The gun was fired rapidly again, and the men saw that the effect was good; the red line of their enemy had been shattered once more. The corporal glanced a little to the left, and said, in an unchanged voice:
"A cavalry charge is coming; stand steady!"
The red line of infantry was suddenly blotted out, and in its place a line of horsemen rose out of the smoke. They were riding at a gallop, firing from their pistols, their sabres ready for the swinging blow when the charge was driven home, a swelling wave, edged with fire and steel. It was a glittering and magnificent sight.
The boys about the gun looked anxious at the sight of the cavalry, but the corporal was calm.
"Load with grape, triple charges!" he said, and his voice cracked louder and sharper than ever.
The grape, triple charges, was rammed into the twelve-pounder, and the wonderful machine that handled the gun increased its speed. The British cavalry galloped into a stream of fire. The gun was hidden from them by the incessant blaze and smoke of its discharges, and the triple loads of grape whizzed among them, killing horses and horsemen, destroying the precision of their ordered lines, crumpling up those in front, and heaping the dead in the way of those behind. But the unslain horsemen galloped on, and always before them roared the engine of death, the gun, and always about them whistled the showers of grape. Presently they were into the flame and the smoke, and before them rose the gun and its detachment.
"Stretch prolonge ropes!" shouted the corporal to his men.
The drivers cracked their whips over the horses, and whirled the caisson and the limber chest about, bringing them, horses and all, into line with the piece, and in a moment, heavy ropes were stretched from the cannon to the limber chest, and from the limber chest to the caisson, and the fighting men were crouching in their appointed positions between the wheels, and around the gun, holding in hand their pistols and artillery swords, short, heavy weapons with which they could slash as with axes. The cavalry company was charging upon a breastwork held by an armed force.
"Let 'em have it with the pistols!" cried the corporal to his men.
The pistols began to crack, and more holes appeared in the charging lines of horsemen. When a trooper was hit hard in the breast or shoulder, up went his hands, and he fell back from his horse; if struck in the limbs, he fell forward and rolled off. Some horses that had lost their riders kept place in the charge and galloped on. Two or three others turned to one side, and ran about, neighing with fear and alarm, but would not leave the field. All sprang aside when they came to a wounded or dead man lying on the ground.
