At this time General Sully was at Fort Pierre. The transportation of his supplies had delayed him, and it was not until the 14th of August that he started from that point on his march north. He went up the east bank of the Missouri, with a great deal of vexatious delay, and finally reached the scene of Sibley’s third fight just a month after it had taken place. The Indians, meanwhile, far from being conquered or dispirited, had recrossed the river and were on their way back to the grazing grounds on the Coteau of the Missouri. Some of them harassed the homeward-bound column of General Sibley. Sully pursued them to the northeast and overtook and fought them at Whitestone Hill, some thirty miles south and slightly west of Jamestown, N. D. The Indians were badly defeated, many of them were killed, and a large amount of their property was destroyed. Sully then returned to the Missouri and built a new post, Fort Sully, on the left bank of the river, opposite the head of Farm Island, midway between Fort Pierre and Fort George. With this work the campaign of 1863 came to an end. [Sidenote: CAMPAIGN INDECISIVE.] The movements of troops in this campaign and the force of Indians engaged were the largest yet known in the history of the United States. The number of warriors was estimated at over six thousand, while the troops under Sibley and Sully numbered about four thousand. The campaign, however, was not conclusive. Although the Indians had been defeated with severe loss in every engagement, they were still unsubdued, and retained their defiant attitude during the following winter. Accordingly another campaign was planned for the summer of 1864. General Sully was placed in charge with a cavalry force of about 2500 men. [Sidenote: SULLY’S CAMPAIGN OF 1864.] General Sully’s first move was to build a post near the mouth of the Cannon Ball River--Fort Rice, forty miles below where Bismarck now stands, and on the other side of the river. The Indians being reported as near the source of Heart River, General Sully concluded to continue his march in search of them, whether found or not, until he should reach the Yellowstone River. He took with him only the necessary rations for the march and sent his steamboats with supplies and materials for a new post around to meet him at the Brasseau Houses on the Yellowstone, fifty miles above the mouth of that stream. Accompanying Sully’s march to the Yellowstone was an emigrant train of about 125 people bound for the mines of Montana.
