When Bismarck announced to the Prussian Reichstag that war had been declared, he was interrupted by an outburst of long and enthusiastic cheering. He said, briefly, that he had no papers to lay before them, because the single official document received from the French Government was the declaration of war; and the only motive for hostilities he understood to be his own circular _telegramme de journal_ addressed to Prussian envoys abroad and to other friendly Powers for the purpose of explaining what had occurred. This, he observed, was not at all an official document. He added that a demand for a letter of excuses had been made through Werther to the king; and the real origin of the war he alleged to be the hatred and jealousy with which the independence and prosperity of Germany were regarded in France. Upon this adroit but incomplete exposition of causes and circumstances M. Ollivier comments with intelligible severity, laying stress on the fact that afterwards Bismarck threw off his disguise, and openly took to himself the credit of having deliberately contrived to bring on the war at his own time. In fact, the later German historians have confirmed this statement by their critical examination of the records and other evidence; though instead of concluding that his conduct was immoral they unite, according to M. Ollivier, in applauding his political genius. Almost the whole story of the connected machinations by which France was led step by step into war have since been disclosed, and the only part which is still unrevealed relates to the original devices by which Bismarck and Marshal Prim concerted the preliminaries to the offer of the Spanish throne to Leopold.[52]
