Ouch. As bad as things look to the south right now, I think we need to press the attack and kill the 1st Hertak. If we don't blunt their offensive, they'll keep munching on our fleets. The 4th CRF's still in the fight; one round of shooting by us and one other fleet should take them down. Who's with me? 
The 3rd DD and only the 3rd DD should engage the 1st Hertak, because the 3rd DD and only the 3rd DD has exactly enough strength to destroy the 1st Hertak all by itself. What an introduction that will be for the only fleet (besides the Cyrvans) that hasn't engaged yet. See:
3rd DD Fleet:
- Fighter attack strength: 17+8=25 (18-1)
- Capital attack strength: 16+9+4 barrage =
29 (17-1)
- Fighters at 100% Strength, 2nd Gen
- Capital ships at 100% Strength
- Morale: Low
vs.
1st Hertak Fleet:
Fighter attack strength: 7+5=12 (22)
Capital attack strength: 9+4=13 (30)
Fighters at 32% Strength
Capital ships at
29% Strength
Morale: Normal
I also would advise another Hertak dogpile, like so:
2nd LSF Fleet:
- Fighter attack strength: 22+8=30 (19+2+1)
- Capital attack strength: 15+11=26 (14+1)
- Fighters at 100% Strength, 3rd Gen
- Capital ships at 100% Strength
- Morale: High
2nd DD Fleet:
- Fighter attack strength: 16+8=24 (18+2+2)
- Capital attack strength: 16+8=24 (17+2)
- Fighters at 78% Strength, 3rd Gen
- Capital ships at 80% Strength
- Morale: Very High
- Barrage on Cooldown, Available again on Turn 8
- Inspirational Leader
3rd SF Fleet:
- Fighter attack strength: 17+8=25 (18+2+1)
- Capital attack strength: 15+9=24 (18+1)
- Fighters at 75% Strength, 3rd Gen
- Capital ships at 76% Strength
- Morale: High
vs.
2nd Hertak Fleet
Fighter attack strength: 22+15=37 (22)
Capital attack strength: 30+11=41 (30)
- Fighters at 100% Strength
- Capital ships at 100% Strength
Morale: Normal
Total damage inflicted:
Fighters - 79
Capital ships - 74
Total damage received per allied fleet:
