A Great German philosopher said many years ago that history was the story of the struggle of the human race for freedom. Would the Huns conquer Europe and put back human liberty for hundreds of years? This was the question that was answered at the battle of the Marne in September, 1914, and the answer depended upon what General Foch was able to do with his army. It was necessary that he should attack, and General Joffre ordered him to do so. General Foch did not reply that he was having all he could do to hold his own and to prevent his army from being captured or destroyed, although this was really the situation. He sent back to his commanding general a message that will never be forgotten, one that was in keeping with the maxim he had always taught his students in the military school, that the best defense is an offense: "My left has been forced back; my right has been routed; I shall attack with my center." [Illustration: MARSHAL FERDINAND FOCH _Copyright by Underwood & Underwood, N.Y._] Foch is a man of medium height. His face is an especially striking one. He has the forehead of a thinker, with two deep folds between the eyebrows; he has deep-set eyes, a large nose, a strong mouth slightly hidden under a gray mustache, and a chin which shows decision and force. His whole face expresses great power of thought and will. Before the war, he was a professor of military history. He was accustomed to outline to the young officers in his class a clear statement of a military situation, and the orders which had been followed. He would then call upon his pupils to decide what difficulties would arise and what the results would be. In this way, they learned to discover for themselves the solutions of many kinds of military problems. Since Foch has been accustomed to this clear reasoning on all war problems, no military situation can surprise him. As a commander, he selects the goal to be reached, and the most skillful way of reaching it, and his men have confidence that he is right. This is what gives a commander the power to do things. Marshal Joffre realized General Foch's ability and quickly advanced him. After the First Battle of the Marne, it was necessary to appoint a commander for the French forces north of Paris, and it was very important to select one who had the initiative and the ability to check the German attempt to capture the Channel ports. The new commander must also be a man of great tact, for he would have to work with the British and the Belgians. General Foch was selected, and has proved to be the right man in the right place. The race for the Channel ports was an exciting one. Although the Germans lost, it seemed at times as if they would win, and be able to establish submarine bases within a very short distance of England. In fact, if they had captured Calais, they could have fired with their long-range guns across the Channel and have bombarded English coast towns, and perhaps London itself.
