The irregulars destroyed the great army piecemeal. They gathered the fallen leaves that dropped of themselves from that withered tree—the French army—and sometimes shook that tree itself. By October, when the French were fleeing toward Smolénsk, there were hundreds of such companies, of various sizes and characters. There were some that adopted all the army methods and had infantry, artillery, staffs, and the comforts of life. Others consisted solely of Cossack cavalry.

A sacristan commanded one party which captured several hundred prisoners in the course of a month; and there was Vasílisa, the wife of a village elder, who slew hundreds of the French.
The partisan warfare flamed up most fiercely in the latter days of October. Its first period had passed: when the partisans themselves, amazed at their own boldness, feared every minute to be surrounded and captured by the French, and hid in the forests without unsaddling, hardly daring to dismount and always expecting to be pursued. By the end of October this kind of warfare had taken definite shape: it had become clear to all what could be ventured against the French and what could not. Now only the commanders of detachments with staffs, and moving according to rules at a distance from the French, still regarded many things as impossible. The small bands that had started their activities long before and had already observed the French closely considered things possible which the commanders of the big detachments did not dare to contemplate. The Cossacks and peasants who crept in among the French now considered everything possible.
On October 22, Denísov (who was one of the irregulars) was with his group at the height of the guerrilla enthusiasm. Since early morning he and his party had been on the move. All day long he had been watching from the forest that skirted the high road a large French convoy of cavalry baggage and Russian prisoners separated from the rest of the army,
