From Halopedia, the Halo wiki
During the Blooding Years, Tsodon 'Sakua served under Jul 'Mdama's Covenant faction. Following 'Mdama's death at the Battle of Kamchatka, his followers were left in a state of disarray and some, like Tsodon 'Sakua, launched an attack on Sanghelios, seizing control of Sunaion. As Sunaion remained the last stronghold for the Covenant, the Swords of Sanghelios soon launched an assault to end the Covenant once and for all. During the Battle of Sunaion, 'Sakua made a personal recording in which he lamented falling back to Sunaion. He was flabbergasted at how their strength could be overcome by what he perceived as weakness in the Arbiter's forces.
