DEPARTMENT OF THE NORTHWEST.
As soon as the season was sufficiently advanced for a campaign against the Indians, General Pope sent a column, under Brigadier-General Sibley, up the Mississippi River to near our northern boundary, and thence across the country to the Missouri; and another of cavalry, under Brigadier-General Sully, from Sioux City up the latter river to cut off the retreat of the hostile Indians whom General Sibley might drive before him from Minnesota and Eastern Dakota. Unfortunately these movements were not well timed, and no junction was effected. A portion of the savages driven north took refuge within British territory, where our troops were not permitted to follow them. Some fled westward, and were overtaken by General Sibley near Missouri Coteau, where he encountered a force of Minnesota and Dakota warriors, estimated at from 2,200 to 2,500. In the engagements which followed at Big Mound and Dead Buffalo Lake, the Indians were completely routed, with a heavy loss in killed and wounded, and in the destruction of their provisions and means of transportation. Our loss was 5 killed and 4 wounded. The savages who escaped crossed to the west side of the Mississippi, and General Sibley reached that river, about 40 miles below Fort Clarke, on the 29th of July, having marched a distance of some 600 miles from Saint Paul.
On the 3rd of September, General Sully encountered and defeated, at White Stone Hill, about 130 miles above the Little Cheyenne, a body of Indians, a part of whom had previously been engaged against Sibley's column. The savages were defeated with a heavy loss in killed and wounded and 156 prisoners. Our loss was 20 killed and 38 wounded.*
With these operations the present Indian campaign was terminated. Recent hostilities in Idaho may render it necessary to send a military expedition into that Territory early in the spring.

Numbers 2. Report of Major General John M. Schofield, U. S. Army, commanding Department of the Missouri, of operations May 24 - December 10, 1863.
HEADQUARTERS DEPARTMENT OF THE MISSOURI,
Saint Louis, Mo., December 10, 1863.
COLONEL: I have the honor to submit a general summary of military operations in this department since the 24th of May, 1863, when I assumed this command.
At that time active operations against the organized force of the enemy in Arkansas had been suspended until the opening of the Mississippi should give us a new base and a new line of operations, by which it would be practicable to operate in the interior of Arkansas. There was no immediate employment for the troops of this department
