Mazeppa accordingly made out a statement of his complaints, and appointed his nephew a commissioner to proceed to head-quarters and lay them before the Czar. The name of the nephew was Warnarowski. As soon as Warnarowski arrived at the camp, Peter, instead of granting him an audience, and listening to the statement which he had to make, ordered him to be seized and sent to prison, as if he were guilty of a species of treason in coming to trouble his sovereign with complaints and difficulties at such a time, when the country was suffering under an actual invasion from a foreign enemy.
As soon as Mazeppa heard that his nephew was arrested, he was convinced that his plots had been discovered, and that he must not lose a moment in carrying them into execution, or all would be lost. He accordingly immediately put his whole force in motion to march toward the place where the Swedish army was then posted, ostensibly for the purpose of attacking them. He crossed a certain river which lay between him and the Swedes, and then, when safely over, he stated to his men what he intended to do.
The men were filled with indignation at this proposal, which, being wholly unexpected, came upon them by surprise. They refused to join in the revolt. A scene of great excitement and confusion followed. A portion of the Cossacks, those with whom Mazeppa had come to an understanding beforehand, were disposed to go with him, but the rest were filled with vexation and rage. They declared that they would seize their chieftain, bind him hand and foot, and send him to the Czar. Indeed, it is highly probable that the two factions would have come soon to a bloody fight for the possession of the person of their chieftain, in which case he would very likely have been torn to pieces in the struggle, if those who were disposed to revolt had not fled before the opposition to their movement had time to become organized. Mazeppa and those who adhered to him--about two thousand men in all--went over in a body to the camp of the Swedes. The rest, led by the officers that still remained faithful, marched at once to the nearest body of Russian forces, and put themselves under the command of the Russian general there.
