German troops were in Finland, the Baltic States, Poland, Belarus, Ukraine, much of Romania, the Crimea, and in a salient east of Ukraine extending east almost to the Volga and south into Georgia and Armenia. Hundreds of thousands of men were needed to hold and police these conquests. More Germans were in Macedonia and in Palestine, where the British were driving north; Falkenhayn was replaced by Otto Liman von Sanders, who had led the defense of Gallipoli. All Hindenburg required was that these fronts stand firm while the Germans won in the west, where now they outnumbered their opponents. He firmly believed that his opponents could be crushed by battlefield defeats regardless of their far superior resources.
