A Commander's Guide to Fortifying with the Land

A wall of stone can be broken, an army can be routed. But he who makes an ally of the mountains and rivers commands a force that never tires and cannot be bribed. To expend endless labor on artificial walls while ignoring the fortress nature provides is the mark of a foolish commander. I will teach you to see the land not as a place to build, but as the foundation of your defense itself. By understanding terrain, you force the enemy to fight on your terms, exhausting his strength before the first arrow is loosed.
You will need:
A commanding knowledge of your local terrain, gained through meticulous scouting.
Scouts or simple surveying tools for measuring distances and elevations.
Basic digging implements: shovels, picks, and baskets for moving earth.
Cutting tools: axes and saws for clearing trees and shaping timber.
A disciplined workforce that understands the strategic objective of their labor.
A preliminary plan of the intended settlement and its defensive perimeter.
1. Assess and Seize the High Ground
The wise commander occupies high ground. Identify the highest defensible point in your territory. This will be your citadel or primary watch post. It offers superior observation and forces any attacker to fight uphill, expending his energy while you conserve yours. From here, you see all and control the approaches.
2. Identify Natural Barriers and Choke Points
A river, a cliff, a dense swamp, or a rocky gorge are walls that require no building. Map these features with care. Locate the narrow passages or 'choke points' an enemy must traverse to approach you. These are the places where a few can stand against many, and where your victory can be assured at little cost.
3. Integrate Water as a Moat and Obstacle
Do not merely build near water; command it. Divert a stream to create a moat on your weakest flank. A marshy or flooded area in front of your position will mire attackers, making them slow, vulnerable targets for your archers. Water is a defense that repairs itself and never sleeps.
4. Utilize Forests for Concealment and Deception
A dense forest is not a liability, but an instrument of war. Leave a thick belt of woods intact around your perimeter. It conceals your numbers and structures, confuses enemy scouts, and slows any organized assault into a chaotic crawl. From within, you can create hidden paths and kill zones known only to you.
5. Shape the Earth to Your Will
Where the ground is flat, you must create your own advantages. Use the earth from digging a ditch to build a corresponding rampart or berm behind it. This simple act doubles the effective height of your obstacle with a single effort. The ditch impedes the advance; the rampart protects your defenders.
6. Position Entrances with Cunning
A gate is a necessary weakness. Never place it where an enemy has a direct, easy approach. Position your entrance so that attackers must expose their unshielded flank to your defenders on the walls as they draw near. A winding or angled approach forces the enemy into disorder before they ever reach your door.
7. Prepare for Both Siege and Sortie
A fortress without a way out is a tomb. A wise general always provides for a hidden line of retreat or a secret gate for launching surprise attacks. This allows for flexibility, the gathering of intelligence, or harassing a besieging foe. To be unconquerable is a matter of defense; the opportunity of defeating the enemy is provided by the enemy himself.
