[4] Strahinja Čupić, a rich man without children from Salaš Noćajski, adopted Stojan when he was a boy, and brought him up "as though he was of his own blood".

[3] Stojan Čupić first met Karađorđe, a pig trader and Austrian veteran, somewhere in the Valjevo nahija in 1804.

[3] Čupić, who participated in the battle, hurried to Mačva to intercept the fleeing Ottoman troops; near Drenovac he cut down acclaimed Mula of Sarajevo.

[3] Along with Karađorđe and other notable commanders, he participated in the bloody Battle of Loznica (1810), which left many Turks dead.

[3] He was wounded during the battle, but still managed to save Cincar-Janko's life, about to be slain by an armored Turk soldier.

[3] At the beginning of September 1813, the Serbian rebels were defeated at Ravnje, by a strong Ottoman force commanded by French officers.

[3] The rebels were forced to retreat; Čupić swam over the Zasavica and arrived at Šabac, where he together with his blood brother, vojvode Luka Lazarević, started organizing the defense of the city.

[9] Čupić was tall, with a slender waist, wide shoulders, mid-boned, and had strong muscles and long fingers.

[12] He was dubbed "the Dragon of Noćaj" (Zmaj od Noćaja; pronounced [zmâj ɔd nɔ̌tɕaja]) in the epic poetry due to his quick-thinking and heroism.
