שמשון בן פסח אוסטרופולי

Samson ben Pesah Ostropoli, was a Polish rabbi and Kabbalist from Ostropol who was killed at Polonnoye, Volhynia, during the Khmelnytsky Uprising. When the Cossacks laid siege to Polonnoye, Samson, with 300 of his followers, arrayed in their shrouds and praying-shawls, went to the synagogue, and stood there praying until the enemy came and butchered them all.
