Sanghelios global war

A global war on the Elite homeworld of Sanghelios erupted in late 2558. Fighting would involve the Swords of Sanghelios, Jul 'Mdama's Covenant, minor forces of the United Nations Space Command (UNSC), and finally the newly formed Created.

Conflict
Sometime after the death of Jul 'Mdama, the Covenant attacked the planet. As their forces attacked, other assets on the planet rose up. Sanghelios burst into a world wide conflict.

Despite, the battles on the planet previous to this point, this was the first time that fighting on Sanghelios was characterized as a global war.

Fighting at Nuusra
On October 27, 2558, the Covenant made a last ditch attempt to kill the Arbiter at Nuusra. Part way through the battle, the Fireteam Osiris would assist Swords forces in repelling the Covenant and extracting the Arbiter Thel 'Vadam.

After discussions took place between human forces and the Swords, Fireteam Osiris would move to a Forerunner installation to retrieve a Constructor.

Last stand
The Swords of Sanghelios moved in to Sunaion deploying Thel himself and Fireteam Osiris. They would split up with Osiris moving to take out anti-aircraft weapons.
