September 1917
British Major-General Alfred W. F. Knox's account of Russian General Kornilov's September 11 break with the Provisional Government followed by a published response
Cossack General Kornilov's supposed coup failed in September (Wikipedia Commons).
"I pledge you my word of honour as an officer and a soldier, and assure you once more that I, General Kornilov, son of a simple Cossack peasant, have by my whole life, and not by words only, shown my unfailing devotion to my country and to freedom, that I am opposed to all counter-revolutionary schemes only that the great Russian nation should continue independent."
"Comrade officers and soldiers! General Kornilov has rebelled against the Revolution and the Provisional Government. He wants to re-establish the old regime and to deprive the people of land and liberty. To forward his criminal object, he is ready to open the front to the Germans and to betray his country." (684)
