What's the Worst that could happen?

Much more rare and probably quite interesting would be your biggest stalemates.

In CB#1, I once had a big defense net of satellites and ships on the enemy side of a warppoint. An Alliance force attacked with 30 ships, which at the time was about a quarter of both our militaries (small quadrant).

Roughly 30 on 30 at the start. I had way too many missile ships, and the Alliance force had way too many point defense ships
After that turn was finally processed, we both had 25 ships left in the sector... according to the supply drain, my forces had fired almost a thousand missiles, and had run right out of ammo.

The enemy fleet had suffered some damage to most of their attack ships, and had to fall back a turn later.
My forces had to fall back for repairs as well as for desperate resupply as soon as the enemy had backed off.
