== History ==
In 2555, after the Portal was reopened to reach the Ark, a lone retriever crossed it, and began harvesting Earth's minerals before being destroyed by a UNSC warship.Halo: Hunters of the Dark - p.123 Five more attacked the Mayhem on the Ark, after he crossed the portal, but all were destroyed by the ex-Covenant's ship, which was downed.Halo: Hunters of the Dark - p.142-152 Later, 000 Tragic Solitude launched a massive Retriever's force to attack Earth. Most were destroyed, but also caused heavy UNSC casualties. Earth's destruction only stopped after the Solitude, under attack of the Mayhem's crew, recalled them. The Monitor's destruction left all Retrievers intact but floating adrift in the space.Halo: Hunters of the Dark - p.355
