This treaty also was concluded and ratified only to be broken. Chmielnicki had accepted it to strengthen himself and restore his reputation with the Cossacks. As soon as he had gained his first object, he began hostilities against the Poles, from which Jews always suffered most severely. In two years after the first insurrection of the Zaporogians, more than 300 communities were completely destroyed by death or flight, and the end of their suffering had not yet arrived. The Polish troops could not withstand the violent attacks or skillful policy of Chmielnicki. When he could no longer hope for help from the Tartars, he combined with the Russians, and incited them to a war against unhappy Poland, divided against itself. In consequence of the Russian war in the early part of 1654 and 1655, those communities suffered which had been spared by the Cossack swarms, _i. e._, the western districts and Lithuania. The community of Wilna, one of the largest, was completely depopulated (July, 1655) by slaughter on the part of the Russians and by migration. As if fate were then determining upon the partition of Poland, a new enemy was added to the Cossacks and Russians in Charles X of Sweden, who used Poland as the first available pretext to slake his thirst for war. Through the Swedish war, the communities of Great and Little Poland, from Posen to Cracow, were reduced to want and despair. The Jews of Poland had to drink the cup of poison to the dregs. The Polish general, Czarnicki, who hated the Jews, ill-used those spared by Cossacks, Russians, and the wild Swedes of the Thirty Years' War, under the pretense that they had a traitorous understanding with the Swedes. The Poles also behaved barbarously to the Jews, destroyed the synagogues, and tore up the holy scriptures. All Poland was like a bloody field of battle, on which Cossacks, Russians, Prussians, Swedes, and the troops of Prince Ragoczi of Transylvania wrestled; the Jews were ill-used or slain by all. Only the Great Elector of Brandenburg behaved leniently towards them. The number of Jewish families said to have perished in ten years of this war (600,000) is certainly exaggerated, but the slaughtered Jews of Poland may well be rated at a quarter of a million. With the decline of Poland as a power of the first rank, the importance of Polish Judaism diminished. The remnant were impoverished, depressed, and could not recover their former position. Their need was so great, that those who drifted to the neighborhood of Prussia hired themselves to Christians as day laborers for field work.
