Siege of the Atlas Moons
From Halopedia, the Halo wiki
In the Siege of the Atlas Moons UNSC forces fought the Covenant.
Little to nothing is known of this battle except that Vice Admiral Danforth Whitcomb fought in the engagement and gained a reputation as a great military Commander. This was seen to be a rare victory for the UNSC, as victories in space-based fighting were uncommon for the UNSC Human Fleet.
