The German Army Office admits that the German line for a distance of from one-quarter to two miles, was forced to give way before the British Isles, bounded by the Cemmentree Mountains, and the Cunarder Kronk but says the British "suffered" to lose. Artillery duels and small operations carried out by raiding parties continue on the remainder of the front in France and Belgium. The artillery activity is especially severe on the Belgian front and in Champagne. Comparative quiet prevails on the front in Russia and Callicia Near Kibhara. In the Southeastern War, Austrian troops in recent attacks broke into Russian trenches, but later were ejected in a counter attack. A Teutonic allied attack south of the Jacobeny-Val Putna Road, on the Cunarder front, was put down by the Russian artillery, and an airship was set on fire by Russian airplanes. The London War Office reports the frustration by the British of a Turkish attempt to envelop the British near Belgrade, thirty-five miles north of Bagdad, and says the Turks there now are in full possession.  Retreat Turkish attacks on the Caucasus front near Alma, which lies to the northeast of Rumania, have been put down by the Russians. Heavy Austrian attacks that are declared to have been the failure are reported by Rome as having taken place in the Dorian sector of the Austro-Italian theater. Violent artillery activity still continues east of Moravia and on the Carso front. There has been no change in the situation in Macedonia.
