With Fire and Sword by Henryk Sienkiewicz — Read

Some days passed by. It appeared to men as if the vault of heaven had suddenly dropped on the Commonwealth. Jóltiya Vodi; Korsún; the destruction of the armies of the crown, ever victorious hitherto in struggles with the Cossacks; the capture of the hetmans; the awful conflagration in the whole Ukraine; slaughters, murders, unheard of since the beginning of the world -- all these came so suddenly that men almost refused to believe that so many misfortunes could come upon one land at a time. Many, in fact, did not believe it; some became helpless from terror, some lost their senses, some prophesied the coming of antichrist and the approach of the day of judgment. All social ties were severed; all intercourse between people and families was interrupted. Every authority ceased; distinction of persons vanished. Hell had freed from its chains all crimes, and let them out on the world to revel; therefore murder, pillage, perfidy, brutality, violence, robbery, frenzy, took the place of labor, uprightness, and conscience. It seemed as though henceforth people would live not through good, but through evil; that the hearts and intentions of men had become inverted, and that they held as sacred that which hitherto had been infamous, and that as infamous which hitherto had been sacred. The sun shone no longer upon the earth, for it was hidden by the smoke of conflagrations; in the night, instead of stars and moon, shone the light of fires. Towns, villages, churches, palaces, forests, went up in flames. People ceased to converse; they only groaned or howled like dogs. Life lost its value. Thousands perished without an echo, without remembrance. And from out all these calamities, deaths, groans, smoke, and burnings, there rose only one man. Every moment loftier and higher, every moment more terribly gigantic, he well-nigh obscured the light of day, and cast his shadow from sea to sea. That man was Bogdan Hmelnitski.

A hundred and twenty thousand men, armed and drunk with victory, stood ready at his nod. The mob had risen on all sides; the Cossacks of the towns joined him in every place. The country from the Pripet to the borders of the Wilderness was on fire. The insurrection extended in the provinces of Rus, Podolia, Volynia, Bratslav, Kiev, and Chernigoff. The power of the hetman increased each day. Never had the Commonwealth opposed to its most terrible enemy half the forces which he then commanded. The German emperor had not equal numbers in readiness. The storm surpassed every expectation. The hetman himself did not recognize at first his own power, and did not understand how he had risen so high. He shielded himself yet with justice, legality, and loyalty to the Commonwealth, for he did not know then that he might trample upon these expressions as empty phrases; but as his forces grew there rose in him that immeasurable, unconscious egotism the equal of which is not presented by history. The understanding of good and evil, of virtue and vice, of violence and justice, were confounded in the soul of Hmelnitski with the understanding of injuries done him, or with his personal profit. That man was honorable who was with him; that man was a criminal who was against him. He was ready to complain of the sun, and to count it as a personal injustice if sunshine were not given at his demand. Men, events, nay, the whole world, he measured with his own ego. But in spite of all the cunning, all the hypocrisy of the hetman, there was a kind of deformed good faith in this theory of his. All Hmelnitski's crimes flowed from this theory, but his good deeds as well; for if he knew no bounds in his cruelty and tyranny to an enemy, he knew how to be thankful for every even involuntary service which was rendered him.
