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.
