On the fifteenth of December 1860, subscribers crowded the counting-houses of the Caisse Mirès to receive the first bonds of an Ottoman loan. Only the day before, the establishment had announced its proposal to redeem fifty million francs of its share capital. Throughout Paris, the intelligence appeared to confirm the unbounded prosperity of the house. Then a murmur ran through the assembled ranks: magistrates were on the premises, the ledgers had been placed under seal, and Jules Mirès was the subject of a judicial inquiry. Within hours, the unhesitating confidence that had buoyed the operations of the Caisse dissolved into acute alarm.
The chapter in the Pitaval, published in German in 1871, recounts this ruin as the history of a financier who mistook the industrial surge of the age for the mere fuel of unbridled speculation. Its author combines narrative exposition, transcripts of the debates, and moral commentary—the latter tainted at times by antisemitic prejudice. Here, such polemical assertions are kept strictly to their proper sphere: that of a nineteenth-century compiler, never that of legal evidence. The indictments, the successive judicial decrees, and the declarations of Mirès himself are scrupulously distinguished at every juncture.
A Man of the Press and of Credit
Jules Mirès was born in Bordeaux in 1809. The chronicle traces his trajectory from humble clerkships and modest commercial ventures to the Paris Bourse, which he began to frequent in 1844. He floated provisional scrip, allied himself with daily newspapers, and learned the art of lending financial undertakings the dazzling public visibility that captivates subscribers. In concert with Moïse Millaud, he acquired the Journal des chemins de fer; subsequently, he gained a controlling voice in Le Pays and Le Constitutionnel. The Pitaval dwells heavily upon the sway of financial publicity in these enterprises, though its insinuations regarding the banker’s origins must be ascribed to editorial bias rather than to the documented history of his transactions.
His establishment assumed the style of the Caisse Générale des Chemins de Fer. From 1850 onward, it amassed capital, managed investments, and launched vast industrial enterprises. It acquired coal mines near Marseilles, blast furnaces, municipal gasworks, reclaimed coastal lands, and railroad concessions. Foreign ventures further extended this scale: Italian railways, the line from Pamplona to Saragossa, a Spanish loan, and ultimately the Ottoman loan. The chronicle depicts an apparatus wherein the harvesting of capital and its public trumpetings advanced far more swiftly than the actual earthworks.
The figures governing the Roman railway project demonstrate the breadth of this ambition. To lay down some six hundred kilometres of track, the Caisse projected a capital of 175 million francs. The public subscription drew applications vastly exceeding the 170,000 shares available. Mirès allocated portions of these to his own firm, to his associates, and to the supervisory council; the public secured only a fraction. He then repurchased shares in the open market above par—an operation which the Pitaval estimates at more than two million francs. When the market turned, share prices collapsed, the influx of subscriptions dried up, and the enterprise was left to conjure funds precisely when its construction yards and legal engagements demanded immediate disbursements.
The narrative proceeds to expose the handling of securities deposited in trust or pledged as collateral. According to the prosecution, Mirès and his associate Solar alienated these assets without lawful authority, all the while permitting their clients to believe that the scrip remained safely in the vaults of the Caisse. Printed circulars announced formal liquidations and subsequent repurchases; the accounts rendered to depositors rarely reflected the actual sales. The dossier, therefore, did not merely encompass hazardous enterprises that had miscarried; it questioned whether the directors had disposed of property entrusted to the house as though it were their own.
Operations Under Judicial Scrutiny
The conflict broke into the open when the Baron de Pontalba, a member of the supervisory council, demanded 1.7 million francs under the heads of commissions and profits. He charged Mirès and Solar with embezzlement, the falsification of books, and the systematic deception of their clientele. Following an initial denunciation, he lodged a formal complaint with the Imperial Prosecutor on the second of December 1860. An inquiry was instituted; the ledgers were impounded, and Mirès was subjected to interrogation. He denied every imputation, invoked his past services to the nation, and denounced the proceeding as an extortionate maneuver intended to break his resolve.
Mirès concluded a financial settlement with Pontalba, but the payment of a sum exceeding one million francs only heightened the suspicions of the depositors. Meanwhile, the Caisse continued to operate. The chronicle affirms that it was already gravely undermined by tied-up capital, market losses, and accumulated obligations. On the seventeenth of February 1861, Mirès was arrested and conveyed to the prison of Mazas. A few weeks later, the Tribunal of Commerce pronounced the dissolution of the company and appointed official liquidators to wind up its affairs.
Forensic accountancy formed the backbone of the indictment. The report of the court-appointed experts, drafted by Monginot, drew up an inventory of alienated securities, profits credited to the balance sheet before they had been realized, and dividends calculated upon fraudulent valuations. The prosecution retained several counts: the unauthorized sale of securities entrusted to the Caisse, the withdrawal of shares against mere informal receipts, the issuance of provisional certificates in lieu of promised debentures, and the distribution of dividends which the experts branded as entirely fictitious. Mirès vigorously contested their methods and published his own defense, À mes juges, ma vie et mes affaires. He maintained that the sales had met the legitimate exigencies of the firm and that public securities were fungible goods, fully replaceable by other assets of the same denomination.
At the hearings of June and July 1861, clerks, depositors, and accounting experts were examined. Several clients testified that they had learned of the sale of their holdings only long after the event. Some were compelled to make repeated demands to recover their property; others found themselves presented with debit balances following forced sales calculated at entirely arbitrary prices. A former employee explained that he had discovered a private internal ledger recording sales that were carefully excised from the statements rendered to clients. The managers answered that the house possessed the legal right to employ deposited scrip to finance its ongoing operations, and that the depositors had subsequently been indemnified.
The testimony of the cashier, Roget, proved fatal regarding the shares withdrawn from the vaults. He stated that he had surrendered the scrip to Mirès and Solar against handwritten vouchers, without regular entry in the daybooks. He confirmed, moreover, that certain parcels of stock were still presented as physically present in the abstracts laid before the supervisory council. Mirès objected that he had duly returned the instruments and that the expert’s calculations took no account of these subsequent deliveries. The controversy was no mere abstraction: it turned upon the exact hour of withdrawal, the price of sale, the price of repurchase, and the precise sums carried to the credit of the company or to the private accounts of its managers.
Two Contradictory Decrees
The public prosecutor portrayed these transactions as an intricate chain wherein journalism, deceptive balance sheets, and ostensibly available scrip maintained a credit that the ledgers could not warrant. The defense countered that great commercial houses were obliged to keep their assets in circulation, that the financial panic of 1857 and foreign wars had convulsed the market, and that Mirès had harboured no intention to enrich his partners at the expense of his clients. Throughout the trial, Mirès intervened incessantly, disputed the competence of the experts, and demanded an independent counter-inquiry. The tribunal rejected his plea.
On the tenth of July 1861, the Paris Correctional Tribunal found Mirès and Solar guilty of multiple counts of swindling and breach of trust, sentencing each to five years’ imprisonment and a fine of 3,000 francs. It acquitted Mirès of the charge relating to the profits of the Spanish railway. Mirès and Solar were declared civilly liable alongside Count Siméon; the remaining members of the supervisory council were acquitted. This initial sentence was not, however, the final word: the condemned men lodged an immediate appeal.
The appellate court initially confirmed the substance of the convictions. Yet the steadfast refusal to order a fresh accounting examination proved decisive. The chronicle records that the Court of Cassation quashed the appellate decree for procedural irregularity and remitted the cause to another tribunal. It then portrays the assizes at Douai, where Mirès stood once more at the bar, reiterating his demand for an independent audit. The chronology of the dates printed in the German compilation is disordered on this head, placing a decree of cassation after the remand trial itself. The present chronicle consequently maintains the natural sequence of the judicial stages without assigning an arbitrary date to this cassation.
At Douai, on the twenty-first of April 1862, the court again declined to order an accounting inquiry, but proceeded to acquit Mirès. It held that the securities deposited with the Caisse were fungible in law, that the clients were entitled only to equivalent restitution, and that the contested transactions did not constitute the criminal offenses retained by the magistrates of Paris. This was an absolute acquittal, which brought an end to the personal prosecution detailed in the chronicle; Mirès was not returned to prison upon these charges.
The Procureur Général subsequently brought the matter before the Court of Cassation solely in the interest of the law. This procedural recourse permits the supreme bench to correct an erroneous construction of jurisprudence without reopening the indictment to the prejudice of an acquitted defendant. The compilation notes that the Court of Cassation deemed the doctrine pronounced at Douai to be fundamentally flawed, particularly regarding the legal nature of deposits, entrusted securities, and substituted certificates. Yet this doctrinal correction in no way altered the personal standing of Mirès, who retained the full benefit of his acquittal. The compiler vehemently denounces the Douai verdict; that indignation remains his own. The cardinal procedural reality remains that this ultimate review left the liberty of the accused untouched.
In December 1860, the subscribers had assembled to claim debentures that were meant to attest to the inexhaustible wealth of the Caisse. The judicial inquest laid bare ledgers, contracts, and instruments of debt whose legal import the courts read in opposite fashions. Paris convicted; Douai acquitted; the supreme court corrected the doctrine without disturbing the acquittal. As for the Caisse itself, it stood dissolved and broken. The promised millions had vanished into a bitter, contested reckoning between disillusioned depositors, clamorous creditors, and the men who had governed the house.
