By October 1919, the government was in the worst crisis of the Civil War: Denikin's troops approached Tula and Moscow from the south, and General Nikolay Yudenich's troops approached Petrograd from the west. Lenin decided that since it was more important to defend Moscow, Petrograd would have to be abandoned. Trotsky argued that Petrograd needed to be defended, at least in part to prevent Estonia and Finland from intervening. In a rare reversal, Trotsky was supported by Stalin and Zinoviev, and prevailed against Lenin in the Central Committee. He immediately went to Petrograd, whose leadership headed by Zinoviev he found demoralized, and organized its defense, sometimes personally stopping fleeing soldiers. By 22 October, the Red Army was on the offensive and in early November, Yudenich's troops were driven back to Estonia, where they were disarmed and interned. Trotsky was awarded the Order of the Red Banner for his actions in Petrograd.
