Sir Douglas Haig’s battle, which ended on the 10th October, may be considered the determining action in the campaign, and it has been described by Foch as "a classic example of military art." It had no defect either of plan or of execution. The enemy was fairly and clearly defeated in a field action. Foch had played on the whole front a crescendo of deadly music, and the enemy’s strategic position was now so desperate that no local stand could save him. There was talk at the time of a German retreat to the Meuse. but it was an idle dream. Long before her broken divisions could reach that river Germany would be upon her knees. *PART III.* *THE "SIDE SHOWS."* *CHAPTER XVI.* *THE LANDING AT GALLIPOLI.* Early in 1915 it seemed to the British Government that, since there were no longer any flanks to be turned on the Western front, the lines in France and Flanders were settling down to a siege and a war of positions. They therefore looked elsewhere for some more promising area of battle, since, if the front door of a fortress is barred, there may be an entrance by a back door. The place which promised best was the narrow straits called the Dardanelles, which led from the Ægean into the Sea of Marmora, and so to Constantinople. There full use could be made of the British fleet. The capture of the Straits would involve the fall of the capital, and this might drive Turkey out of the war. Success there would bring over to our side the hesitating Balkan neutral states. It would open the road for Russia to import munitions of war, and to export her accumulated supplies of wheat. Lastly, Russia was being hard pressed, and had appealed to the Western Allies for aid, and her request could not be refused. Accordingly, it was decided to make an attempt upon the Dardanelles. The first effort was made by ships alone. But the Turks had powerful forts on both sides of the straits which could not be destroyed by naval guns. It was clear that the Dardanelles could not be opened until the Gallipoli Peninsula on the north side was captured. Unfortunately, the naval attack had forewarned the enemy, and he had enormously strengthened his position on the Gallipoli heights.
