We can form a single united body, while the enemy must split up into
fractions. Hence there will be a whole pitted against separate parts
of a whole,
The original text has 以敵攻其一也, which in accordance with the
_T‘ung Tien_ and _Yü Lan_ has been altered as above. I adopt the
more plausible reading of the _T‘u Shu_: 是以十攻其一也, in spite of
having to refer 十 to ourselves and not to the enemy. Thus Tu Yu
and Mei Yao-ch‘ên both regard 十 as the undivided force, consisting
of so many parts, and 一 as each of the isolated fractions of the
enemy. The alteration of 攻 into 共 can hardly be right, though the
true text might conceivably have been 是以十共攻其一也.
which means that we shall be many to the enemy’s few.
