ROLE OF HORSE ARTILLERY*

amount of mobility sufficient for its efficiency—-it must be combined 
with the greatest possible development of shell-power. When, therefore, 
it is found that the duties of the horse artillery can be performed by 
field batteries, it is reasonable to assume either that the mobility of the 
horse artillery or the shell-power of the field batteries is capable of 
further development. From this we are brought to the conclusion that 
to equip field batteries with a horse artillery gun is to throw away 
wantonly the greatest advantage of artillery in the field-—weight of 
metal. 
In a word, then: while the cavalry divisions should always be 
accompanied by a certain proportion of horse artillery, horse artillery 
should only be attached to infantry divisions when operating on ground 
where field batteries cannot follow. At least half the artillery of the 
advanced or rear guard, and the greater part of the corps artillery, 
should consist of horse artillery. 
In the varying phases of the battle, horse artillery must reinforce the 
field batteries, and the field batteries the horse artillery, as circum¬ 
stances demand; but some of the horse batteries of the corps artillery 
should be kept in hand for the critical stages of the attack or defence, 
“ like greyhounds in the leash.” * 
Finally, let us banish from our minds all bygone theories of cavalry 
artillery and infantry artillery—square triangles and round triangles— 
and never for a moment forget that if six guns are required for the attack 
or defence of a certain point, the question to be considered is not what 
troops are fighting at that point, cavalry or infantry, but what is the 
largest calibre that can be effectively employed in the attack or defence 
of the given point ?
