Kill off the lurkers in the base. It is now yours. Take it and make it into a fully functional base. Build defenses, then build up a large army for the attack.

Head north and east until you find their base. Take it out. Leave the fiends where they are. Now if you head NW and NE you will get to the main base. Attack it with all your strength to take it out.
