The Art of War (孫子兵法), Terrain 地形篇

隘形者我先居之必盈之以待敵

With regard to narrow passes , if you can occupy them first,

let them be strongly garrisoned and await the advent of the enemy.

Lionel Giles's notes

Capt. Calthrop says: “Defiles, make haste to occupy.” But this is a conditional clause, answering to 若敵先居之 in the next paragraph.

Because then, as Tu Yu observes, 皆制在我然後出奇以制敵 “the initiative will lie with us, and by making sudden and unexpected attacks we shall have the enemy at our mercy.” The commentators make a great pother about the precise meaning of 盈, which to the foreign reader seems to present no difficulty whatever.
