(1.) In deployed lines.
(2.) Lines of regiments, in columns of attack doubled on the centre.
(3.) A mixed formation of lines and columns.
(4.) Echelons of lines or columns; or--
(5.) Deep columns.
2. _Deployed lines_ are not objectionable in principle. They are often
not advisable; but are sometimes necessary.
But long, continuous lines should always be avoided; being unfavorable
to rapid manoeuvring, which cavalry is constantly called upon to
execute in the field.
3. Cavalry has, in its horses, an unreasoning element, which is not
controllable, like men; and is therefore much more easily thrown into
disorder than infantry. For this reason, when deployed, it should always
be _in two lines_; the second behind the first; the first line deployed,
and the second in columns of squadrons by platoons. There should be also
a reserve at a few hundred paces behind the second line.
The second line should be near enough to the first to be able to support
it, if checked; but not so near as to partake in its disorder, if
repulsed.
4. Cavalry should be always _in column_ when expecting to manoeuvre,
or to be called on to make any rapid movement; this being the formation
best adapted for celerity.
