I am stuck in the part where Quintain and Trent just got past the first group of Rheinlanders, and have to fight some more near the Leeds jump hole. It says to "cover" Quintain's ship, and I don't know how to do that besides killing all the fighters first. But Quintain always gets killed before I can get the fighters, and the game ends. Is there a way to protect Quintain long enough to kill off the enemy ships? Thanks!
