Chodaczków Wielki massacre
The Chodaczków Wielki massacre (Polish: Zbrodnia w Chodaczkowie Wielkim) occurred on 16 April 1944 when 862 Poles were killed by the 14th Waffen Grenadier Division of the SS (1st Galician) in the village of Chodaczków Wielki in German occupied Poland (now Velykyi Khodachkiv, Ternopil Oblast, Ukraine.) The massacre started when the perpetrators, a division composed of ethnic Ukrainian volunteers, arrived to the town of 2,800 people in order to turn the settlement into a base to supply reinforcements for the then-ongoing siege of Ternopil. Once they entered, they began setting the houses of ethnic Poles on fire.
