The corps of general Dwernicki was at Pulawy. The plan of operations which had been assigned to him, and which, indeed, he had already put in execution, was to transfer the seat of hostilities to the right bank of the Vistula, to hang over and harass the left wing of the enemy, to relieve the palatinate of Lublin from his presence, and, in case of danger, to fall back to the fortress of Zamosc, and from that point to act on the neighboring region, according as circumstances might indicate. Colonel Valentin was in the environs of Pultusk, with his small corps of partizans. In concert with the garrison of Modlin, he was to act on the right wing of the enemy, and hold in check all his manoeuvres upon Plock. This concave line of operations, of which the extremities were at Zamosc and Modlin, and the centre at Warsaw and Praga, was strengthened by the Vistula, which, although frozen, would not allow of a passage by the enemy in large bodies, or of the construction of a bridge, as the ice of the river was momentarily expected to break up. The position of the Russian army was as follows. The right wing was at Nowy-dwor, opposite to Modlin. At Jablonna, which is situated half way from Praga to Nowy-dwor, was placed a strong detachment. At Praga were two divisions, one of infantry, and the other of cavalry, with twelve pieces of cannon, under the command of general Giesmar. The greater body of the Russian forces was between Wawr and Milosna; and with them was the head-quarters of Diebitsch and Constantine. Their left wing occupied Karczew, and their patrols extended themselves along the right bank of the river, as far as Macieowice. FOOTNOTES:
