troops into line at the moment of attack. Such was his order of march at
Prague, Kollin, Rosbach, Leuthen, Zornsdorf, and Kunersdorf. The
following is one of Frederick's orders respecting marches, (October 2d,
1760.)

"The army will, as usual, march in three columns by lines. The first
column will consist of the first line; the second, of the second line;
and the third, of the reserve. The wagons, and hospital wagons, of
regiments, will follow their corps. The batteries of heavy calibre will
follow the infantry brigades to which they are assigned. On passing
woods, the regiments of cavalry will march between two infantry corps."

"Each column will have a vanguard of one light battalion and ten
squadrons of hussars or dragoons. They will be preceded by three wagons
carrying plank-bridges. The rear-guard is charged with taking up these
bridges after the army has defiled over them."

"The parks will be divided among the columns, to avoid the embarrassment
resulting from a great many wagons being together in a body."

"If any thing should happen to the second and third columns, the king
will be instantly apprized of it; he will be found at the head of the
first column. Should any thing occur to the rear-guard, the same will be
instantly communicated to Lieutenant-general Zeithen, who will be with
the rear-guard of the first column."

"The officers will take care that the soldiers march with equal step,
and that they do not stray to the right or left, and thus uselessly
fatigue themselves and lose their distances."
