Weinryb cites the calculations of indicating that about 50,000 Jews lived in the area where the uprising occurred. See B. Weinryb, "The Hebrew Chronicles on Bohdan Khmelnytsky and the Cossack-Polish War", "Harvard Ukrainian Studies" 1 (1977): 153–77. While many of them were killed, Jewish losses did not reach the hair-raising figures that are often associated with the uprising. In the words of Weinryb ("The Jews of Poland", 193–4), "The fragmentary information of the period—and to a great extent information from subsequent years, including reports of recovery—clearly indicate that the catastrophe may have not been as great as has been assumed."
