Presently along the straight road the black column of the enemy could be seen. They were advancing in a heavy mass, some forty men abreast, and were preceded at a distance of 300 yards by an advance guard of 200 men. When distant some 400 yards from them the midshipmen observed the advance guard halt, and guessed that an obstacle of some sort or other across the road had been made out. A mounted officer rode back from the advance guard to the main body, and was there joined by several other mounted men. After some conversation a movement was seen in the column. A mounted officer rode back, and as he did so the column divided, leaving a passage in the centre of the road.
There was a long pause, and then the lads could see the Russian guns coming through the line. They halted and formed across the road half-way between the main body and the advance guard, and, unlimbering, prepared to open fire upon the unknown obstacle in their front. The midshipmen had arranged with Stanislas that, as it would be difficult for the parties on the flank of the Russian column to distinguish between the sound of the enemy's guns and their own, a white handkerchief should be hoisted on a long pole when they themselves opened fire, and a chain of men were placed along back in the wood to repeat the signal down to the spot where the Poles were lying ready for attack.
The Russians opened fire over the heads of their advance guard, who lay down in the road. The shot for the most part either struck the slope or flew overhead, very few striking the upper part of the battery face, which was alone exposed to their fire. For five minutes the Russians continued to fire. Then, deceived by the absolute silence which reigned, and supposing the obstacle was an accidental one, or that the insurgents had retired, the guns were limbered up, the advance guard again moved forward, and the main column marched on close behind the guns.
The whole of the 200 men who had been placed behind the barricade were armed with muskets, and each hidden behind the leafy screen rested his piece on a branch, and prepared to pour his fire into the column as it advanced. It was not until the advance guard was within fifty yards of them that the lads, who had themselves trained the guns to sweep the road, gave the signal, and the silence was broken by the roar of the two guns loaded to the muzzle with grape-shot. The effect was tremendous. Two lanes were literally mown through the ranks of the Russian infantry, the shot which flew high doing terrible execution among the artillery behind them.
The echoes had not died away when a tremendous fire of musketry was opened by the Poles hidden behind the abattis. More than half of the advance guard fell under that terrible discharge, and the artillery crowded behind them fell into confusion.
The Russian officers strove by voice and example to gather the survivors of the advance guard together; but the consternation which the slaughter had caused was heightened by the sound of a tremendous yell far behind, followed by a steady roll of musketry, showing that the column was hotly engaged there also. The artillery attempted to unlimber and to bring their guns to bear again, but the confusion that prevailed in the crowded spot rendered this next to impossible, and long before it could be accomplished the iron hail again swept through the ranks, and two rattling volleys from their invisible foes behind the flanking abattis again flashed out. The advance guard were annihilated, the artillery in confusion, but the general commanding the main column pushed his men on through the frightened horses of the artillery, and, opening a heavy musketry fire on their unseen foes, pressed forward to the assault.
The conflict now became a desperate one. The midshipmen fired their guns alternately as fast as they could load, the Poles working as steadily and coolly as if they had been long-trained artillerymen. Several times the Russians advanced to within twenty yards of the defences, but each time, shattered by the fire of grape-shot and by the storm of bullets from the abattis, they recoiled. In vain they flung themselves upon the trees and tried to hew a way through them. In vain the officers called upon them to gather themselves together and carry the battery at a rush. Receiving no aid from their own artillery, which, mingled in the throng of infantry, were helpless, shaken by the shouts of the assailants, and by the battle raging in their rear which told them their retreat was menaced, the Russians lost heart and began to fall back. Then, retaining only fifty men as a guard to the battery, the midshipmen ordered the rest of the defenders of the abattis to move forward among the trees on the flanks of the Russians, keeping up a constant fire, until they joined the main body in their attack on the Russian rear.
In the battery now they could see little of what was going forward. The woods were full of dense smoke. The whole Russian column as it fell back was maintaining a wild fire at random into the bushes around them.
But though the lads could see nothing, the road in front afforded them a sure guide for their aim, and ceaselessly the guns kept up their fire into the retreating mass of Russians.
For half an hour the roar of guns continued unabated, and then, as it died away, the triumphant shouts of the Pole told them that the victory was won, and that the Russian column, defeated and shattered, had retired from the forest and gained the open country beyond. Then the defenders of the battery raised an answering cheer to their friends in the distance, and, exhausted with their exertions, threw themselves on the ground.
