The invasion has been foiled.  The League has had time to produce replacement vessels of the super dreadnought class.  This marks the end of the J’nan-Nath Alliance and their expansion plans.
Congratulations

The enemy ranks have been decimated.  Less than a third remain.  You will be given a hero’s burial.

It’s been a hard battle with inconclusive results.  Your sacrifice has been worthy but may not be definitive.

DEFEAT! The enemy fleets will conquer the League! This marks the end of the League and the civilized free galaxy!  Posterity will curse your name as they suffer under the whip of the J’nan slime demons!
