There is no picture showing the bosses. On the map, you will see three "rooms" that look like they are on the edge / outside of the barracks. When you first enter the barracks, stay along the wall "on the right side of the room" and it will lead you right to the first boss / or side room.
After you defeat him, when you come out of the side room, again "stay along the right side of the wall" and it will lead you to the next room.
Do this each time, and you will finally reach Prince Aka.
