Generals Terry and Gibbon met about fifteen miles below the mouth of the Tongue River on the 9th of June, and their combined forces formed a junction at the mouth of the Rosebud on the 21st of that month. Here the plan of operations against the Indians was agreed upon. Nothing was known of Crook’s whereabouts, nor of his recent fight, but it was pretty well established, from various scouting parties, that the Indian village was in the valley of the Little Big Horn, from seventy-five to ninety miles distant. It was decided that General Custer, with the 7th Cavalry, should proceed up the Rosebud until he should strike a large Indian trail which had been discovered a few days before, and should then follow it to the Little Big Horn, feeling well to the south to prevent the escape of the Indians. General Gibbon, whose column General Terry accompanied, was to ascend the Yellowstone to the mouth of the Big Horn, and that stream to the mouth of the Little Big Horn, where it was expected to arrive not later than the 26th, and where it should come into touch with Custer. [Sidenote: THE CUSTER MASSACRE.] In carrying out his part of the programme, General Custer moved more rapidly than his instructions contemplated, so rapidly, in fact, that he would have arrived at the appointed rendezvous, had his march not been interrupted, an entire day in advance of that fixed for the arrival of General Gibbon. The result was that his command came upon the Indian village on the morning of the 25th while advancing in three separate columns not within supporting distance of each other. Custer’s column was surrounded and annihilated to a man. The other two detachments, under Major Reno and Captain Benteen, effected a junction and intrenched themselves on the river bluff of the Little Big Horn, where they withstood for nearly thirty hours the terrific siege by the Indians, who were confident and exultant from their late victory over Custer. The total loss to Custer’s command was about 270 men. General Gibbon’s column reached the scene of the battle on the 27th, the Indians withdrawing upon their approach. [Sidenote: MILITARY PROBLEM SOLVED.] This was the crowning tragedy of the long Sioux wars, which had been waged at intervals for upward of twenty years. Although a great disaster to the whites, it marked the downfall of the Indian power. The various bands into which the hostile force scattered after the Custer massacre were relentlessly pursued until all were driven into the reservations or beyond the British line. Once on the reservations they were disarmed and dismounted, so as to cripple them from further resistance. Another year was consumed in this work, and the military posts were further extended into the Indian country; but by the end of 1877 the military problem in our Indian affairs was practically solved.
