Due to the constant attacks from some unknown enemy force, the Alliance has decided to move its operations off planet. Unfortunately, details of their departure are leaked to the enemy, who have placed blockades at the exit points for each convoy's exit point. Communications between the convoys are disrupted and jammed. Captain Bill Decker is command of the frontier base's convoy. His blockade is the most heavily guarded. Looks like they'll have to just blast their way out.
