Heavy artillery duels are taking place in the region of Lake Dorn and in the Cerna River bend sector of the Macedonian front. The Germans evidently are preparing for the drive on Petrograd that has been expected in the Russian Baltic. Warships convoying transports are reported unofficially to have left Lubau, on the Baltic Sea, in an unknown destination, and, meanwhile, the Germans have renewed their activity on the northern part of the Russian front in the Baltic region. The British troops are fighting against the Turks six miles from Samara, on the right bank of the Tigris River, in Mesopotamia, having previously forced the Ottomans to evacuate Iztahilat. There has been a renewal of activity on the part of the Kurds against the Russians in Persia, but details are lacking as to the full extent of it.
