Russian commander in chief deprived the prince of Wirtemberg of his post, and his name was not heard of during the rest of the war. General Dwernicki, by his victories over this corps, had completely freed the department of Lublin from the presence of the enemy. On arriving at Lublin, he restored the authority of the National Government in that place, and the region about. He made the necessary arrangements for reinforcing his corps, and left for Krasny-taw, in the environs of Zamosc. While these successful operations of general Dwernicki, in the southern part of the kingdom, were in progress, and by this series of victories, he was approaching the frontiers of Wolhynia and Podolia, our arms were not less successful in the North. The brave colonel Valentin, with a small detachment of partizans, fought the enemy with success between Modlin and Pultusk. This detachment was thrown into that region, (acting, however, more particularly between the rivers Wkra and Orsyca,) in order to hold in check the operations of the enemy upon Plock. This detachment was to obtain succor, in case of necessity, from the garrisons of Modlin. It was especially destined to intercept the transports which were to come from Prussia upon the road to Mlara, for the relief of the Russian army. Colonel Valentin was occupying with his detachment the forest near the town of Nasielsk, when he was apprised that a small body of Russian troops, under the order of colonel Schindler, consisting of two regiments of cavalry, a battalion of infantry, and two pieces of cannon, had arrived on the 3d of March, at that town. This detachment had been sent to protect a transport which was to pass there. Colonel Valentin immediately formed a plan to attack it. During the night of the 3d and 4th of March, he approached the town, invested it, and ordered an attack, in which the detachment surprised the enemy, and forced him to quit the city, leaving his two pieces of artillery, and a number of prisoners. Colonel Valentin, thinking that the Russians might possibly return with a superior force, evacuated the city, and took his prisoners to Modlin, in order, by disembarrasing himself of them, to hasten his march and reach the environs of Pultusk, in time to intercept the transport. On the 5th, he took this transport, consisting of eighty vehicles loaded with various kinds of provision, together with twelve loads of equipage, &c, for the Russian generals, which he sent to Warsaw. The detachment of colonel Valentin continued to manoeuvre for a long while in those environs without any support.
