At Byalystok Kmita seized the carriages and camp-chests of Boguslav. He wearied, weakened, and inflicted hunger on Boguslav’s troops. The choice German infantry and Swedish cavalry which the prince had brought with him were like walking skeletons, from wandering, from surprises, from sleeplessness. The mad howling of the Tartars and Kmita’s volunteers was heard in front of them, at the flanks, and in the rear. Scarcely had a wearied soldier closed his eyes when he had to seize his weapons. The farther on, the worse the condition. The small nobility inhabiting those neighborhoods joined with the Tartars, partly through hatred of the Radzivills of Birji, partly through fear of Kmita; for he punished beyond measure those who resisted. His forces increased therefore; those of Boguslav melted. Besides, Boguslav himself was really ill; and though in the heart of that man care never had its nest long, and though the astrologers, whom he believed blindly, had foretold him in Prussia that his person would meet no harm in that expedition, his ambition suffered harshly more than once. He, whose name had been repeated with admiration in the Netherlands, on the Rhine, and in France, was beaten every day in those deep forests by an unseen enemy, and overcome without a battle. There was, besides, in that pursuit such uncommon stubbornness and impetuosity passing the usual measure of war, that Boguslav with his native quickness divined after a few days that some inexorable personal enemy was following him. He learned the name Babinich easily, for the whole neighborhood repeated it; but that name was strange to him. Not less glad would he be to know the person; and on the road in times of pursuit he arranged tens and hundreds of ambushes,—always in vain. Babinich was able to avoid traps, and inflicted defeats where they were least expected. At last both armies came to the neighborhood of Sokolka. Boguslav found there the reinforcement under Kyritz, who, not knowing hitherto where the prince was, went to Yanov, where the fate of Boguslav’s expedition was to be decided. Kmita closed hermetically all the roads leading from Yanov to Sokolka, Korychyn, Kuznitsa, and Suhovola. The neighboring forests, willow woods, and thickets were occupied by the Tartars. Not a letter could pass; no wagon with provisions could be brought in. Boguslav himself was in a hurry for battle before his last biscuit in Yanov should be eaten. But as a man of quick wit, trained in every intrigue, he determined to try negotiations first. He did not know yet that Sapyeha in this kind of intrigue surpassed him greatly in reasoning and quickness. From Sokolka then in Boguslav’s name came Pan Sakovich, under-chamberlain and starosta of Oshmiana, the attendant and personal friend of Prince Boguslav, with a letter and authority to conclude peace.
