Co'rak was the site of a battle between Apophis and another Goa'uld. Teal'c as first prime commanded Apophis's fleet, the first prime Arkad commanded the other. Arkad's fleet fed in an embarassing defeat. Teal'c bombarded the planet from space, leaving no survivors. Arkad's parents and sister were killed in the bombardment.
Teal'c's mother was murdered, her throat slit in the night on Chulak, shortly after the battle.
