Battle of Yggdrasil (Conflicted Hearts)

The Battle of Yggdrasil was a Battle between the Earth Alliance's OMNI Enforcers and the PLANT Homeland's ZAFT Forces, it lasted about a month and ended with Isao Kofun coordinating the destruction of Yggdrasil, causing the deaths of all the Naturals on the Space Station.

This was one of the first ZAFT victories of the War and one of the few battles where Rau, Andrew and Isao's natural skills in combat became shown to the ZAFT brass.

Aftermath
Following the Battle of Yggdrasil, the ZAFT Forces moved to prove their dominance over Space conflict and many descent operations were launched eventually leading to Andrew Waltfeld leaving both Isao and Rau to battle down on the Earth, the ZAFT Fleet meanwhile fought a number of minor skirmishes but were mostly kept close to the PLANTs or resupplying the ZAFT Forces on Earth from Orbit.
