The patriots now proceeded to choose members of the provisional government. Prince Adam Czartoriski,[15] Radzivil,[16] Niemcewicz, and Lelewell were elected, and one of the old ministers, Lubecki, was retained to assist them. This arrangement was made public about noon, in order to tranquilize the people. The first step taken by the new government was to send deputies to the Grand Duke. They were instructed to demand whether he meant to depart peaceably, or to attack the city. Among the deputies were Lubecki and Lelewell. They found the Grand Duke encamped, with his army, in the fields of Mokotow. The deputies represented to Constantine the consequences that would result from an attack on the city, as well in regard to himself as to the nation. They informed him that the army had already joined the people, and proposed to him that he should depart unmolested, on a prescribed route. They promised that he should find every possible accommodation provided on that route, for himself and his troops. The Grand Duke demanded some time for reflection, and finally gave the deputies the following answer in writing. ART. I. The Grand Duke declares that it was never his intention to attack Warsaw. In case he should find himself under the necessity of so doing, he will give the authorities notice of his intention forty-eight hours before the attack. ART. II. The Grand Duke will entreat the Emperor to grant an amnesty for the past. ART. III. The Grand Duke declares that he has sent no orders to the Russian forces in Lithuania to pass the frontier of the kingdom. ART. IV. Prisoners will be exchanged. The deputies returned to Warsaw with this answer, at three o'clock. It was immediately published, but did not satisfy the people. They demanded to know the day and hour of the Grand Duke's departure. If he should refuse to obey, they declared that they would attack him. It was finally concluded to allow him two days for his necessary arrangements, and then to send a second deputation to insist on his instant departure.[17] The provisional government immediately set about restoring order to every department of the administration. The Bureau of Police was abolished, and a council of citizens was substituted in its place, under the direction of the aged and worthy Wengrzecki. This man had been president of Warsaw in the times of the grand duchy. He was compelled to leave this office, by certain persecutions, which he brought upon himself by not being sufficiently in the spirit of the Russian government. At the same time the national guard was established, and placed under the command of Count Lubinski. The guard began their service on the very same day. They mounted guard at the bank and the public treasury, and their patrols maintained order in all parts of the city. Their duties were performed with the utmost punctuality. All the shops were opened, and the city wore as peaceful an aspect as if there had been no army before it.
