Step-by-step explanation:
In the absence of fighting, Arthur says that the military can prevent the enemy from engaging them by throwing something odd and unaccountable in their way.
Arthur also suggests that if the troops are not overburdened with money, it is not because they have a distaste for riches, but rather to avoid them becoming attached to wealth and losing their effectiveness as soldiers.
Additionally, Arthur emphasizes the importance of the general being able to mystify the officers and men with false reports and appearances, keeping them in ignorance and preventing the enemy from anticipating their plans.
