The stronger men will be in front, the jaded ones will fall behind,
and on this plan only one-tenth of your army will reach its destination.
For 罷, see II. § 14. The moral is, as Ts‘ao Kung and others point
out: Don’t march a hundred _li_ to gain a tactical advantage,
either with or without impedimenta. Manœuvres of this description
should be confined to short distances. Stonewall Jackson said:
“The hardships of forced marches are often more painful than the
dangers of battle.” He did not often call upon his troops for
extraordinary exertions. It was only when he intended a surprise,
or when a rapid retreat was imperative, that he sacrificed
everything to speed.[171]
