German diplomacy and staff work had not in all of the war gained a more important technical advantage for less cost in time, money, and troops, than it had in the fall of 1915 in the Balkans when they made the Bulgars to serve as they had the Turks, to secure their ends. At last the British withdrew from Gallipoli with such small losses that the evacuation of this position on an exposed coast is undoubtedly one of the most brilliant pieces of military maneuvering of its kind in all history. No credit is ever given for retreats. But this was a good deal more than a retreat. It was withdrawing from a beach in face of a well-armed enemy. The story of it--as yet unwritten--will some day bring a tribute to British military skill from professional soldiers, if not from the lay public. The Bulgarians decided not to invade Greece; the Greeks made no attack. Those who looked forward to the war being settled in the Balkans, and to Saloniki becoming another Port Arthur, had missed their calculations. But every gun and every man that the Allies had to maintain at Saloniki might be a gun and a man kept idle, when they might be needed elsewhere. The Germans having disposed of Serbia, had at the same time forced the further dissipation of English and French troops. That they could once more turn to the main theatre of the war and try to push back the siege wall in another direction. Meantime, Turkey had been doing their bidding in another quarter. The natural response of the British to any threat to their Indian Empire was to take the offensive, for this was one certain way to impress the Oriental mind. Having annexed Egypt and Cyprus and occupied the German colonies throughout the world, Britain now proceeded to the extension of her Asiatic domain. The threat of Mohammedan insurrection was met by an invasion of Mohammedan regions. Her expedition toward Bagdad, had it not been in the midst of the greatest war in all history, would perhaps have been the most spectacular and interesting of all the small campaigns in remote regions which have gradually extended British influence. It marched through Mesopotamia and the Garden of Eden. The Turks under German direction replied with an offensive which in turn put General Townshend's army in siege, requiring that it should have relief. The self-interest of each one of the parties to the war is evident, with the exception of Turkey. Why she ever entered in on the side of Germany, or on either side, is a puzzle. She was the one to lose in any event. German success meant German domination. German failure must mean that Russia would realize her ambition to take Constantinople, and the British must further strengthen their empire at her expense.
