Germany: OHL found and fund Tirpitz’s new Fatherland Party (he addresses first meeting in Berlin September 25; 1.25 million members by July 1918).
Russia: Russian Premier Kerensky orders the arrest several military and civilian leaders on charges of a counter-revolutionary plot (The Kornilov Affair). This was was an attempted military coup d'état by the then Commander-in-Chief of the Russian Army, General Lavr Kornilov, in August 1917 (O. S. calendar) against the Russian Provisional Government headed by Aleksander Kerensky and the Petrograd Soviet of Soldiers and Workers Deputies. The affair began with Kerensky requesting that Kornilov move forces loyal to the Provisional Government into Petrograd to counter the threat of the radical (and Soviet-controlled) Petrograd army garrison. Kornilov then marched on Petrograd intent on 'purging' the Provisional Government of revolutionary elements, possibly with the intention of establishing a military dictatorship. Kerensky then countered Kornilov by eventually arming the Bolshevik-influenced Soviets, with the result that Kornilov and his closest advisers were imprisoned, and the Bolsheviks permanently armed and empowered.
