[Footnote 73: As we have been informed, Wilno was defended by five corps, consisting in all, of about 30,000 men, under generals Kuruta, Tolstoy, Saken, Malinowski, and Szyrman.] [Footnote 74: This Lithuanian force consisted of the regiment of the countess Plater, who accompanied them in the charge.] [Footnote 75: This valuable officer, colonel Valentin, unfortunately lost his life on the day after the battle of Wilno, while bathing in the Wiliia. The regrets of his brother officers were aggravated by their sense of the value of those wise counsels, the suggestion of which was the last act of his life. He had every quality of heart and intellect for the highest military station.] CHAPTER XXII. Operations of the main army.--Expedition under Jankowski.--General Chrzanowski having driven Rudiger from his position, crosses the Vistula, but returns to act in concert with general Jankowski against the enemy near Kock.--Details of general Jankowski's movement.--He remains inactive within sight of the fire of the corps with which he was to co-operate.--Other evidences of treason.--Generals Jankowski and Bukowski are arrested and ordered for trial.--View of the advantages that were sacrificed by this misconduct.--Discovery of a plot to liberate and arm the Russian prisoners at Warsaw, and to deliver the city to the enemy.--State of the public mind induced by these events. From these melancholy occurrences in Lithuania, let us turn to follow the operations of the grand army. On the 13th and 14th of June, a division of infantry, under the command of general Muhlberg, left Praga, and took the direction of the environs of Stanislawow and Jadow. In the latter place this division surprised a strong detachment of the enemy in camp, and took many prisoners. Thence they were instructed to follow the left bank of the Liwiec as far as the environs of Kaluszyn, and even to Zelechow, clearing each bank of the presence of the enemy. This division was then to join itself with the division of cavalry of general Jankowski, which on that day left for Kock. Those two divisions combined, were to endeavor to act upon the different corps of the enemy which were pressed by the corps of general Chrzanowski. The latter general had commenced the offensive on the 16th, and had driven the corps of general Rudiger from its position at Krasny-taw, and compelled it to retreat to Lublin, continually pursued by him. On the 23d, he took that town by storm. The enemy was obliged to evacuate it in disorder, leaving a great number killed, wounded, and prisoners, and to take the direction of Kock. The corps of Rudiger would have been inevitably destroyed, if another Russian corps of 15,000 strong had not marched to its aid.
