Late that night a detachment of 14 men of Company I, 3rd U.S. Volunteer Infantry led by Capt. Adam Smith Leib, escorted by 1st Lt. Henry C. Bretney and six (some accounts say 10) troopers of Company G, 11th Ohio Volunteer Cavalry, arrived from Sweetwater Station en route to Fort Laramie for supplies and a long-overdue payroll. They found the station on 50% guard duty and molding bullets. Leib advised the station commander, Major Martin Anderson of the 11th Kansas Cavalry, that he had earlier passed a small train of five empty mule-drawn wagons returning from Sweetwater to Laramie, 14 teamsters escorted by 11 enlisted men of the 11th Kansas. Knowing that the train was due to come in the next morning, the officers at the post discussed sending out a relief force to drive off the Cheyenne and Lakota warriors, so that the wagon train could come safely in. Leib and Bretney suggested an immediate march but Anderson decided to wait for daylight. Bretney, who had succeeded to command of Company G on February 13 when its captain, Levi M. Rinehart, had been accidentally killed by a drunken trooper during a skirmish, was not on good terms with Anderson. On his arrival at Platte Bridge on July 16, the Kansan had replaced Bretney as post commander and ordered Company G to relocate to Sweetwater Station, escorting the same wagon train now returning from there. In addition, the 11th Kansas Cavalry was due to march to Fort Kearney on or about August 1 to muster out of service.
