The Batoh (Batih) massacre (Polish: Rzeź polskich jeńców pod Batohem) was a mass execution of Polish captives after the Battle of Batih on 3–4 June 1652 near Ladyzhyn (now in Ukraine). It was carried out by Ukrainian Cossacks under the command of Hetman Bohdan Khmelnytsky.
Initially the captured Polish soldiers belonged to the Cossacks' allies, the Crimean Tatars. After the battle, the Cossacks paid the Tatars for possession of the prisoners, and promptly slaughtered the Polish captives to avenge Khmelnytsky's defeat at Berestechko in June 1651. According to Jasienica, it was the Cossack colonels Ivan Zolotaryenko and Ivan Vysochin who bought them from the Tatars. According to Widacka, Cossack's commander Khmelnytsky himself contributed 50,000 thalers for that purpose. According to Hrushevsky and Pasicznyk, Duda, and Sikora, the decision to execute the prisoners was made by Khmelnytsky himself. Afterward, between 3,000 and 5,000 and 8,000 Polish soldiers were tied up and massacred in two days of methodical beheadings and disembowelments. Zolotaryenko supervised the executions yelling "Revenge for Berestechko!", a reference to an earlier Cossack defeat at the hands of the Poles in the Battle of Berestechko.
