1st Battle American Campaign Red Zone Defeat green objectives why?

[doublebuck]

Just started a new hard American Campaign, 1st battle, I capture 1 enemy ship and sail it to the red safe zone along with my two ships for they are taking too much damage from the remaining enemy so we retreat and at the beginning of the battle the game says we can't win the fight so they show us a red zone.  I have green objectives so I should get a win but why did the game give me a defeat and end of war?  F11, I am playing version 8.23 REV 35062
