On the morning of September 10, 1865, Cole's, and Walker's column's were encamped near the confluence of the Little Powder River and the Powder River when Native American warriors appeared. There were volleys and some sporadic firing. On September 11, there was more light skirmishing. On September 13, two scouts from Brigadier General Connor's column found Walker's and Cole's column's on Powder River and informed them of the newly established Fort Connor on Powder River east of Kaycee, Wyoming. Cole, Walker and their soldiers arrived there on September 20, 1865. Connor deemed the soldiers unfit for further service and sent them back to Fort Laramie where most of them were mustered out of the army.
