Battle of Satala

The Battle of Satala was fought between the forces of the Eastern Roman (Byzantine) Empire and the Sassanid (Persian) Empire in summer 530, near Satala in Byzantine Armenia. The Persian army approached the city to lay siege, when it was attacked in the rear by a small Byzantine force. The Persians turned back to meet them, but were then attacked by the main army from inside the city. A determined attack by a Byzantine unit led to the loss of the Persian general's flag, causing the panicking Persians to retreat.
