The swiftly speeding weeks of that war-summer on the plains had brought many changes to the hard-worked troops engaged in the campaign or garrisoning the widely scattered posts south of the Platte. Scouting details, although constantly in the saddle, failed to prevent continued Indian depredations on exposed settlements. Stage routes were deserted, and the toiling wagons of the freighters vanished from the trails. Reports of outrages were continuous, and it became more and more evident that the various tribes were at length united in a desperate effort to halt the white advance. War parties broke through the wide-strung lines of guard, and got safely away again, leaving behind death and destruction. Only occasionally did these Indian raiders and the pursuing troops come into actual contact. The former came and went in swift forays, now appearing on the Pawnee, again on the Saline, followed by a wild ride down the valley of the Arkansas. Scattered in small bands, well mounted and armed, no one could guess where the next attack might occur. Every day brought its fresh report of horror. From north and south, east and west, news of outrages came into Sheridan's headquarters at Fort Wallace.
Denver, at the base of the mountains, was practically in state of siege, provisioned only by wagon trains sent through under strong guard; the fringe of settlement along the water ways was deserted, men and women fleeing to the nearest government posts for protection and food. The troops, few in number and widely scattered in small detachments, many being utilized as scouts and guards, were unequal to the gigantic task of protecting so wide a frontier. Skirmishes were frequent, but the Indians were wary and resourceful, and only once during the entire summer were they brought into real decisive battle. The last of August, Major Forsythe, temporarily commanding a company of volunteer scouts, was suddenly attacked by over a thousand warriors under command of Roman Nose. A four days' fight resulted, with heavy loss on both sides, the Indians being finally driven from the field by the opportune arrival of fresh troops.
The general condition of affairs is well shown by the reports reaching Fort Wallace in September. Governor Hunt wrote from Denver: "Just returned. Fearful condition of things here. Nine persons murdered by Indians yesterday, within radius of nine miles." A few days later, acting Governor Hall reported: "The Indians have again attacked our settlements in strong force, obtaining possession of the country to within twelve miles of Denver. They are more bold, fierce, and desperate in their assaults than ever before. It is impossible to drive them out and protect the families at the same time, for they are better armed, mounted, disciplined, and better officered than our men. Each hour brings intelligence of fresh barbarities, and more extensive robberies." This same month Governor Crawford, of Kansas, telegraphed, "Have just received a despatch from Hays, stating that Indians attacked, captured, and burned a train at Pawnee Fork; killed, scalped, and burned sixteen men; also attacked another train at Cimarron Crossing, which was defended until ammunition was exhausted, when the men abandoned the train, saving what stock they could. Similar attacks are of almost daily occurrence."
