A short time after we quitted our second position, the Russian cavalry showed themselves again. General Szymanowski remained, with two companies of the 7th regiment of the line, to defend the passage of the third village against the enemy, and to give time to our cavalry to take a third position. This general, for nearly an hour, resisted the attack of a strong force of cavalry, but commenced evacuating the position on the approach of considerable bodies of the Russian infantry, withdrawing through the forests. The Russian cavalry, seeing that the village was abandoned by our infantry, began to debouch through it. It was an act of the greatest imprudence in the Russian cavalry, unsupported by either infantry or artillery, to advance thus upon a plain surrounded by forests, in which they might have supposed infantry, and even cavalry, to be concealed. Two squadrons of our cavalry commenced a fire in order to harass them, and draw them on to the middle of the plain. Afterwards, those two squadrons wheeling about, laid open the Russian cavalry to the fire of our artillery, which was posted on a little elevation and concealed by brush-wood. This fire of our artillery was effective. The enemy's cavalry began to waver. General Szymanowski observing this, ordered an immediate attack by our whole cavalry, consisting of twelve squadrons. This attack was made with great impetuosity. Sixteen hussars, with two officers, were taken prisoners, and forty or fifty were left, killed or wounded, on the field. After this, the corps recommenced its march to Worna, leaving two battalions of the 7th regiment of infantry, as a rear-guard, in the forests which border on that road. The successes which we had thus obtained in our three first positions were over the advanced guard of the enemy; but in the fourth position, arranged by the brave and skilful colonel Koss, and in which our successes were even greater, we had to encounter the whole body of the Russian forces in Lithuania, which, according to some of our prisoners, were to be estimated at 18,000, and by others at 25,000 men, with 36 pieces of artillery, under the command of the several Russian generals, Kreutz, Tolstoy, Szyrman, Delinghausen, and Saken. The town of Worna is surrounded by two large lakes, in such a manner that the only communication with that town to the west, is by a neck of land, separating the extremities of those two lakes. The town is situated upon an elevated ground, which overlooks the whole vicinity. On our left wing was a forest, that reached one of the lakes. This forest was occupied by two battalions of infantry. Our right wing leaned upon the other lake. All our artillery remained in the centre, and occupied the heights near Worna.
