The first battle in the history of the Inner Sphere to involve BattleMechs also involved the Terran Alliance 801st Heavy Armored Regiment. A lance of Mackies led by Lt. Colonel Amanda Cunningham from the 801st faced a company of armored vehicles from the Draconis Combine on the planet Styx, which the Kuritans were attempting to raid. The 'Mechs from the 801st easily handled the Combine tanks and their infantry support outside the city of Barbados; faced with the new Hegemony weapons on a battlefield marred by wet weather conditions and mud, only a single Combine tank and a few infantry were left alive from the raiding party at the end of the battle. This overwhelming victory proved to most that BattleMech technology would be decisive in future battles.
