It was Woodrow Wilson, a civilian, who advised, urged, and insisted that a mine barrage be laid across the North Sea to check German submarine activities at their source. Naval experts pronounced the plan impossible: it would take too long to lay the barrage, and, when laid, it would not hold. A great storm would sweep it away. But the President insisted that the thing could be done, and that nothing else could check the submarine devastation amounting by July, 1917, to 600,000 tons a month of destroyed shipping. The President's audacity and persistence prevailed, and it is not too much to say that his plan ended the submarine menace. It will be recalled that European newspapers carried a story of a farewell reception to Mr. Bonar Law, in which he paid his compliments to his chief, Mr. Lloyd George, saying, in substance, that he had seen Lloyd George discouraged only once. It was on the morning when the news came of the great German offensive in March, 1918. Mr. Lloyd George told Mr. Bonar Law that morning that only a vast increase in American reinforcements could save the Allies. A cable was immediately framed, asking Mr. Wilson to send the number of reinforcements necessary. Mr. Bonar Law stated in his speech that an affirmative answer was received from Mr. Wilson the same day. A prominent Englishman, discussing the President's work in connection with the war, while criticizing what he characterized as the President's ignorance of European conditions, said: "I feel ashamed to be criticizing President Wilson for anything when I remember his practical services in prosecuting the war. No other man in any country gave such firm and instant support to every measure for making operations effective. His decisions were fearless and prompt and he stood by them like a rock. In sending troops promptly and in sending plenty of them, in cooperating in the naval effort, in insisting on the unity of command under Foch, in backing the high command in the field, and in every other practical detail Mr. Wilson had big, clear conceptions and the courage to carry them out." Those who were critical of the President's conduct of the war forget the ringing statement that came from Lloyd George when the great offensive was on, when he said: "The race is now between Von Hindenburg and Wilson." And Wilson won. The most important speech made by the President during the war was delivered at the Metropolitan Opera House, New York City, on September 27, 1918, opening the campaign for the Fourth Liberty Loan.
