es each will have only fifteen brigades in the first line, while
the same thirty brigades formed in ten divisions of three brigades each
may have twenty brigades in the first line and ten in the second. But it
then becomes necessary to diminish the number of divisions and to have
but two in a corps,--which would be a faulty arrangement, because the
corps is much more likely to be called upon for independent action than
the division.]

[Footnote 42: Every army has two wings, a center, and a reserve,--in
all, four principal subdivisions,--besides accidental detachments.

Below are some of the different formations that may be given to
infantry.

1st. In regiments of two battalions of eight hundred men each:--

Div's. Brig's. Batt'ns. Men. Four corps of two divisions each, and
three divisions for detachments.................. 11 = 22 = 88 =
72,000

Four corps of three divisions each, and three divisions for
detachments................... 15 = 30 = 120 = 96,000

Seven corps of two divisions each, and one corps for
detachments....................... 16 = 32 = 128 = 103,000

2d. In regiments of three battalions, brigades of six battalions:--

Div's. Brig's. Batt'ns. Men. Four corps of two divisions each,
besides detachments,............................... 11 = 22 = 132
105,000

Four corps of three divisions each, besides
detachments................................ 15 = 30 = 180 = 144,000

Eight corps of two divisions each............ 16 = 32 = 192 =
154,000

If to these numbers we add one-fourth for cavalry, artillery, and
engineers, the total force for the above formations may be known.

It is to be observed that regiments of two battalions if eight hundred
men each would become very weak at the end of two or three months'
campaigning. If they do not consist of three battalions, then each
battalion should contain one thousand men.]

Napoleon I.--Translators.]

[Footnote 44: As the advanced guard is in presence of the enemy every
day, and forms the rear-guard in retreat, it seems but fair at the hour
of battle to assign it a position more retired than that in front of the
line of battle.]

[Footnote 45: This disposition of the cavalry, of course, is made upon
the supposition that the ground is favorably situated for it. This is
the essential condition of every well-arranged l
