Next summer--Gen. Pope being in command of this department — the irregular frontier line of settlements in the north-west was picketed by about 2,000 men; while Gen. Sibley moved westward from Fort Snelling in June, with some 2,500 infantry; Gen. Sully, with a body of cavalry being sent up the Missouri on boats to cooperate. The two commands did not unite; but Sibley found and fought¹ some of the hostile savages at Missouri Couteau, Big mound, Dead Buffalo lake, and Stony lake; killing or wounding some 130) of them; while Sully encountered² a band at Whitestone hill, routing then with heavy loss, and taking 156 prisoners. The remnant fled across the Missouri and evaded pursuit. This was the virtual close of the Sioux war. Our men on these expeditions suffered terribly for water — a great drouth then prevailing on the plains.

Far West, Brig.-Gen. P. E. Connor, 1st California volunteers, commanding in Utah, on hearing³ of Indian depredations by the Shoshonees on Bear river, western Idaho, marched thither (140 miles) through deep Winter snows, wherein 75 of his men were disabled by frozen feet, and, with the residue, attacked⁴ 300 savages in their stronghold, killing 224; his own loss being 12 killed and 49 wounded. Four months later, Gen. Connor, with most of his force, traversed the region westward of the Rocky mountains so far north as old Fort Hall on Snake river, but found no enemy to combat.

These Indian hostilities, though inglorious and most unprofitable, subtracted considerably from our military strength, and added largely to our exhausting outlays during the trying year 1863.
