The Orion War began with a small battle, in which a group of five Katzec Frigates and two Light Cruisers destroyed four UOF Freighters as soon as they came out of Slipspace. The squadron then proceeded to the Freighter's destination colony, Panax, where it was recently colonized and garrison was only two Corvettes and an Orbital Defense Platform. This began the Battle of Panax II, along with the Orion War. Since the force was overwhelmingly powerful, the planet was lost. The seven-vessel battlegroup proceeded to two other colonies, Panax IV and Mercado, winning the first but being finally outgunned and retreating at the latter.
