But we had two other allies besides the night. Just where the enemy had pushed his right flank to the river was the mouth of a wide bayou, and here two gunboats had taken station. They too were of the toy sort, plated perhaps with railway metals, perhaps with boiler-iron. They staggered under a heavy gun or two each. The bayou made an opening in the high bank of the river. The bank was a parapet, behind which the gunboats crouched, firing up the bayou as through an embrasure. The enemy was at this disadvantage: he could not get at the gunboats, and he could advance only by exposing his flank to their ponderous missiles, one of which would have broken a half-mile of his bones and made nothing of it. Very annoying this must have been--these twenty gunners beating back an army because a sluggish creek had been pleased to fall into a river at one point rather than another. Such is the part that accident may play in the game of war. As a spectacle this was rather fine. We could just discern the black bodies of these boats, looking very much like turtles. But when they let off their big guns there was a conflagration. The river shuddered in its banks, and hurried on, bloody, wounded, terrified! Objects a mile away sprang toward our eyes as a snake strikes at the face of its victim. The report stung us to the brain, but we blessed it audibly. Then we could hear the great shell tearing away through the air until the sound died out in the distance; then, a surprisingly long time afterward, a dull, distant explosion and a sudden silence of small-arms told their own tale.
