Supox and Utwig offensive against the Kohr-Ah
When the Utwig and the Supox go into battle against the Kohr-Ah to balance the Doctrinal Conflict between the two Ur-Quan subspecies, they initially fight separated - the Supox at Antares and the Utwig in the Horologii stars.
At first, the Ur-Quan are taken by surprise and lose the Horologii stars and Antares, but they soon cope with the threat and deploy their forces accordingly — both the Kohr-Ah and the Kzer-Za (who did not recognize the Supox and Utwig efforts on their behalf) fight against the intruders in the battleground of the Doctrinal Conflict, causing grievous losses, especially in the ranks of the Supox, by taking advantage of their inadequate tactics. After a while, though, the Utwig and the Supox realize that they should work in tandem, the Utwig Juggers providing cover and absorbing the Kohr-Ah Marauders' attack, while the Supox Blades wait for the depletion of the enemy battery, at which point they charge.
As a consequence, each of the two races split their forces between the two fronts at Antares and at Horologii, still facing a very strong opposition. During the battle, numerous Ur-Quan broadcasts were intercepted, including one sent by a Kzer-Za Lord to a Kohr-Ah captain, containing a single word, "Sa-Matra" (after which the Marauder disengaged from combat and proceeded towards the Crateris constellation). These broadcasts (and possibly those sent by the Utwig and Supox ships) were so strong as to reach the Syreen starbase around Gaia. At some point, the Antares front is abandoned, and the combined forces of the Supox and the Utwig proceed towards the Horologii constellation to intercept the Kohr-Ah, eventually being overwhelmed by their superior numbers and forced to withdraw, with their forces severely crippled. The casualties, heavily disproportionate, consisted in only a few dozen ships for the Kohr-Ah, but much more for the Supox and Utwig. The entire offensive takes 160 days, not counting the 21 days necessary for the initial advance towards the Kohr-Ah space and the additional 21 days necessary for the retreat.
The offensive, although unsuccessful, delays the Kohr-Ah victory and their Death March by one year. The Zoq-Fot-Pik agents also witness the battle, and the information they relay permit those on their homeworld to approximate the time won by the Utwig and the Supox to between nine and twelve months.
If you ally the Utwig after the Kohr-Ah death march has already begun (February 17 or later, 2159), the Utwig and Supox will not launch the offensive. Instead, when you ask them for help, they each will give you 4 of their ships for free.
If you ally the Utwig after the Kohr-Ah have won the doctrinal conflict, but before they have launched the death march (which can happen if you are in Delta Crateris system at 17 February 2159), the Utwig and Supox will still go fight in the Antares and Horologii constellations -- even though the Kohr-Ah are long gone from those areas by the time they get there. The battle proceeds as normal, but it does not affect the Kohr-Ah in any manner.
