From Halopedia, the Halo wiki
In the Siege of the Atlas Moons UNSC forces fought the Covenant on the moons of the planet Atlas. UNSC forces won on ground, and won in space
Little 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 a rare victory for the UNSC, seeing as victories in space were uncommon and have been very rare.
