When Marshal Joffre visited the President in the spring of 1917, he was surprised, as he afterward said to Secretary Daniels, "to find that President Wilson had such a perfect mastery of the military situation. He had expected to meet a scholar, a statesman, and an idealist; he had not expected to meet a practical strategist fully conversant with all the military movements. "In answer to my question as to whether it would be feasible to send in advance of his army the general who was to command American troops in France, the President said at once that it could be arranged." The President and Marshal Joffre considered together a number of technical military problems. General Joffre gave the President his expert opinion as to what should be done in every instance and was surprised at the promptness with which in each case the President said: "It shall be done." A little incident at the White House at the luncheon given by the President to the members of the Democratic National Committee throws light upon the fighting qualities of the man. He asked Mr. Angus W. McLean, a warm and devoted friend from North Carolina, who was seated near him at the table, what the Scots down in North Carolina were saying about the war. Mr. McLean replied he could best answer the question by repeating what a friend of the President's father and an ardent admirer of the President had said about the President's attitude a few days previous. "I am afraid our President is not a true Scot, he doesn't show the fighting spirit characteristic of the Scots." The President promptly replied: "You tell our Scotch friend, McLean, that he does not accurately interpret the real Scottish character. If he did, he would understand my attitude. The Scotsman is slow to begin to fight but when once he begins he never knows when to quit." Two capital policies which contributed enormously to the winning of the war received their impulse from Woodrow Wilson—the unification of command of the Allied armies on the western front and the attack of submarines at their base in the North Sea. On November 18, 1918, Colonel House let it be known in London that he had received a cable from President Wilson stating emphatically that the United States Government considered unity of plan and control between the Allies and the United States to be essential in order to win the war and achieve a just and lasting peace.
