp Rankin at that time, at Julesburg on the South Platte River was planned and carried out in January, 1865. This successful attack, the Battle of Julesburg, led by the Sioux, who were most familiar with the territory, was carried out by about a thousand warriors and was followed up by numerous raids along the South Platte both east and west of Julesburg and a second raid on Julesburg in early February. Following the first raid on January 7, 500 troops under the command of General Robert B. Mitchell consisting of the Seventh Iowa Cavalry, the First Nebraska Veteran Volunteer Cavalry, and Companies "B" and "C," First Nebraska Militia (mounted) had been removed from the Platte and were engaged in a fruitless search for hostile Indians on the plains south of the Platte. They found the camp on the Republican River occupied by the tribes only after they had left. A great deal of loot was captured and many whites killed. The bulk of the natives then moved north into Nebraska on their way to the Black Hills and the Powder River but paused to burn the telegraph station on Lodgepole Creek then attacked the station at Mud Springs on the Jules cutoff. There were 9 soldiers stationed there, the telegraph operator and a few other civilians. The Indians began the attack by running the stock off from the station's corral along with a herd of cattle. Alerted by telegraph, the Army dispatched men from Fort Mitchell and Fort Laramie on February 4, about 150 men in all. Arriving on February 5 the first party of reinforcements of 36 men found themselves facing superior forces, estimated to number 500 warriors and with two men wounded were forced to retreat into the station. The second party of 120 troops under the command of Colonel William Collins, commandant of Fort Laramie, arrived on the 6th and found themselves facing 500 to 1000 warriors. Armed with Spencer repeating rifles the soldiers were able to hold their own and a standoff resulted. After about 4 hours of fighting the war party left and moved their village to the head of Brown's Creek on the north side of the North Platte. Collins' forces were soon reinforced by 50 more men from Fort Laramie who had towed a mountain howitzer with them. With a force of about 185 men Collins followed the trail of the Indians to their abandoned camp at Rock Creek Spring, then followed their plain trail to the south bank of the North Platte at Rush Creek where they encountered a force of approximately 2,000 warriors on the north side of the river. An inconclusive fight followed and the decision was made to abandon pursuit of the war party. In his report Colonel Collins correctly predicted that the party was en route to the Power River Country and would continue to raid along the North Platte. His estimate of Indian casualties during the two engagements was 100 to 150, many more than reported by George Bent a participant in the war party.

In the spring of 1865, raids continued along the Oregon trail in Nebraska. January 27, 1865 while a brisk northwest wind was blowing the army fired the prairie from Fort McPherson to Denver. The Sioux, the Northern Cheyenne, the Northern Arapaho together with the warriors who had come north after the Sand Creek massacre raided the Oregon Trail along the North Platte River, and in July, 1865 attacked the troops stationed at the bridge across the North Platte at the present site of Casper, Wyoming, the Battle of the Platte Bridge Station.
