One more person backing Rollo.

The only "retreat" option I wold prefer to have is in the combat strategies.

Something along the lines of "If my shields (or hull) are below ## percent, then switch strategy to don't get hurt"

Your raiders could harrass a slower enemy, and then fall back to the edge of the combat map before they get severely damaged.

Retreating from the combat map should only happen after 30 turns. If your ships had the ability and the orders to retreat, they wouldn't have entered combat in the first place, since they would have stayed away from enemies on the strategic map.
