Karnath: A stronghold in difficult terrain is a soldier’s advantage. Choose a place where the land forces the enemy into choke points – cliffs, ravines, or a narrow pass. Build walls that match the slope, use stone and earth to create natural bulwarks, and leave only a few controlled openings for your troops to fire through. Keep the supply lines short and hidden, so you can move men and ammo without exposing yourself. Train your men to use the terrain as a shield, not just a backdrop. Discipline is key; every soldier must know his exact spot and the line of sight. That way, even a larger force will be forced to waste time and resources, giving you the upper hand.
