Gorbatovskiy was replaced by General N.M. Kiselevskiy; 11th Army commander General V.N. Klembovskiy was briefly replaced by General D.V. Balanin, then by General A.E. Gutor; and General P.S.

The post of the Chief of the General Staff within the French War Ministry was revived, with General Petain being appointed to the post.

Attached was a note expressing “the aspiration of the whole people to bring the world war to a decisive victory” and reiterating Russia's faithfulness to their wartime agreements. Knowledge of these facts on 3-4 May, resulted in mass protests, many demanding that Milyukov resign. The protestors demanded peace without annexations or indemnities and the end of the war.
