Invasion of Draco III

The Battle of Draco III was a battle that showed how brutal the Covenant could be. After defeating marine ground forces, they rounded up all marine and civilian prisoners that they could find and allowed grunts and jackals to tear them apart. The Spartan-IIs watched this through satellite uplink and went to save them, but when they got there, all prisoners were killed. However, in vengeance, they slew all the Covenant there.
