Therefore am I right, when I call the existing combat between France and Germany a Duel. I beg you to believe that I do this with no idle purpose of illustration or criticism, but because I would prepare the way for a proper comprehension of the remedy to be applied. How can this terrible controversy be adjusted? I see no practical method, which shall reconcile the sensibilities of France with the guaranties due to Germany, short of a radical change in the War System itself. That Security for the Future which Germany may justly exact can be obtained in no way so well as by the disarmament of France, to be followed naturally by the disarmament of other nations, and the substitution of some peaceful tribunal for the existing Trial by Battle. Any dismemberment, or curtailment of territory, will be poor and inadequate; for it will leave behind a perpetual sting. Something better must be done. SUDDENNESS OF THIS WAR. Never in history has so great a calamity descended so suddenly upon the Human Family, unless we except the earthquake toppling down cities and submersing a whole coast in a single night. But how small all that has ensued from any such convulsion, compared with the desolation and destruction already produced by this war! From the first murmur to the outbreak was a brief moment of time, as between the flash of lightning and the bursting of the thunder. At the beginning of July there was peace without suspicion of interruption. The Legislative Body had just discussed a proposition for the reduction of the annual Army Contingent. At Berlin the Parliament was not in session. Count Bismarck was at his country home in Pomerania, the King enjoying himself at Ems. How sudden and unexpected the change will appear from an illustrative circumstance. M. Prevost-Paradol, of rare talent and unhappy destiny, newly appointed Minister to the United States, embarked at Havre on the 1st of July, and reached Washington on the morning of the 14th of July. He assured me that when he left France there was no talk or thought of war. During his brief summer voyage the whole startling event had begun and culminated. Prince Leopold of Hohenzollern-Sigmaringen being invited to become candidate for the throne of Spain, France promptly sent her defiance to Prussia, followed a few days later by formal Declaration of War. The Minister was oppressed by the grave tidings coming upon him so unprepared, and sought relief in self- slaughter, being the first victim of the war. Everything moved with a rapidity borrowed from the new forces supplied by human invention, and the Gates of War swung wide open. CHALLENGE TO PRUSSIA.
