Articles and letters came to Arbois in that early September, bringing an echo of the sorrows of Paris. Pasteur was then reading the works of General Foy, wherein he found thoughts in accordance with his own, occasionally copying out such passages as the following: “Right and Might struggle for the world; Right, which constitutes and preserves Society; Might, which overcomes nations and bleeds them to death.”

General Foy fought for France during twenty-five years, and, writing in 1820, recalled with a patriotic shudder the horrors of foreign invasions. Long after peace was signed, by a chance meeting in a street in Paris, General Foy found himself face to face with Wellington. The sight was so odious to him that he spoke of this meeting in the Chambre with an accent of sorrowful humiliation which breathed the sadness of Waterloo over the whole assembly. Pasteur could well understand the long continued vibration of that suffering chord, he, who never afterwards could speak without a thrill of sorrow of that war which Germany, in defiance of humanity, was inexcusably pursuing.

It was the fourth time in less than a hundred years that a Prussian invasion overflowed into France. But instead of 42,000 Prussians, scattered in 1792 over the sacred soil of the Patrie—Pasteur pronounced the word with the faith and tenderness of a true son of France—there were now 518,000 men to fight 285,000 French.

The thought that they had been armed in secret for the conquest of neighbouring lands, the memory of France’s optimism until that diplomatic incident, invented so that France might stumble over it, and the inaction of Europe, inspired Pasteur with reflections which he confided to his pupil Raulin. “What folly, what blindness,” he wrote (September 17), “there are in the inertia of Austria, Russia, England! What ignorance in our army leaders of the respective forces of the two nations! We savants were indeed right when we deplored the poverty of the department of Public Instruction! The real cause of our misfortunes lies there. It is not with impunity—as it will one day be recognized, too late—that a great nation is allowed to lose its intellectual standard. But, as you say, if we rise again from those disasters, we shall again see our statesmen lose themselves in endless discussions on forms of government and abstract political questions instead of going to the root of the matter. We are paying the penalty of fifty years’ forgetfulness of science, of its conditions of development, of its immense influence on the destiny of a great people, and of all that might have assisted the diffusion of light.... I cannot go on, all this hurts me. I try to put away all such memories, and also the sight of our terrible distress, in which it seems that a desperate resistance is the only hope we have left. I wish that France may fight to her last man, to her last fortress. I wish that the war may be prolonged until the winter, when, the elements aiding us, all these Vandals may perish of cold and distress. Every one of my future works will bear on its title page the words: ‘Hatred to Prussia. Revenge! revenge!’”

There is a passage in the Psalms where the captives of Israel, led to Babylonian rivers, weep at the memory of Jerusalem. After swearing never to forget their country, they wish their enemies every misfortune, and hurl this last imprecation at Babylon: “Blessed shall he be that taketh thy children and throweth them against the stones.”[29] One of the most Christlike souls of our time, Henri Perreyve, speaking of Poland, of vanquished and oppressed nations, quoted this Psalm and exclaimed: “O Anger, man’s Anger, how difficult it is to drive thee out of man’s heart! and how irresistible are the flames kindled by the insolence of injustice!” Those flames were kindled in the soul of Pasteur, full as it was of human tenderness, and they burst out in that sobbing cry of despair.

On that 17th of September, the day before Paris was invested, Jules Favre made another attempt to obtain peace. He published an account of that interview which took place at the Château of Ferrières, near Meaux; this printed account reached every town in France, and was read with grief and anger.

Jules Favre had deluded himself into thinking that victorious Prussia would limit its demands to a war indemnity, probably a formidable one. But Bismarck, besides the indemnity, intended to take a portion of French soil, and claimed Strasburg first of all. “It is the key of the house; I must have it.” And with Strasburg he wanted the whole Department of the Haut-Rhin, that of the Bas-Rhin, Metz, and a part of the Department of Moselle. Jules Favre, characteristically French, exhausted his eloquence in putting sentiment into politics, spoke of European rights, of the right of the people to dispose of themselves, tried to bring out the fact that a brutal annexation was in direct opposition to the progress of civilization. “I know very well,” said Bismarck, “that they (meaning the Alsatians and Lorrainers) do not want us; they will give us a deal of trouble, but we must annex them.” In the event of a future war Prussia was to have the advantage. All this was said with an authoritative courtesy, an insolent tranquillity, through which contempt for men was visible, evidently the best means of governing them in Bismarck’s eyes. As Jules Favre was pleading the cause of heroic Strasburg, whose long resistance was the admiration of Paris, “Strasburg will now fall into our hands,” said Bismarck coldly; “it is but a question for engineers; therefore I request that the garrison should surrender as prisoners of war.”

Jules Favre “leapt in his grief”—the words are his—but King Wilhelm exacted this condition. Jules Favre, almost breaking down, turning away to hide the tears that welled into his eyes, ended the interview with these words: “It is an indefinite struggle between two nations who should go hand in hand.”

Traces of this patriotic anguish are to be found in one of Pasteur’s notebooks, as well as a circular addressed by Jules Favre to the diplomatic representatives in answer to certain points disputed by Bismarck. Pasteur admiringly took note of the following passage: “I know not what destinies Fate has in store for us. But I do feel most deeply that if I had to choose between the present situation of France and that of Prussia, I should decide for the former. Better far our sufferings, our perils, our sacrifices, than the cruel and inflexible ambition of our foe.”

“We must preserve hope until the end,” wrote Pasteur after reading the above, “say nothing to discourage each other, and wish ardently for a prolonged struggle. Let us think of hopeful things; Bazaine may save us.”... How many French hearts were sharing that hope at the very time when Bazaine was preparing to betray Metz, his troops and his flag!
