The start of the battle for Inus. Battle groups Tethys and Goliath versus a large thargoid invasion fleet.
After I got that Invader, my next target was a Thargoid Cruiser, which took absolutely ages to die. By that point the battle was almost over - both Behemoths gone, and most of the frigates and fighters, but the Thargoids were down to one Battleship, a few Cruisers, and a couple of Invaders. The Battleship made an attempt to go in-system, but we tracked it down in time.
Final survivors:
Galactic Navy: One Navy Minesweeper, one very battered reserve Cobra III, and one abandoned Navy Transport that can probably be patched up.
Thargoids: About a hundred thargons, which will make a nice present for the next few traders coming that way.
