Meantime, Zola had tendered the resignation of his commission, and Marshal Soult, the Minister of War, who had been informed of the whole affair, objected that he ought not to have been set at liberty while this was still under consideration. Rovigo then wrote to the Minister justifying his own action;[10] and, in the result, after reference to the King in person, Zola's resignation was accepted.

Such are those facts of the case which seem to be well authenticated. It is known that several documents have disappeared from one of the Zola dossiers at the French Ministry of War, and that at least one letter attributed to Colonel Combe, who commanded the Foreign Legion in Zola's time, was forged; while another, couched in the strangest and wildest language, was doctored if not entirely invented. In such circumstances it is impossible to ascertain the whole truth concerning the affair, but the lenient view taken of it by the Duke of Rovigo, the life of high rectitude and able work which Zola led in after as in earlier years, the favour subsequently shown him by King Louis Philippe, to whom his case had been submitted, his later correspondence with Marshal Soult, to whom every particular was also known,—all tend to show that whatever may have been the exact nature of his delinquency, it was far less grave than his son's enemies wished one to imagine.

It is even possible that the documents which have disappeared from his dossier would have shown that he ended by completely justifying himself. Indeed, those documents may have been abstracted for the express purpose of leaving suspicion on his memory. On the other hand, there may have been some imprudence on his part, some neglect or infringement of the cast-iron military regulations; and, as Émile Zola himself has admitted, if it be true that his father became infatuated with Madame Fischer, he may for a moment have lost his head—particularly, one may add, at the thought of her approaching departure from Algiers. None can say how it really happened that the Fischers had some of Zola's money in their possession. Had it been coaxed, or extorted, or, indeed, perhaps stolen from him?[11] In such a case many suppositions are allowable. Even if Zola absconded from his regiment in a moment of madness, it does not necessarily follow that he intended to flee with the woman; in fact, his subsequent behaviour suggests other conclusions. Moreover, the assertions respecting the amount of the deficit in Zola's accounts are contradictory; and when it is observed that he can only have been charged temporarily with the wardrobe department of the Foreign Legion, in the place, it would seem, of a certain Lieutenant Ridoux,[12] the question even arises how far he himself was really responsible for the deficit. In any case, he speedily discharged his liability.

On quitting the service, if there had been anything particularly reprehensible in Zola's conduct, any reason why he should have shunned all who knew the particulars of his case, he would scarcely have established himself at Marseilles, the chief port by which France communicated with Algeria, one whose intercourse with the new colony was continuous. Yet that is what he did. He is found practising the profession of a civil engineer at Marseilles, residing in the Rue de l'Arbre till 1835, then on the Cannebière till 1838, and employing three draughtsmen and two pupils. He takes part in all sorts of enterprises, a scheme to improve the lighting of the city streets, another to increase its supply of fresh water, and a third to develop its port, in which last affair he proposed the construction of new maritime docks. He first turned his attention to that matter in 1834, and it gave him occupation for over four years, during which he busied himself with surveying and sounding work, drew up fourteen explanatory memoirs, prepared innumerable plans, journeyed four or five times to Paris, obtained private audiences of the King and the Prince de Joinville, held converse with statesmen and members of parliament, disbursed in expenses of divers kinds a hundred thousand francs—partly earned and partly inherited from his mother, who died in or about 1836—and carried on, meantime, an incessant newspaper campaign in support of his ideas.

But Marseilles preferred to construct the present Port de la Joliette, which has proved neither so safe nor so commodious an anchorage as was then anticipated, in such wise that more than once, of recent years, there has been talk of reverting to the skilful but contemned plans of François Zola. The latter was born before his time. In his various engineering enterprises, he constantly showed himself to be in advance of his age,—such as it was in France,—full of faith in science, gifted with remarkable foresight as to possible developments, and possessed of an energy which no rebuff could overcome. In 1831 his schemes for the fortification of Paris had been shelved; but directly that question was publicly revived by the French government (1839-1840), François Zola, undismayed by the failure of his long efforts at Marseilles, again did battle for his ideas. It is a curious circumstance, established by his writings and supplying strong proof of his foresight, that he was opposed to the construction of a rampart round the city, and advocated a system of detached forts. Long years afterwards, the Franco-German War of 1870 demonstrated the general accuracy of his views; the rampart, raised contrary to his advice, then proved absolutely useless, and is now being removed, in part at all events; while the advanced forts of the time, though their system was imperfect, alone rendered efficient service against the besiegers. But it is remarkable to find that of recent years, in adding to the forts which did duty during the German investment, in erecting others in advance of them so as to enclose a larger stretch of country, whence the city might derive supplies of food in time of siege, the French military authorities have followed in all noteworthy respects the line traced by François Zola, first in 1831, and secondly in 1840!

Thus time brings round its revenges. François Zola was a gifted and able man, and well might a son be proud of having such a father. How proud Émile Zola was to have sprung from one who showed such practical and far-seeing genius, how he vindicated his memory, and smote his traducers, all may read in the little volume entitled "Truth on the March."

But before François Zola made fresh efforts in the matter of fortifying Paris, he had quitted Marseilles for Aix, the old capital of Provence, having observed in the course of some visits how greatly that ancient city and some of the surrounding country suffered from a lack of water. The idea of damming certain gorges, forming huge reservoirs into which the mountain torrents might fall, and bringing the water to Aix by a canal, occurred to him, and he had already studied the matter for some months, when, in September, 1838, the chief local journal, "Le Mémorial d'Aix," gave publicity to his views. A preliminary agreement with the Municipal Council followed in December, and from that moment, what with this canal scheme, the Marseilles project, and the plans for fortifying Paris, Zola had his hands full. He was frequently compelled to visit the capital, and on one such occasion he fell in love and married.

This occurred early in 1839. François Zola, who is described as being a genuine Italian in appearance, dark, with a very expressive face, a delicately curved mouth, a well-shaped nose, and piercing eyes, was then three and forty, while his bride was in her twentieth year, simple, gentle, and very pretty. Their first meeting recalled that of Faust and Marguerite. He perceived her as she was leaving church, fell in love with her on the spot, sought her home and her parents in the Rue de Cléry, and wooed her with all the ardour of his Italian temperament. Her name was Françoise Émilie Aubert. Born in 1819, under the shadow of the tower of Philip Augustus, in the little town of Dourdan,[13] between the forest of that name and the great grain-producing plain of La Beauce—where Émile Zola laid the scene of his novel "La Terre"—she was of modest condition, her father having retired from business as a tradesman at Dourdan, and made his home in Paris, where he lived on a small income. But François Zola was no dowry hunter. He loved Émilie Aubert, and that sufficed. Her parents consenting to the match, everything was settled in a few weeks, the marriage taking place at the town hall of the First Arrondissement of Paris, on March 16, 1839.
