Know Your Battlefield
Sun Tzu says:
Ground may be classified according to its nature as accessible, entangling, temporizing, constricted, precipitous and distant.
Ground which both we and the enemy can traverse with equal ease is called accessible. On such ground, he who first takes high sunny positions, and keeps his supply routes unimpeded can fight advantageously. Ground easy to reach but difficult to exit is called entangling. The nature of this ground is such that if the enemy is unprepared and you sally out, you may defeat him. But, if the enemy is prepared for your coming, and you fail to defeat him, then, return being difficult, disadvantages will ensue.
Ground equally disadvantageous for both the enemy and ourselves to enter is called temporizing. This ground is such that even though the enemy offers us an attractive bait, it will be advisable not to go forth but march off. When his force is halfway out because of our maneuvering, we can strike him with advantage. With regard to the constricted ground, if we first occupy it, we must block the narrow passes with strong garrisons and wait for the enemy. If the enemy first occupies such ground, do not attack him if the pass in his hand is fully garrisoned, but only if it is weakly garrisoned.
With regard to the precipitous ground, if we first occupy it, we must take a position on the sunny heights and await the enemy. If he first occupies such ground, we should march off and do not attack him. When the enemy is situated at a great distance from us, and the terrain where the two armies deploy is similar, it is difficult to provoke battle and unprofitable to engage him.
These are the principles relating to six different types of ground. It is the highest responsibility of the general to inquire into them with the utmost care. Conformation of the ground is of great assistance in the military operations. It is necessary for a wise general to make correct assessments of the enemy's situation to create conditions leading to victory and to calculate distances and the degree of difficulty of the terrain. He who knows these things and applies them to fighting will definitely win. He who knows them not, and, therefore, is unable to apply them, will definitely lose.
