The Poles were exasperated beyond measure at the massacre of so many of their nobles and at the insult offered to Mariana, the tzarina. But Poland was at that time distracted by civil strife, and the king found it expedient to postpone the hour of vengeance. Zuski commenced his reign by adopting measures which gave him great popularity with the adjoining kingdoms, while they did not diminish the favorable regards of the people. But suddenly affairs assumed a new aspect, so strange that a writer of fiction would hardly have ventured to imagine it. An artful man, a schoolmaster in Poland, who could speak the Russian language, declared that he was Dmitri; that he had escaped from the massacre in his palace, and that it was another man, mistaken for him, whom the assassins had killed. Poland, inspired by revenge, eagerly embraced this man's cause. Mariana, who had been liberated from prison, was let into the secret, and willing to ascend again to the grandeur from which she had fallen, entered with cordial cooeperation into this new intrigue. The widowed tzarina and the Polish adventurer contrived their first meeting in the presence of a large concourse of nobles and citizens. They rushed together in a warm embrace, while tears of affected transport bedewed their cheeks. The farce was so admirably performed that many were deceived, and this new Dmitri and the tzarina occupied for several days the same tent in the Polish encampment, apparently as husband and wife.

This public testimonial of conjugal love led men, who had before doubted the pretender, to repose confidence in his claims. The King of Poland took advantage of the confusion now reigning in Russia to extend his dominions by wresting still more border territory from his great rival. In this exigence, Zuski purchased the loan of an army of five thousand men from Sweden by surrendering Livonia to the Swedes. With these succors united to his own troops, he marched to meet the pretended Dmitri. There was now universal confusion in Russia. The two hostile armies, avoiding a decisive engagement, were maneuvering and engaging in incessant petty skirmishes, which resulted only in bloodshed and misery. Thus five years of national woe lingered away. The people became weary of both the claimants for the crown, and the nobles boldly met, regardless of the rival combatants, and resolved to choose a new sovereign.
