To what possible use can cavalry be put? Can it be used in attack?
Not against trenches; that is better done by infantrymen following up
gunfire. Can it be used against broken infantry in the open? Not if the
enemy has one or two machine guns covering their retreat. Against expose
infantry the swooping aeroplane with a machine gun is far more deadly
and more difficult to hit. Behind it your infantry can follow to receive
surrenders; in most circumstances they can come up on cycles if it is
a case of getting up quickly across a wide space. Similarly for
pursuit the use of wire and use of the machine gun have abolished the
possibility of a pouring cavalry charge. The swooping aeroplane does
everything that cavalry can do in the way of disorganising the enemy,
and far more than it can do in the way of silencing machine guns. It can
capture guns in retreat much more easily by bombing traction engines
and coming down low and shooting horses and men. An ideal modern
pursuit would be an advance of guns, automobiles full of infantry, motor
cyclists and cyclists, behind a high screen of observation aeroplanes
and a low screen of bombing and fighting aeroplanes. Cavalry _might_
advance across fields and so forth, but only as a very accessory part of
the general advance....

And what else is there for the cavalry to do?

It may be argued that horses can go over country that is impossible for
automobiles. That is to ignore altogether what has been done in this war
by such devices as caterpillar wheels. So far from cavalry being able to
negotiate country where machines would stick and fail, mechanism can now
ride over places where any horse would flounder.

I submit these considerations to the horse-lover. They are not my
