The year is UC 796 (Imperial Calendar year 487). The Free Planets Alliance expedition, thirty million soldiers strong, entered Imperial territory and engaged with Fleet Admiral Reinhard's massive fleet as well as the entire Galactic Empire Space Fleet, also led by Reinhard as its new vice commander. As a result, the Alliance lost three of its eight fleets. However, after learning the intentions of the Free Planets Alliance High Council, Commander-in-Chief Lobos gave the order for the surviving fleets to assemble and continue the battle. Reinhard, desiring a perfect victory, advanced on the Amritsar Starzone, where the remaining Alliance fleets were amassing. And so the curtain rose on the Battle of Amritsar.
