"Bravo for the cannoneers!" cried Bossuet.
And the whole barricade clapped their hands.
A moment later, squarely planted in the very middle of the street,
astride of the gutter, the piece was ready for action. A formidable pair
of jaws yawned on the barricade.
"Come, merrily now!" ejaculated Courfeyrac. "That's the brutal part of
it. After the fillip on the nose, the blow from the fist. The army is
reaching out its big paw to us. The barricade is going to be severely
shaken up. The fusillade tries, the cannon takes."
"It is a piece of eight, new model, brass," added Combeferre. "Those
pieces are liable to burst as soon as the proportion of ten parts of tin
to one hundred of brass is exceeded. The excess of tin renders them too
tender. Then it comes to pass that they have caves and chambers when
looked at from the vent hole. In order to obviate this danger, and
to render it possible to force the charge, it may become necessary
to return to the process of the fourteenth century, hooping, and to
encircle the piece on the outside with a series of unwelded steel bands,
from the breech to the trunnions. In the meantime, they remedy this
defect as best they may; they manage to discover where the holes are
located in the vent of a cannon, by means of a searcher. But there is a
better method, with Gribeauval's movable star."
"In the sixteenth century," remarked Bossuet, "they used to rifle
cannon."
"Yes," replied Combeferre, "that augments the projectile force, but
diminishes the accuracy of the firing. In firing at short range,
the trajectory is not as rigid as could be desired, the parabola is
exaggerated, the line of the projectile is no longer sufficiently
rectilinear to allow of its striking intervening objects, which is,
nevertheless, a necessity of battle, the importance of which increases
with the proximity of the enemy and the precipitation of the discharge.
This defect of the tension of the curve of the projectile in the rifled
cannon of the sixteenth century arose from the smallness of the charge;
small charges for that sort of engine are imposed by the ballistic
necessities, such, for instance, as the preservation of the
gun-carriage. In short, that despot, the cannon, cannot do all that
it desires; force is a great weakness. A cannon-ball only travels
six hundred leagues an hour; light travels seventy thousand leagues a
second. Such is the superiority of Jesus Christ over Napoleon."
