When in the eastern part of the United States the Civil War flamed up, another war broke out in the western part. The Indians of the Plains saw their chance. While the white men, who had been busy forcing peace upon the red men, were foolishly killing each other, the red men saw themselves free to strike, and clean the buffalo country.

So the Sioux, the Cheyennes, the Kiowas and many of the Arapahos arose, to close the wagon trails, plunder the stage stations, drive out the settlers, and save the buffalo.

The result was the great Indian war of 1864. The Government hastily sent what troops it could—mainly Volunteer cavalry and infantry, assigned to fight the Western Indians instead of the Southern soldiers. Thus two wars were being waged at once.

The white Americans had extended their towns and ranches clear across the continent. Through Kansas and Nebraska there were ranches scattered clear to the Colorado mountains. Denver was growing into a city. Beyond the mountains the Mormons had built another city at the Great Salt Lake. The Overland Stage was making daily trips over the trail between the Missouri River and California. Another well-traveled stage and emigrant trail ran from the Missouri River through central Kansas, south of the Overland Trail, to Denver. And the freight wagons for New Mexico plied between Leavenworth and Kansas City, and Santa Fe, over the old Santa Fe Trail.

There were yet no railroads across the plains. But the Union Pacific of the Government's Pacific Railway was surveyed out of Omaha, for Salt Lake City and beyond; and its Kansas Division, known as the Kansas Pacific, was starting up the Kansas River, for Denver. To protect the wagon route through Kansas, and the advance of the railroad (which was following the stage road), the Government located a line of military posts; the same as upon the Overland Trail farther north, in Nebraska and westward.

The first was Fort Riley, just outside of Junction City, where the Republican River joined the Kansas River. Beyond, there was Salina; and Ellsworth on the Smoky Hill River; and southward, to guard the Santa Fe Trail over which huge quantities of Government supplies for the Southwest were being hauled, there were Camp Zarah at Walnut Creek of the Arkansas River, Fort Larned up the Arkansas, and so forth.

Many of the posts were only camps or cantonments, and received their fort name later.

In November, 1864, Captain Henry Booth started from Fort Riley to inspect the posts south to the Arkansas River in Colorado. Lieutenant Hallowell was his companion. They had planned to travel comfortably in Lieutenant Hallowell's light spring wagon instead of in a heavy jouncing army ambulance—a hack arrangement with seats along the sides and a stiff oiled-cloth top.

Lieutenant Hallowell had a canvas or wagon-sheet cover fitted over his wagon: stretched tightly upon bows and puckered to enclose the rear end with the exception of a hole in the middle there about the size of one's head. Now the spring wagon looked like a small prairie-schooner or emigrant outfit.

Captain Booth obtained from the quarter-master department the best span of Missouri mules at the fort. He and the lieutenant would do their own driving, and be independent. Whereupon, provisioned for the trip, they gaily set out, in the frosty morning, escorted by a mounted detachment of Kansas United States Volunteers under Lieutenant Van Antwerp.
