Antoni (Antoś) Petrykiewicz (1905 – December 28, 1918) – was one of the youngest Polish defenders of Lwów (now Lviv), over which in late 1918 a Polish-Ukrainian conflict ensued. He was a pupil in the second class at Lwów Gymnasium (middle school). When he was only thirteen years old, he joined General Roman Abraham's unit, which defended Lwów's district of Persenkowka. The boy was buried on the Cemetery of the Defenders of Lwów (commonly known as "Cmentarz Orląt" or Cemetery of Eaglets).
