I don't believe that the gallic navy will reach Liberty space, can make some "scouting" but never a full attack, because to do that they have to first defeat Bretonia. In my simple opinion will be a big war. I imagine that Tau 31 is under Gallic ocupation exacept planet Harris that will continue resisting because they will fight on the air, fight on the ground, fighting on the sea but they will never surrender, so Bretonia will defend Leeds and Newcastle, while the Gaians make an non agression pact with bretonian will make raides on Edinburgh and Lewis. I also see the Kusari defending Kyushu from some gallic "scounting" patrols. The Mollys i think that they will help defending Newcastle and they will have a lot to do on Dublin, because the Corsairs will take an advantage and try to invade Dublin. Ohter thing that will also be very important is the action of the Outcast. Cali base on Tau 23 will be overrun, or heavly sieged, and that will make engage the Outcast engage the Gallic, and that will bring to another point, Tau 37. Since IMG will be neutral, the Gallic will need an advance base to prevent Outcast attacks on Tau 23, so the only base there is avaiable is Freeport 10. Of course Zoners will never let that happen so Gallic Navy will siege Freeport 10, that will resits the invasion by continues help from all zoners from Freeport 6 on Tau 29. Knowing this, Gallic will start to raid Tau 29 not only to stop the zoner's ships, but also prevent any attempt of Kusari major ofensive. While this happen, the Colonial will make continues raids on Gallic forces, to prevent any attack on Tau 44. All this will make the gallic invasion stop, not ending, because even with number superiority, it will be a huge batle front and will spread all gallic navy for too many systems.
I also think that Liberty will not have a big participation on this part of Sirius, can maybe send some suplies and sometime some ships to some kind of raid.
This is what i think that could happen, i can be wrong but ... who knows?
