When the planet came under assault by Draconis Combine forces, which were seeking to eliminate the venerable Wolf’s Dragoons, the 10th DLC came to the assistance of the Dragoons along with the Dragoon’s own Zeta Battalion. The 1st lance “White Knights” company of CORE battalion fought off an entire reinforced company of DCMS forces before a second company of DCMS reinforcements finished off the last of the White Knight mechs. DCMS forces suffered staggering losses during the battle and eventually were forced to retreat to their dropships where they waited for stragglers before leaving the world. Although the 10th and the Dragoons won the day, it came at a massive cost, with both units fractured.
After the battle the surviving mech pilots and support staff of CORE Battalion, now without a single surviving mech to field were ordered to depart the planet. A single lance of the New Zion Defense League forces had also suffered after being conscripted into the defense of Crossing after stopping over enroute to New Ivaarsen where it had been intended to reinforce the planetary garrison. The two units were jointly redeployed to New Avalon where their experience was to be put to use training new recruits of the AFFS.
