On the 28th of June, general Skrzynecki received information of a conspiracy which had for its object the delivering up of Warsaw into the hands of the enemy, by liberating and arming the Russian prisoners. Several generals, of whom distrust had been felt, and who had been deprived of their commands when the revolution broke out, having been known as the vile instruments of the former government, were at the bottom of this plot. Of this painful intelligence, general Skrzynecki immediately apprized the National Government, who, relying on his report, caused to be arrested general Hurtig, former commander of the fortress of Zamosc, and a base instrument of Constantine, general Salacki, colonel Slupecki, the Russian chamberlain Fenshawe, a Mr Lessel, and a Russian lady, named Bazanow. Generals Jankowski and Bukowski were also implicated in the conspiracy. This band of traitors intended to get possession of the arsenal, to arm the Russian prisoners, and to destroy the bridges; (in order to cut off all communication with the army, which was then on the right bank of the Vistula;) and the Russian army, advertised of this movement, was then to pass to the left bank of the Vistula, at Plock or Dobzyn, and take possession of Warsaw. Those traitors succeeded in setting at large a great number of Russian prisoners at Czenstochowa. What a terror must poor Poland have been to the Russian cabinet, which did not find it enough to have deluged her with their immense forces, and to have engaged all the neighboring cabinets to aid them against her, but must go farther, and, by the employment of such vile means, attempt to kindle hostilities in her interior, and to subject her at the same time to a civil and an external war! They had good cause for these desperate attempts. From the earliest stage of the conflict, they had seen that the Poles, nerved by the consciousness of the justice of their cause, were capable of crushing the force which they had sent to execute the will of the despot. Unable to meet us in the open field, they must invent some new method, no matter how base, to accomplish their end. It was through the instrumentality of their intrigues that the dictatorship was prolonged. It was by such intrigues, that the apple of discord was thrown into our national congress, and even into the ranks of that handful of brave men who had sworn to sacrifice themselves in the cause of their country. They employed their vile accomplices to betray us, and they succeeded.
