The case disintegrated as
it emerged from the muzzle to spread its projectiles in a spray pattern,
shotgun fashion. The third was spherical shell: hollow cast-iron globes
filled with gunpowder and fitted with a fuse which, if cleverly adjusted,
could be configured to explode just over the heads of advancing infantry.
(In 1804, it would evolve into the famous shrapnel shell.)
Solid shot accounted for about 70 percent of the ammunition
carried by the artillery and was used for medium-range fire. Ranges and
lethality varied according to the size of ball and powder charge. William
Müller, an officer in the King’s German Legion, made extensive tests
of artillery accuracy which he published in The Elements of the Science
of War (1811). Müller’s tests, although from a slightly later date than
the War of Independence, would have been applicable to the earlier
time frame. As with all such tests, there is some dislocation from the
realities of the battlefield, but they are nevertheless useful as a range
finder of lethality. For example, the 6-pounder (the workhorse of field
artillery) firing at a cloth target six feet high by thirty feet wide (roughly
representing a company of infantry) scored 100 percent hits at 520 yards
and 31 percent hits at 950 yards. At 1,200 yards, however, it scored only
17 percent hits. Müller’s test does not quite tell the whole story because
gunners firing a round shot tried to get two or even more bites at the
cherry through ricochet: the effect of a cannonball bouncing before
coming to rest. A 6-pounder might have a range of about 1,200 yards,
but the ball had several phases of lethality over that distance. At zero
degrees elevation (parallel with the ground) the first bounce (“graze”)
would have been at about 400 yards; it would then travel for another
400 yards at shoulder height before making its second graze, and then
on for a further 100 yards at about three feet from the ground before
rolling to a halt. The knack was to pitch the ball just in front of the
enemy’s first rank and have it skip and rise through the subsequent
ranks. If the ground was hard and stony, each graze would kick up
splinters, which, in their turn, became secondary projectiles. Even in its
last phase, a rolling ball could be deceptively harmful. There are many
instances of men being badly wounded, even killed, by trying to “catch”
