 With Armenia and the Caucasus secured, Antony marched south, crossing into the Parthian province of Media Atropatene.Though Antony desired a pitched battle, the Parthians would not engage, allowing Antony to march deep into Parthian territory by mid-August of 36 BC.This forced Antony to leave his logistics train in the care of two legions (approximately 10,000 soldiers), which was then attacked and completely destroyed by the Parthian army before Antony could rescue them.
