This day, which may be called one of the most brilliant in our war, cost the enemy, besides his killed and wounded, two thousand prisoners, with more than twenty officers, four standards, ten pieces of cannon, some hundred horses, and about thirty chests with ammunition, with officers' baggage, &c. The prince Wirtemberg with the remains of his corps retreated by forced marches to the small town of Granica, where he repassed the Vistula and reached Pulawa. Thus, by a single battle, the whole country on this side of the Vistula was cleared of the presence of the enemy. General Dwernicki permitted to his corps, who were really much exhausted by fighting and marching, to repose by a slow march as far as Kozienice, where he remained stationary, sending out, however, his reconnoisances as far as Pulawa. On the 20th of February our main army was engaged with the enemy the whole day upon the same position as on the preceding. This repetition of his attack, without a change of plan or position, was a great weakness in the enemy. On that day, feeling sensibly the loss of a part of the great forest opposite Kawenzyn, as well as that of the small forest of elders, the enemy commenced his attack upon those points. Some twenty battalions were incessantly pushed forward to the attack, against which eight battalions on our part kept an effectual stand for several hours. This day, although uninteresting and indecisive in manoeuvres, was bloody. No important blow was attempted by us, but every attack of the enemy was met with a vigorous and sanguinary repulse. It was a day of glory for the 4th regiment--the day on which that celebrated regiment, though already distinguished, began to take its high place in our reports; and on which it fought with a degree of valor that could never have been surpassed. Without even waiting for orders, this brave regiment was seen constantly pushing itself towards the points of the greatest danger; and its companies were often fighting singly in the very midst of the thickest masses of the enemy. By the unsuccessful and costly attacks of the enemy the whole day was occupied, and at its close, after the loss of thousands of men, he had not gained a foot of ground.
