From Halopedia, the Halo wiki
The Proclamation's Tithe was a CPV-class heavy destroyer in the Covenant Fleet of Glorious Interdiction that took part in the Battle of the Etran Harborage during the Human-Covenant War in February 2531.
The Proclamation's Tithe was sent to intercept the UNSC Spirit of Fire after its arrival inside the Etran Harborage. Despite attempted evasive maneuvers, the two ships collided, causing significant damage to the Spirit of Fire, including destroying a portion of its supply of D20 Herons, while minimal damage was done to the destroyer, due in part to its shields. The two ships soon opened fire on each other, the destroyer quickly destroying many of the Spirit of Fire's deck guns. It soon sent out Banshees and Spirits to continue the assault and destroy the Spirit of Fire's damaged power core. However, the Spirit of Fire, despite the heavy assault, managed to repair its power core and escape.
The valor and sacrifice of the destroyer's crew would later be rewarded by the Prophet of Regret who, upon his return to High Charity, had the names of every crew member both living and dead restored to the rolls of honor within the Covenant archives.
