General Chrzanowski, apprized of the arrival of this reinforcement, quitted the pursuit, for a more favorable moment; and, to avoid an engagement with this combined force of the enemy, as well as to escort the prisoners, which he had taken at Lublin, to a place of safety, he repassed the Vistula, at Pulawy. He had scarce reached the opposite side of the river, when he received the intelligence that the division of general Jankowski, reinforced by a brigade of infantry, was approaching Kock, where was already the corps of general Rudiger, and whither the corps of general Keisarow, above mentioned, was hastening to join him. In order, therefore, to take between the two fires all the forces which might be collected at Kock, general Chrzanowski promptly repassed the river, reached the environs of Kock, and waited impatiently for the attack of general Jankowski, in the opposite direction; but Jankowski delayed his movement, and allowed the corps of Kiesarow to join Rudiger. The following are the details of this expedition, as they were related by an officer of the division of Muhlberg, and which exhibit satisfactory evidence of treason on the part of general Jankowski. 'The issue of this expedition, which could have had the most brilliant results, has filled us with grief and indignation. We were marching in the utmost haste upon Kock, with the hope of beating Rudiger. On our route, at Stoczek, for our misfortune, we were joined by the division of cavalry under general Jankowski, who then took the command. We ought to have passed the Wieprz, to meet Rudiger, and cut him off. Suddenly news was brought to us that the enemy had passed the Wieprz, at Lysobyki, with 6,000 infantry, sixteen squadrons of cavalry, and ten pieces of cannon. General Jankowski then called a council of war, at which the following plans were adopted. General Turno was to attack the enemy, in the direction of Sorokomla, and general Jankowski was to come to his support at the first sound of his cannon. The brigade of general Romarino (detached from the corps of general Chrzanowski, and destined to act as an independent corps) was to act upon the left wing, and general Bukowski, with a brigade of cavalry, upon the right wing of the enemy by Bialobrzegi. This plan, which in the conviction of all our officers would have exterminated the corps of general Rudiger, and the execution of which was reserved to general Jankowski, came to nothing.
