I'm not taking my fleet anywhere near Kardoen. That Kamikaze did a number on me and, until I get the chance to resupply, I'm not moving toward the front lines again. When I'm 200/200 again, and doing 50 cap damage every turn, I will call you back.
One of you is dead - either this coming turn or the next, no matter what we do. You can only choose when and how that single fleet will die - and who it's going to be.
If the 1st leaves, with the 2nd covering them and staying behind, they can secure Draco and resupply/retreat further next turn. The Hierarchy will likely retreat the damaged Fura, bring back the 4th Hertak and probably plow through the 2nd. They might even advance two fleets (1st Fura + Flag) to Draco, but they'd be unable to attack.
If the 2nd leaves and the 1st stays, the Hertak will do pretty much the same - but they will only need to attack with one fleet to wipe them out and they will have enough forces to move and attack Draco. However, we will have a combat-worthy fleet near the front lines (which the 1st is no more - it will need 3 resupply actions to be operational again).
We will need to cede more systems to the Hierarchy in the southern front, if we're to win this without any more losses. The way I see it, we might be better off leading them in a merry chase all the way to Tamy, while the upper front wipes out the Cordi enemy fleets up there. Then we hit them from two rotating fronts. They can't hunt us down and keep a doomstack working, because they'll have to either give chase and have the systems revert to friendly the minute they leave, or leave fleets behind to secure them. So, they either give us time to re-group, or they chase us down in a disorganized way.
EDIT: Ran some calcs on the upper front. Our heaviest hitters up there are the two SF fleets and the 2nd CRF. Even if the 4th SF retreats without support (and dies - NOT RECOMENDED!!!1!) and all three of our fleets jump and attack, they do not have enough damage output to kill an enemy. However, they might knock the 1st Fura & Zy to 3/18 (which will make them do a piddly 3/5 damage).
If two of our fleets jump in (Recommended: 2nd SF, 2nd CRF) and the 4th SF joins in the attack (yes, I am suggesting the 14% fleet attacks, problem?) they can bring the 1st FuraZy to 24/38 (Damage next turn: 9/12). The 4th SF will be down to 2%/4% (!!) but will be able to retreat with its second action (I hope the FuraZy do not have another subspace barrage up their sleeves). The 1st SF can resupply and move to Aldebaran as a second action, to be able to attack and retreat next turn, if it gets pummeled. If it doesn't, it will do full damage on its turn, which is always nice.
