 Scipio concentrated on restoring discipline by forbidding luxuries the troops had become accustomed to, through regular tough exercises (all-day marches, building camps and fortifications and then demolishing them, digging ditches and then filling them up, and the like) and by enforcing regulations strictly.When he thought that the army was ready he encamped near Numantia.He did not proceed along the shorter route to avoid the guerrilla tactics the Numantines were good at.
