Ammunition column
An ammunition column consists of
military vehicles carrying gun and S.A. ammunition for the
combatant unit to which the column belongs. Thus the ammunition
columns of a division, forming part of the brigades of field
artillery, carry reserve ammunition for the guns, the machine
guns of the infantry and the rifles of all arms. Generally
speaking, the ammunition column of each of the artillery
brigades furnishes spare ammunition for its own batteries and
for one of the brigades of infantry. All ammunition columns
are officered and manned by the Royal Artillery. They are
not reserved exclusively to their own brigades, divisions,
&c., but may be called upon to furnish ammunition to any unit
requiring it during an action. The officers and men of the
R.A. employed with the ammunition column are, as a matter of
course, immediately available to replace casualties in the
batteries. Teams, wagons and materiel generally are also
available for the same purpose. The horse artillery, howitzer
and heavy brigades of artillery have each their own ammunition
columns, organized in much the same way and performing similar
duties. The ammunition column of the heavy brigade is
divisible into three sections, so that the three batteries,
if operating independently, have each a section at hand
to replenish the ammunition expended. The horse artillery
brigade ammunition columns carry, besides S.A.A. for all
corps troops other than artillery, the reserve of pom-pom
ammunition. In action these columns are on the battlefield
itself. Some miles to the rear are the divisional and corps
troops columns, which on the one hand replenish the empty
wagons of the columns in front, and on the other draw fresh
supplies from the depots on the line of communication.
These also are in artillery charge; a divisional column is
detailed to each division (i.e. to replenish each set of
brigade ammunition columns), and the corps troops column
supplies the columns attached to the heavy, howitzer and
horse artillery brigades. The ammunition thus carried
includes ordinarily seven or eight kinds at least. S.A.A.,
field, horse, howitzer and heavy gun shrapnel, howitzer and
heavy gun lyddite shells, cartridges for the four different
guns employed and pom-pom cartridges for the cavalry, -- in
all twelve distinct types of stores would be carried for a
complete army corps. Consequently the rounds of each kind
in charge of each ammunition column must vary in accordance
with the work expected of the combatant unit to which it
belongs. Thus pom-pom ammunition is out of place in the
brigade ammunition columns of field artillery, and S.A.A. is
relatively unnecessary in that attached to a heavy artillery
brigade. Under these circumstances a column may be unable to
meet the particular wants of troops engaged in the vicinity;
for instance, a cavalry regiment would send in vain to a heavy
artillery ammunition section for pom-pom cartridges. The point
to be observed in this is that the fewer the natures of weapons
used, the more certain is the ammunition supply. (C. F. A.)
The first projectiles fired from cannon were the darts and
stone shot which had been in use with older weapons. These
darts ("garros") had iron heads or were of iron wrapped with
leather to fit the bore of small guns, and continued in use up
to nearly the end of the 16th century. Spherical stone shot
were chosen on account of cheapness; forged iron, bronze and
lead balls were tried, but the expense prevented their general
adoption. Further, as the heavy metal shot necessitated the
use of a correspondingly large propelling charge, too great
a demand was made on the strength of the feeble guns of the
period. Stone shot being one-third the weight of those of
iron the powder charge was reduced in proportion, and this
also effected an economy. Both iron and stone shot were
occasionally covered with lead, probably to preserve the interior
of the bore of the gun. Cast iron, while known in the [[14th
century]], was not sufficiently common to be much used for the
manufacture of shot, although small ones were made about that
time. They were used more frequently at the latter part of
the following century. Towards the end of the 16th century
nearly all shot were of iron, but stone shot were still used
with guns called Petrieroes (hence the name) or Patararoes,
for attacking weak targets like ships at short range.
Case shot are very nearly as ancient as spherical shot.
They can be traced back to the early part of the 15th century,
and they have practically retained their original form up to
the present date. They are intended for use at close quarters
when a volley of small shot is required. With field guns they
are not of much use at ranges exceeding about four hundred
yards; those for heavy guns are effective up to one thousand
yards. In the earlier forms lead or iron shot were packed
in wood casks or in canvas bags tied up with twine like the
later quilted shot. In the present type small shot
are placed in a cylindrical case of sheet iron, with iron
ends, one end being provided with handles. For small guns
the bullets are made of lead and antimony -- like shrapnel
bullets -- while for larger calibres they are of cast iron
weighing from two ounces to three and a half pounds each.
Grape shot is now obsolete. It consisted generally of three
tiers of cast-iron balls separated by iron plates and held in place
by an iron bolt which passed through the centre of the plates.
There was also another type called quilted shot which consisted
of a number of small shot in a canvas covering tied up by rope.
Chain shot, in the days of sailing ships, was much in favour as
a means of destroying rigging. Two spherical shot were fastened
together by a short length of chain. On leaving the gun they
began gyrating around each other and made a formidable missile.
Red-hot shot were invented in 1579 by Stephen Batory, king of
Poland. They were used with great effect by the English
during the siege of Gibraltar, especially on the 13th of
September 1782, when the French floating batteries were
destroyed, together with a large part of the Spanish fleet.
Martin's shell was a modified form; here a cast-iron
shell was filled with molten cast iron and immediately
fired. On striking the side of a ship the shell broke up,
freeing the still molten iron, which set fire to the vessel.
