An invasion without a reliable ally
Crassus advances deep into Mesopotamia with incomplete local intelligence and without the Armenian support he expected.
Battle
Carrhes
53 BC
A heavy army becomes a target when faced with a mobile, well-supplied force.
Military history
How did a disciplined Roman army lose its ability to fight against an enemy that controlled the distance?
Carrhae was not a simple contest between Roman courage and eastern cavalry. Crassus brought a force designed for close combat onto a plain where the Parthians could shoot, maneuver, and return without running short of missiles.
An exposed plain
The terrain offers the legions no protection from missile fire. Their greatest strength—close combat—becomes difficult to achieve.
Two systems of warfare
The Parthians do not seek to hold a fixed line. They use distance, mobility, and a shock reserve.
