Besides his soldiers, Ogareff was bringing a convoy of Russian and Siberian prisoners, captured either at Omsk or Kolyvan. These unhappy creatures were not led to the enclosure--already too crowded--but were forced to remain at the outposts without shelter, almost without nourishment. What fate was Feofar-Khan reserving for these unfortunates? Would he imprison them in Tomsk, or would some bloody execution, familiar to the Tartar chiefs, remove them when they were found too inconvenient? This was the secret of the capricious Emir. This army had not come from Omsk and Kolyvan without bringing in its train the usual crowd of beggars, freebooters, pedlars, and gypsies, which compose the rear-guard of an army on the march. All these people lived on the country traversed, and left little of anything behind them. There was, therefore, a necessity for pushing forward, if only to secure provisions for the troops. The whole region between Ichim and the Obi, now completely devastated, no longer offered any resources. The Tartars left a desert behind them. Conspicuous among the gypsies who had hastened from the western provinces was the Tsigane troop, which had accompanied Michael Strogoff as far as Perm. Sangarre was there. This fierce spy, the tool of Ivan Ogareff, had not deserted her master. Ogareff had traveled rapidly to Ichim, whilst Sangarre and her band had proceeded to Omsk by the southern part of the province. It may be easily understood how useful this woman was to Ogareff. With her gypsy-band she could penetrate anywhere. Ivan Ogareff was kept acquainted with all that was going on in the very heart of the invaded provinces. There were a hundred eyes, a hundred ears, open in his service. Besides, he paid liberally for this espionage, from which he derived so much advantage. Once Sangarre, being implicated in a very serious affair, had been saved by the Russian officer. She never forgot what she owed him, and had devoted herself to his service body and soul. When Ivan Ogareff entered on the path of treason, he saw at once how he might turn this woman to account. Whatever order he might give her, Sangarre would execute it. An inexplicable instinct, more powerful still than that of gratitude, had urged her to make herself the slave of the traitor to whom she had been attached since the very beginning of his exile in Siberia. Confidante and accomplice, Sangarre, without country, without family, had been delighted to put her vagabond life to the service of the invaders thrown by Ogareff on Siberia. To the wonderful cunning natural to her race she added a wild energy, which knew neither forgiveness nor pity. She was a savage worthy to share the wigwam of an Apache or the hut of an Andaman.
