According to a local legend, in the region near Ocieka there occurred a battle against the Tatars. The Polish knights achieved a resounding victory. To commemorate this, a hill close by became known as "‘Góra Tatarska’" (Tatar Hill). In 1531 the Grand Crown Hetman, Jan Amor Tarnowski led a Polish army against the Moldavian Prince ("‘Hospodar’") Petru IV Rareş () in the Battle of Obertyn. Despite being outnumbered four to one, the battle ended with a Polish victory, a complete Tatar surrender, and the reconquest of Pokuttya or "‘Pokuttia’" . Tarnowski brought his Tatar prisoners-of-war back to Ocieka. These prisoners became the first occupants of a new settlement near Ocieka called ‘Sadykierz’. The name ‘Sadykierz’ has distinct Tatar origins, just as do today's inhabitants of the same village ("The original settlement of ‘Sadykierz’ was located by a post-glacial lake, home to a rare species of white water-lily.")
