The Bactrians in the army wore a headgear very similar to the Median, carrying their native reed bows and short spears.

The Sacae, who are Scythians, had on their heads tall caps, erect and stiff and tapering to a point; they wore trousers, and carried their native bows, and daggers, and also axes which they call “sagaris.” These were Amyrgian Scythians, but were called Sacae; that is the Persian name for all Scythians. The commander of the Bactrians and Sacae was Hystaspes, son of Darius and Cyrus' daughter Atossa.
