Igelström, who has rejected the plan and sees no need for the Russians to evacuate Warsaw, sends a corps under General Aleksandr Khrushchev to intercept Kościuszko and prevent him from approaching Warsaw.

He also orders increased surveillance of suspected supporters of the uprising, and imposed censorship all mail passing through Warsaw.

Igelström issues orders for the arrest of those he suspects of having any connection with the insurrection.

These include some of the more prominent political leaders, among them Generals Antoni Madaliński, Kazimierz Nestor Sapieha and Ignacy Działyński, King's Chamberlain Jan Walenty Węgierski, Marshal of the Sejm Stanisław Małachowski, Ignacy and Stanisław Potocki and Hugo Kołłątaj.

At the same time Russian forces start preparations to disarm the weak Polish garrison of Warsaw under General Stanisław Mokronowski by seizing the Warsaw Arsenal at Miodowa Street.

These orders only make the situation worse as they are leaked to the Poles.
