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.
