With Fire and Sword by Henryk Sienkiewicz — Read

Old Zakhar went back to Kiev after a few days' rest, and then came tidings that the commissioners had no great hopes of peace, or in fact almost despaired of it. They were able to obtain merely an armistice till the Russian Whitsuntide, in accordance with which a new commission was to begin, with plenary powers. But the demands and conditions put forth by Hmelnitski were so exorbitant that no one believed that the Commonwealth could agree to them. Vigorous arming was commenced therefore on both sides. Hmelnitski sent envoy after envoy to the Khan to hasten at the head of all his forces; he sent also to Stamboul, where Pan Bechinski, on behalf of the king, had resided for a considerable time. In the Commonwealth writs for the national militia were expected every moment. News came of the appointment of fresh leaders -- the cupbearer, Ostrorog, Lantskoronski, and Firlei -- and the complete removal from military affairs of Yeremi Vishnyevetski, who was able to shield the country only at the head of his own forces. Not merely the soldiers of the prince, not merely the nobles of Russia, but also the partisans of the former commanders were indignant at such a selection and such disfavor, declaring justly that if there had been political reasons for sacrificing Yeremi while there was hope of concluding a treaty, his removal in presence of war was a great, an unpardonable blunder; for he alone was able to meet Hmelnitski, and conquer that famous leader of rebellion. Finally the prince himself came to Zbaraj for the purpose of assembling as many forces as possible, to stand in readiness on the borderland of the conflict.

An armistice had been concluded, but at every moment it proved of no avail. Hmelnitski ordered, it is true, the execution of some colonels stationed here and there in camps, who in spite of the armistice had permitted themselves to attack castles, and squadrons encamped in various places; but he was unable to restrain the masses of the people, and the numerous independent bands, who either had not heard of the armistice, or who knew not even the meaning of the word. They attacked therefore continually the boundaries secured by the agreement, thus breaking every engagement made by the hetman. On the other hand, the troops of private persons and of the king in pursuing robbers frequently passed the Pripet and the Goryn in the province of Kiev, continued into the depth of the province of Bratslav, and there, attacked by the Cossacks, fought regular battles, not infrequently bloody and stubborn. Hence continual complaints from the Cossacks and Poles of the violation of the armistice, which it was indeed beyond the power of man to observe. The armistice existed therefore so far as Hmelnitski on one side, and the king and hetmans on the other, had not moved into the field; but the war was raging, in fact, before the main forces had rushed to the combat, and the first warm rays of spring shone again upon burning villages, towns, cities, and castles, giving light to slaughter and human misfortune.
