The tourist, looking from his car-window as he is whirled with the speed of a tornado toward the snow-capped peaks of the "Great Divide," may see as he approaches Walnut Creek, three miles east of the town of Great Bend in Kansas, on the beautiful ranch of Hon. D. Heizer, not far from the stream, and close to the house, a series of graves, numbering, perhaps, a score. These have been most religiously cared for by the patriotic proprietor of the place during all the long years since 1864, as he believes them to be the last resting-place of soldiers who were once a portion of the garrison of Fort Zarah, the ruins of which (now a mere hole in the earth) are but a few hundred yards away, on the opposite side of the railroad track, plainly visible from the train.

The Walnut debouches into the Arkansas a short distance from where the railroad crosses the creek, and at this point, too, the trail from Fort Leavenworth merges into the Old Santa Fe. The broad pathway is very easily recognized here; for it runs over a hard, flinty, low divide, that has never been disturbed by the plough, and the traveller has only to cast his eyes in a northeasterly direction in order to see it plainly.

The creek is fairly well timbered to-day, as it has been ever since the first caravan crossed the clear water of the little stream. It was always a favourite place of ambush by the Indians, and many a conflict has occurred in the beautiful bottom bounded by a margin of trees on two sides, between the traders, trappers, troops, and the Indians, and also between the several tribes that were hereditary enemies, particularly the Pawnees and the Cheyennes. It is only about sixteen miles east of Pawnee Rock, and included in that region of debatable ground where no band of Indians dared establish a permanent village; for it was claimed by all the tribes, but really owned by none.

In 1864 the commerce of the great plains had reached enormous proportions, and immense caravans rolled day after day toward the blue hills which guard the portals of New Mexico, and the precious freight constantly tempted the wily savages to plunder.

To protect the caravans on their monotonous route through the "Desert," as this portion of the plains was then termed, troops were stationed, a mere handful relatively, at intervals on the Trail, to escort the freighters and mail coaches over the most exposed and dangerous portions of the way.

On the bank of the Walnut, at this time, were stationed three hundred unassigned recruits of the Third Wisconsin Cavalry, under the command of Captain Conkey. This point was rightly regarded as one of the most important on the whole overland route; for near it passed the favourite highway of the Indians on their yearly migrations north and south, in the wake of the strange elliptical march of the buffalo far beyond the Platte, and back to the sunny knolls of the Canadian.

This primitive cantonment which grew rapidly in strategical importance, was two years later made quite formidable defensively, and named Fort Zarah, in memory of the youngest son of Major General Curtis, who was killed by guerillas somewhere south of Fort Scott, Kansas, while escorting General James G. Blunt, of frontier fame during the Civil War.

Captain Henry Booth, during the year above mentioned, was chief of cavalry and inspecting officer of the military district of the Upper Arkansas, the western geographical limits of which extended to the foot-hills of the mountains.

One day he received an order from the head-quarters of the department to make a special inspection of all the outposts on the Santa Fe Trail. He was stationed at Fort Riley at the time, and the evening the order arrived, active preparations were immediately commenced for his extended and hazardous trip across the plains. Lieutenant Hallowell, of the Ninth Wisconsin Battery, was to accompany him, and both officers went at once to their quarters, took down from the walls, where they had been hanging idly for weeks, their rifles and pistols, and carefully examined and brushed them up for possible service in the dreary Arkansas bottom. Camp-kettles, until late in the night, sizzled and sputtered over crackling log-fires; for their proposed ride beyond the settlements demanded cooked rations for many a weary day. All the preliminaries arranged, the question of the means of transportation was determined, and, curiously enough, it saved the lives of the two officers in the terrible gauntlet they were destined to run.

Hallowell was a famous whip, and prided himself upon the exceptionally fine turnout which he daily drove among the picturesque hills around the fort.
