What the astounded traveller beheld was the death-struggle of the desert Turkomans, the hand of retribution smiting those savage brigands who for centuries had carried death and misery wherever they rode. These were the Tekke Turkomans, the tribes who haunted the Persian frontier, and whose annual raids swept hundreds of captives from that peaceful land to spend the remainder of their days in the most woful form of slavery. For a month previous General Skobeleff, the most daring and merciless of the Russian leaders, had besieged them in their great fort of Geop Tepe, an earthwork nearly three miles in circuit, and containing within its ample walls a desert nation, more than forty thousand in all, men, women, and children. On that day, fatal to the Turkoman power, Skobeleff had taken the fort by storm, dealing death wherever he moved, until not a man was left alive within its walls except some hundreds of fettered Persian slaves. Through its gateways a trembling multitude had fled, and upon these miserable fugitives the Russian had let loose his soldiers, horse, foot, and artillery, with the savage order to hunt them to the death and give no quarter. Only too well was the brutal order obeyed. Not men alone, but women and children as well, fell victims to the sword, and only when night put an end to the pursuit did that terrible massacre cease. By that time eight thousand persons, of both sexes and all ages, lay stretched in death upon the plain. Within the fort thousands more had fallen, the women and children here being spared. Skobeleff's report said that twenty thousand in all had been slain. Such was the frightful scene which lay before O'Donovan's eyes when he reached the mountain top, on his way to the Russian camp, a spectacle of horrible carnage which only a man of the most savage instincts could have ordered. "Bloody Eyes" the Turkomans named Skobeleff, and the title fairly indicated his ruthless lust for blood. It was his theory of war to strike hard when he struck at all, and to make each battle a lesson that would not soon be forgotten. The Turkoman nomads have been taught their lesson well. They have given no trouble since that day of slaughter and revenge. Such was one of the weapons with which the Russians conquered the desert,--the sword. It was succeeded by another,--the iron rail. It is now some twenty years since the idea of a railroad from the Caspian Sea eastward was first advanced. In 1880 a narrow-gauge road was begun to aid Skobeleff, but that daring and impetuous chief had made his march and finished his work before the rails had crept far on their way. Soon it was determined to change the narrow-gauge for a broad-gauge road, and General Annenkoff, a skilful engineer, was placed in charge in 1885, with orders to push it forward with all speed.
