Battle of Birch Coulee

The troops, commanded by Captain Hiram P. Grant, left Fort Ridgely and continued to Redwood Ferry, stopping to bury about sixteen settlers' bodies along the way. With them was Indian Agent Major Joseph Brown looking for his family that had been taken prisoner. His rank was for dealing with natives and carried no military authority with the burial detail (noted by first-hand accounts)[1] With his job experience he was able advise the detail concerning the Sioux. The following morning, Anderson and his troop crossed to the south side of the river, while Grant and his men stayed on the north. At the end of the day, Anderson's and Grant's soldiers met up again at a campsite near Birch Coulee. The two detachments had buried 54 bodies, and since neither group had seen any Indians, they figured they were safe. Meanwhile, Chief Little Crow was leading a force of 110 northeastward from New Ulm, while his chief warrior, Gray Bird, was heading down the south side of the Minnesota River with a force of 350 Indians. Gray Bird's party and Brown's troops missed encountering each other during the day, but some Indian scouts discovered that Brown's troops were moving toward the campsite at Birch Coulee. The Sioux planned to ambush Brown's troops in the morning, thinking that only the infantry was present and that they could be easily destroyed.

The Birch Coulee campsite was not easily defensible, since the Indians could approach from all sides and still remain under cover. Also, since the burial detail felt themselves safe, they did not take precautions against attack such as digging entrenchments and posting sentries far enough from camp to give ample warning. During the night, Gray Bird, along with chiefs Red Legs, Big Eagle, and Mankato crossed the Minnesota River and surrounded the camp. In the morning, the Indians commenced their ambush, wounding at least thirty men of the 5th Minnesota and killing most of the Infantry's horses within the first few minutes. The heaviest part of the fight lasted about an hour, but the siege continued for many hours past then. Colonel Sibley could hear the sounds of the battle from Fort Ridgely, about sixteen miles away, so he sent out a relief party of 240 men. Colonel McPhail, heading up the relief party, thought he was almost completely surrounded by the Sioux and sent back for more reinforcements. Sibley returned with more reinforcements and artillery. The shelling forced the Sioux to disperse, and Sibley entered Brown's camp around 11 am on September 3. He encountered a "sickening sight", with twenty-two men and ninety horses dead, forty-seven men severely wounded, and others less severely hurt. The survivors were exhausted from a thirty-one hour siege without water or food.

The battle of Birch Coulee was the most deadly for the United States forces in the Dakota War of 1862. Colonel Sibley decided against taking responsibility for the disaster. In his military reports and in press dispatches he started to refer to the encounter as the 'attack on J.R. Brown's party.' The monument at Birch Coulee Battlefield correctly states that Captain Hiram P. Grant was in command, as do most first-hand accounts of the battle. Many historians mistakenly acknowledge that Brown was in command based on inaccurate reports written by Colonel Sibley. The battle may have distracted the Sioux from continuing down the Minnesota River toward more settlements, but the Americans forces learned that it was foolish to travel in hostile Indian territory with too few untrained troops.

Captain Joseph Anderson Company of Mounted Men "The Cullen Guard" went to the relief of New Ulm and was at the Battle of Birch Coulee. Casualties:
