1648 June 24, TULCZYN (Poland)
An agreement between the 2,000 Jews and 600 Christians of Tulczyn to defend it at all costs succeeded in preventing the Cossacks from capturing the town. Kryvonos, the Cossack leader, contacted the local governor and offered to leave the Poles alone if he gave them the Jews. The Jews found out about the plan and only through the intervention of leader Rabbi Aaron (who feared reprisals) persuaded them not to kill the local leaders. Instead, Rabbi Aaron convinced the governor to take a high ransom and give it to the Cossacks. Kryvonos accepted the ransom, entered the town, killed most of the Jews and then killed the Poles for betraying the Jews. For the most part, during the entire war, the Poles and the Jews were uneasy allies against the Cossacks.
