General Sully, being now convinced that the enemy's camp must be within a comparatively short distance, decided to make a forced march on the trail of the war party, and preparations were quickly begun. The main wagon train, as well as the Montana emigrant train, was securely corralled in a good camping place by the Heart River and a sufficient guard to protect them was detailed to remain behind, under Captain William Tripp, Company B, Dakota Cavalry. Sufficient rations were cooked to last the troops in the field for six days, the General intending to carry all supplies on pack mules taken from the train. Nothing but absolutely necessary food and ammunition was to be carried, all articles such as tents and company mess kits being left behind. But when the boxes containing the pack saddles were opened it was found, to every one's dismay, that the cincha straps of the saddles, by which they were to be secured to the mules' backs, were made of leather, about three inches wide, instead of canvas or webbing six or eight inches wide, as they should have been. When the men tried to tighten up these leather straps, they cut so cruelly into the flesh of the mules that the latter began kicking and bucking frantically and could not be quieted until they had rid themselves of their loads. General Sully, very much disgusted, was obliged to give up the plan of using a pack train, though it would have been much the easiest and quickest way to carry supplies in the rough country. Instead, he impressed into service about thirty-five of the lightest private wagons in the train, belonging to sutlers and to different companies among the troops, which had them for carrying their tents and private belongings. Each of these wagons was loaded with about one thousand pounds of food or small arms ammunition. Each soldier was supplied with all the cartridges he could carry on his person, and the limber chests of the batteries were filled with artillery ammunition. Thus equipped, the fighting forces were ready to start at three o'clock in the afternoon. The bugles blew "mount," the soldiers, teamsters, and emigrants who were being left behind cheered and waved their hats, and in a little while the long column had wound out of sight among the hills and ravines, headed north toward the Knife River.
