The Battle of the Persian Gate was a military conflict between a Persian force, commanded by the satrap of Persis, Ariobarzanes, and the invading Hellenic League, commanded by Alexander the Great. In the winter of 330 BCE, Ariobarzanes led a last stand of the outnumbered Persian forces at the Persian Gates near Persepolis, holding back the Macedonian army for a month. Alexander eventually found a path to the rear of the Persians from the captured prisoners of war or a local shepherd, defeating the Persians and capturing Persepolis.
