Referred to as the Ruin, the relatively short time Dominion and Eldar forces spent in the Expanse was devastating.

Dominion Arrival

The sudden arrival of the Dominion in the Adarion Expanse set off planetary defense alarms. Any official military response was overwhelmed within hours. The militia fleet held the capitol ships at bay with guerrilla tactics for days.

Eldar Counteroffensive

Then the Eldar portals opened. Many believed them to be the saviors until the planetary bombardment began. The remaining militia forces were caught in the crossfire, they lasted little more than the military forces. Both sides then landed ground forces to engage key targets and each other. This led to even more devastation throughout the system. After a few more days both sides simply withdrew. No fanfare, no surrender, they just left the battered system to deal with the cleanup and recovery efforts.
