White Couriers (Polish: Biali Kurierzy) was a group of around 20-30 Polish boyscouts and former soldiers of the Polish Army, most of whom had been associated with the interbellum sports club Junak Drohobycz. It existed between October 1939 and July 1940, when it was broken by the Soviet NKVD. The task of the White Couriers was to smuggle people from Soviet-occupied southeastern part of the Second Polish Republic, to the Hungarian province of Carpathian Ruthenia and further to Budapest. The White Couriers were part of the Grey Ranks (Polish: Szare Szeregi), a wartime codename for the underground Polish Scouting Association
