Simple, once you destroy the inhibitor, just warp away from that Audemedon fleet as fast as possible. Go to the Ishima fleet and wait with them. Once the Audemedons attack, they won't be able to only attack you because there's all these Ishima ships attacking them! Go for the enemy carriers first, then attack the enemy cruisers, the gunships are slow enough to be attacked by the Ishimans so don't worry to much about them. If your Eleejetian cruiser gets destroyed, transfer control to an Ishiman HVD. With your fullerene pulse you can easily tear through enemy ships.
This level requires lots of skill, especially when engaging the first Audemedon fleet. You must be a good pilot in order to beat this level. Don't worry if you try to beat it a few times and you fail, that's what happened to me when I tried it, but you'll eventually beat it.
One tip is to stay away from the Audemedons Inasa pulse guns, they are DEADLY! If you get in a head to head fire fight with an Audemedon gunship, you'll probably loose. And remember that the Eleejetian cruiser is not very well armored, be careful.
I'll eventually be posting an Ares level guide. That will certainly help players like you beat hard levels.
Hope my advice helped!
