Operation Broken Blade
Broken Blade's objective was to hamper the Lyran Commonwealth's ability to manufacture war materials by destroying as much of the production facilities on Hesperus II as possible. Though the Combine WarShips managed to destroy some orbiting factories they were unable to support the ground assault because of the strong Lyran defense fleet. But since the attackers plan presupposed orbital support, the ground attack failed to overcome the defenders. The DCMS withdrew in January of 2788, having suffered more casualties than they had dealt.
