Pasteur, unable to serve his country except by his scientific researches, had the firm intention of continuing his work; but he was overwhelmed by the reverses which fell upon France, the idea of the bloodshed and of his invaded country oppressed him like a monomania.

“Do not stay in Paris,” Bertin said to him, echoed by Dr. Godélier. “You have no right to stay; you would be a useless mouth during the siege,” he added, almost cheerfully, earnestly desiring to see his friend out of harm’s way. Pasteur allowed himself to be persuaded, and started for Arbois on September 5, his heart aching for the sorrows of France.

Some notes and letters enable us to follow him there, in the daily detail of his life, amongst his books, his plans of future work, and now and then his outbursts of passionate grief. He tried to return to the books he loved, to feel over again the attraction of “all that is great and beautiful” to quote a favourite phrase. He read at that time Laplace’s Exposition du Système du Monde, and even copied out some fragments, general ideas, concurring with his own. The vision of a Galileo or a Newton rising through a series of inductions from “particular phenomena to others more far-reaching, and from those to the general laws of Nature,” on this earth, “itself so small a part of the solar system, and disappearing entirely in the immensity of the heavens, of which that system is but an unimportant corner,”—that vision enveloped Pasteur with the twofold feeling with which every man must be imbued: humility before the Great Mystery, and admiration for those who, raising a corner of the veil, prove that genius is divinely inspired. Such reading helped Pasteur through the sad time of anxious waiting, and he would repeat as in brighter days, “Laboremus.”

But sometimes, when he was sitting quietly with his wife and daughter, the trumpet call would sound, with which the Arbois crier preceded the proclaiming of news. Then everything was forgotten, the universal order of things of no account, and Pasteur’s anguished soul would concentrate itself on that imperceptible comer of the universe, France, his suffering country. He would go downstairs, mix with groups standing on the little bridge across the Cuisance, listen breathlessly to the official communication, and sadly go back to the room where the memories of his father only emphasized the painful contrast with the present time. In the most prominent place hung a large medallion of General Bonaparte, by the Franc-Comtois Huguenin, the habit of authority visible in the thin energetic face; then a larger effigy in bronzed plaster of Napoleon in profile, in a very simple uniform; by the mantelpiece a lithograph of the little King of Rome with his curly head; on the bookshelves, well within reach, books on the Great Epoch, read over and over again by the old soldier who had died in the humble room which still reflected some of the Imperial glory.

That glory, that legend had enveloped the childhood and youth of Pasteur, who, as he advanced in life, still preserved the same enthusiasm. His imagination pictured the Emperor, calm in the midst of battles, or reviewing his troops surrounded by an escort of field marshals, entering as a sovereign a capital not his own, then overwhelmed by numbers at Waterloo, and finally condemned to exile and inactivity, and dying in a long drawn agony. Glorious or lugubrious, those visions came back to him with poignant insistency in those days of September, 1870. What was Waterloo compared to Sedan! The departure for St. Helena had the grandeur of the end of an epic; it seemed almost enviable by the side of that last episode of the Second Empire, when Napoleon III, vanquished, spared by the death which he wooed, left Sedan by the Donchery road to enter the cottage where Bismarck was to inform him of the rendezvous given by the King of Prussia.

The Emperor had now but a shadow of power, having made the Empress Regent before he left Paris; it was therefore not the sword of France, but his own, that he was about to surrender. But he thought he might hope that the King of Prussia would show clemency to the French army and people, having many times declared that he made war on the Emperor and not on France.

“Can it be credited,” said Bismarck, speaking afterwards of that interview, “that he actually believed in our generosity!” The chancellor added, speaking of that somewhat protracted tête-à-tête, “I felt as I used to in my youth, when my partner in a cotillon was a girl to whom I did not quite know what to say, and whom nobody would fetch away for a turn!”

Napoleon III and the King of Prussia met in the Château of Bellevue, in the neighbourhood of Sedan, opposite a peninsula henceforth known by the sad name of “Camp of Misery.” The Emperor looked for the last time upon his 83,000 soldiers, disarmed, starving, waiting in the mud for the Prussian escort which was to convey them as prisoners far beyond the Rhine. Wilhelm did not even pronounce the word peace.

Jules Favre, taking possession on September 6 of the department of Foreign Affairs, recalled to the diplomatic agents the fall of the Empire and the words of the King of Prussia; then in an unaccustomed outburst of eloquence exclaimed: “Does the King of Prussia wish to continue an impious struggle which will be as fatal to him as to us? Does he wish to give to the world in the nineteenth century the cruel spectacle of two nations destroying each other and forgetful of human feelings, of reason and of science, heaping up ruin and death? Let him then assume the responsibility before the world and before posterity!” And then followed the celebrated phrase with which he has been violently and iniquitously reproached, and which expressed the unanimous sentiment of France: “We will not concede one inch of our territory nor a stone of our fortifications.”

Bismarck refused the interview Jules Favre asked of him (September 10), under the pretext that the new Government was irregular. The enemy was coming nearer and nearer to Paris. The French city was resolved to resist; thousands upon thousands of oxen were being corralled in the Bois de Boulogne; poor people from the suburbs were coming to take refuge in the city. On the Place de la Concorde, the statue which represents the city of Strasburg was covered with flowers and flags, and seemed to incarnate the idea of the Patrie itself.
