He employed discreet and faithful persons, living near the enemy's lines, to watch their motions and give him immediate intelligence.

He established signals throughout the lines; so that, whether by night or by day, instant notice might be had of an attack or movement of the enemy. He enforced various regulations for concealing his position and force from the enemy.
