The Battle of Herodotus was a major, days long, battle fought during the final months of the Nietzschean Uprising on and in orbit above the planet Herodotus.
The battle was fought over control of a vital Slipstream Nexus the Systems Commonwealth forces could use to attack Nietzschean strategic assests across the galaxy. Realizing this the Nietzschean Alliance mobilized a battle group with the intention of taking this important Nexus from the High Guard and using it to further their own war plans against the Commonwealth. In defense of the system the planet had been fortified planetside as well as in space to fend off the approaching Nietzschean fleet hoping that the conditions created by the Nexus, the merger of its various slip points which forced ships to drop out of FTL for several minutes to change slipstream junctions, would assist in the High Guard's struggle and essentially act as a natural fortification. Unfortunately the Nietzscheans' superior numbers over took the Commonwealth ships and orbital defenders as well as the ground forces under the command of Than General Sky Falls in Thunder who quickly became overwhelmed by enemy firepower.
Accepting that the battle was lost the High Guard disbatched the Pax Magellanic to rescue the contingent of Lancers under the command of General Sky Falls who had been pinned down by the Nietzscheans. In this effort the Pax deployed all of her 4,000+ crew members including Captain Warrick to assist in close combat on the ground; however, they too were overrun but not before Warrick called down friendly fire on his own position. As this was happening, Nitezscheans were on their way to board the Pax Magellanic. To prevent this Captain Warrick ordered the she ship's AI, named Jill Pearce to destroy herself. However, Pearce was in a relationship with her Captain and thought that his order to kill him and herself insteading of escaping to San-Ska-Re was a major personal and romantic betrayal. Spurned, she ejected the Pax's Exotic Matter Pulsar at the planet. The planet exploded, spreading it's debris all over the system and stranding the Pax in the system because non-relativistic travel would have taken hundreds of years.
