The year 1870, in which I returned home, was one of marked and decisive influence upon history, and in a way a turning-point in my own obscure career. As in February I witnessed the splendors of the papal city under its old regime, so in April and May I saw imperial Paris brilliant under the emperor. In the one case as in the other I was unconscious of the approaching _debacle_; a blindness I presume shared by most contemporaries. Whatever the wiser and more far-seeing might have prophesied as to the general ultimate issues, few or none could then have foretold the particular occasion which so soon afterwards opened the floodgates. As the old passed, with the downfall of the French Empire and of the temporal kingdom, there arose a new; not merely the German Empire and the unity of Italy, crowned by the possession of its historic capital, but, unrecognized for the moment, then came in that reign of organized and disciplined force, the full effect and function of which in the future men still only dimly discern. The successive rapid overthrows of the Austrian and French empires by military efficiency and skill; the beating in detail two separate foes who, united, might have been too strong for the victor; the consequent crumbling of the papal monarchy when French support was withdrawn, following closely on the Vatican Decree of Infallibility; these things produced an impression which was transmitted rapidly throughout the world of European civilization, till in the Farther East it reached Japan. Into the current thus established the petty stream of my own fortunes was drawn, little anticipated by myself. To it was due my special call; for by it was created the predisposition to recognize the momentous bearing of maritime force upon the course of history, which insured me a hearing when the fulness of my time was come.
