Sat-Okh (c. 1920 – July 3, 2003), also known as Stanisław Supłatowicz, was a soldier in the Polish Resistance during World War II and a celebrated children's author. He claimed to be Polish-Shawnee and to have grown up in Canada among Native Americans and was an important figure in the Polish "indianist" movement.
Stanisław Supłatowicz claimed to be a son of a Polish mother and Shawnee father, born in Canada and reared among his father's people. In late 1930's Sat-Okh and his mother moved to Poland. Because Supłatowicz, as a Native American, did not have a Canadian citizenship, he had to create a birth certificate to gain the Polish one. In order to do it his mother changed some of his data to hide his Native American origin.
Stanisław Supłatowicz joined the Polish resistance movement during the German occupation. He was arrested by Gestapo in 1940 and deported to Auschwitz-Birkenau, but he escaped from the train transport to the camp. Then Sat-Okh joined the Home Army, where he gained a nickname Kozak because of his bravery and fighting style based on making traps. During WWII Supłatowicz earned several medals, including the Cross of Valour. After the war he was arrested and imprisoned by communist regime for his affiliation to the Home Army. After his release Sat-Okh enlisted in the Polish Navy, where he served for six years.
Under the name Sat Okh, Stanisław Supłatowicz published several autobiographical novels for children in Polish, which were translated into several European languages. The books describe a boy's childhood and coming of age among the Native American tribe in the Northwest Territories in the 1930s, but contain many descriptions of Native American life and customs more appropriate to an earlier time and other geographical locations.
Sat Okh died in Gdańsk on July 3, 2003.
