Various events meanwhile concurred to postpone the execution of Bonaparte's project and so to prolong the watch of the British admiral. The Boulogne flotilla itself was not as forward as had been expected; but the drain made by it upon the French arsenals, for workmen and materials, was a greater cause of delay, by retarding the equipment of the ships meant to cover the crossing. In December only seven of the line were ready in Toulon. [132] In the spring of 1804, the first consul's attention was absorbed by the royalist plot, which led to the arrest of Pichegru and Moreau, to the seizure of the Duc d'Enghien on German soil and to his execution at Vincennes in March. This last event had diplomatic consequences, in the attitude taken by Russia and Prussia, which still farther engrossed him; and the invasion of Great Britain was thus by successive delays put off to the summer of 1804. On May 25, Napoleon, who had assumed the imperial title on the 18th of that month, writes to Latouche [133] that on the ocean side all was prepared, that the project was only postponed, not abandoned, and asks if he will be ready by July. July 2 he writes again, [134] anticipating his sailing from Toulon by the first of August, instructs him to pick up at Cadiz one French ship-of-the-line which had taken refuge there, thence to go to Rochefort, and finally to reach Boulogne, according to the first plan, by passing through the Channel; or, if necessary, by going north of the British islands. In all passages from port to port he was to keep far out to sea to avoid detection. "Let us," he adds, "be masters of the Strait for six hours and we shall be masters of the world." On the 2d of August, however, Napoleon postpones the invasion for some weeks, because some divisions of the flotilla had not yet joined; and on the 20th of that month Latouche Tréville died.

This loss was serious, as there was not among the surviving French admirals any who had shown himself fit for so important a task, except perhaps Bruix. He, being already definitely associated with the flotilla, could not well be displaced; and his health, moreover, was very bad, so that he also died the following March. Of two others who might possibly prove equal to high command, Rosily and Villeneuve, Napoleon, after some hesitation and with much mistrust, chose the latter. "All naval expeditions undertaken since I have been at the head of the government," said he, "have always failed, because the admirals see double, and have learned—where, I do not know—that war can be made without running risks." [135] From this simple and undeniable standpoint no choice more unfortunate than Villeneuve could have been made. Accomplished, brave, and skilful, he saw the defects of the French navy with a clearness which absolutely sapped his power to take risks. Although capable of the utmost self-devotion, he was unable to devote his command as the forlorn hope upon which might follow a great achievement.

Doubting Villeneuve's resolution, Napoleon now changed the details of his combination; giving to the Toulon fleet the inferior rôle of a diversion, instead of the great part of covering the flotilla at the chief centre of strategic action. The Brest fleet, during the life of Latouche Tréville, had been destined to tie Cornwallis to the French coast by the passive service of a mere demonstration. It was now given the principal part. Its admiral, Ganteaume, had in 1801 been blamed for not relieving Egypt; but Napoleon still felt for him the partiality of close personal association, and knew him to be an able officer. In the new plan, therefore, the Irish expedition passed definitively from a demonstration to a resolve. To it were assigned eighteen thousand troops under Marshal Augereau. Embarking them, Ganteaume should sail with a fleet of twenty ships-of-the-line, pass far out into the Atlantic to baffle pursuit, and then head for the north of Ireland as though coming from Newfoundland. Having landed the soldiers, for which only thirty-six hours were allowed, the fleet should sail for the straits of Dover, either by the English Channel or by the north of Scotland, according to the winds. Arriving near its destination two courses were open, the choice between which would again depend on the wind. Either the Grand Army at Boulogne would cross at once to England, or a corps of twenty-five thousand assembled in Holland under General Marmont, would sail under Ganteaume's convoy for Ireland. "With only eighteen thousand men in Ireland," wrote Napoleon, "we would run great risks; but whether they be increased to forty thousand, or I myself be in England and eighteen thousand in Ireland, the gain of the war will be ours." [136]

The Toulon and Rochefort squadrons were to favor these operations by a powerful diversion. They were to sail separately for the West Indies, the former numbering twelve of the line and the latter five. Upon reaching the Atlantic two of the Toulon ships were to be directed against St. Helena, which they were to seize and then cruise in its neighborhood for three months against British commerce. The rest of the division, carrying four thousand troops, was to retake Dutch Guiana and re-enforce San Domingo, [137] if possible. The Rochefort division, lately commanded by Villeneuve, but now by Missiessy, was to seize the islands Santa Lucia and Dominica, re-enforce Martinique and Guadaloupe and then join Villeneuve. Thus combined, all would return to Europe, appear before Ferrol, releasing five French ships which were there blockaded, and finally anchor at Rochefort. "Thus attacked simultaneously in Asia, Africa, and America," wrote Napoleon, "the English, long accustomed not to suffer from the war, will by these successive shocks to their commerce feel the evidence of their weakness. I think that the sailing of these twenty ships-of-the-line will oblige them to dispatch over thirty in pursuit." [138] Villeneuve was to sail by October 12, and Missiessy before November 1. The Irish expedition should await the departure of the others, but it was hoped might get away before November 23.

This second combination was more vast, more complicated and therefore much more difficult than the first. It is interesting chiefly as indicating the transition in the emperor's mind, from the comparatively simple scheme laid down for Latouche Tréville to the grandiose conception which ended in Trafalgar and claimed Villeneuve as its victim. The course of events, mightier than the wills of sovereigns, now intervened to change again Napoleon's purpose and restore to the Toulon fleet the central part in the great drama. In December, 1804, formal war broke out between Great Britain and Spain.

Spain since 1796 had been in defensive and offensive alliance with France. By the treaty of San Ildefonso, then signed, she had bound herself to furnish, upon the simple demand of the French government, fifteen ships-of-the-line to re-enforce the French navy, as well as a specified body of troops. Holland also had entered into a similar covenant "forever" against Great Britain. At the outbreak of hostilities, therefore, Bonaparte found on either flank a maritime state formally obliged to aid him, whatever its present wish. Holland, a small flat country near at hand, was easily dominated by his army. It was rich, had a valid government and energetic people; and its position admirably seconded his schemes against Great Britain. It therefore suited him to have the Batavian republic join in the war. Spain, on the contrary, being extensive and rugged, was with difficulty controlled by an armed force, as Napoleon afterwards learned to his cost. It was remote from the centre of his power and from the intended operations; while effective military support could not be had from its government, feeble to disorganization, nor from its people, indolent and jealous of foreigners. One thing only was left to Spain of her former greatness,—the silver poured into her treasury from her colonies.

Bonaparte therefore decided to allow the neutrality of Spain, and to relinquish the stipulated aid in kind, upon condition of receiving an equivalent in money. This he fixed at six million francs per month, or about fourteen million dollars annually. Spain protested earnestly against the amount, but the first consul was inexorable. He required also that all levies of troops should cease, any land forces sent into the provinces adjoining France, since September, 1801, should be withdrawn, and the Spanish navy reorganized. Further, he demanded that five French ships-of-the-line then in Ferrol, where they had taken refuge from the British navy in July, 1803, when returning from Haïti, should be by Spain repaired and got ready for sea. "Spain," said Bonaparte, "has three alternatives: 1, she may declare war against England; 2, she may pay the specified subsidy; 3, war will be declared by France against Spain." [139]

When war began, the British minister at Madrid was instructed to ask if Spain intended to furnish France the ships promised by the treaty. If the answer was yes, he was to express no opinion, but say that any excess over the stipulations would be regarded as a declaration of war. Later, when it became known that Spain had signed a convention [140] stipulating the payment of subsidies to France, the ministry took the ground that this was a just cause of war, whenever Great Britain chose so to consider it; though for the time she might pass it over. "You will explain distinctly," ran the ambassador's instructions, dated November 24, 1803, "that his Majesty can only be induced to abstain from immediate hostilities in consequence of such a measure, upon the consideration that it is a temporary expedient, ... and that his Majesty must be at liberty to consider a perseverance in the system of furnishing succors to France as, at any future period, when circumstances may render it necessary, a just cause of war." [141] "I am expressly enjoined to declare," wrote the British ambassador, in making this communication, "that such payments are a war subsidy, a succor the most efficacious, the best adapted to the wants and situation of the enemy, the most prejudicial to the interests of his Britannic Majesty's subjects, and the most dangerous to his dominions; in fine, more than equivalent to every other species of aggression." [142] Repeated inquiries failed to draw from the Spanish government any official statement of the terms of its bargain, either as to the amount of the subsidy, the period during which it should continue, or other conditions of the agreement. [143] Such communication the French ambassador positively over-ruled. [144]

Warning was therefore early given [145] that a condition essential to postponement of action by Great Britain was the suspension of all further arming in Spanish ports. This was repeated in the most formal terms, and as an ultimatum, a few weeks later, on the 18th of February, 1804. "I am ordered to declare to you that the system of forbearance on the part of England absolutely depends on the cessation of every naval armament, and I am expressly forbidden to prolong my residence here, if unfortunately this condition should be rejected." [146] It was alleged and was incontrovertibly true, that, while Spain was so evidently under Bonaparte's influence, armaments in her ports as effectively necessitated watching, and so as greatly added to Great Britain's burdens, as if war actually existed. [147] Another complaint was that prizes made by French privateers were, by process of law, condemned and sold in Spanish ports. [148] The same was doubtless allowed to Great Britain; but in the strict blockade of the ports of France the latter here derived a great benefit, while upon her enemy was simply imposed an additional burden in scouring all the Spanish coast, as though actually at war, in order to recapture inward-bound prizes. Once condemned, the prize goods found their way to the French ports by Spanish coasters. Independent of the difficulty of identifying the property, the small size of these neutral carriers made seizure inexpedient; for the costs of condemnation were greater than the value of the prize. [149] The Spanish government claimed that the condemnation and sale of prize goods in their ports was simply an act of authorized commerce, free from all hostility. [150] Americans who recall the cruises of the Alabama and her fellows will be disposed to think that, whatever the technical accuracy of the plea, neutrality benevolent to an enemy's cruisers constitutes a just cause of war, whenever policy so advises.

The relations between the two countries continued in this strained and critical condition during the greater part of 1804. Bonaparte insisted that the Spanish dockyards should repair the French ships in Ferrol and Cadiz,—which was indeed one of the conditions of the convention of October 19, 1803, concealed from Great Britain,—and should permit seamen to pass by land from one port of Spain to another, and from France through Spain, to complete their crews. He consented indeed that they should go in small bodies of thirty or forty, but the vigilance of the British officials could not be deceived. The relations between France and Spain at this time were not inaptly described in the letter of Napoleon to the king, announcing his assumption of the imperial dignity. He styled him therein "ally and confederate." In June, 1804, an aide-de-camp of the emperor visited Ferrol and Madrid, charged to ascertain the condition of the ships and demand their completion. [151] The British minister could obtain no explanation of this mission, which naturally aroused his attention. [152] Spain in truth was no longer a free agent. On the 3d of July, Napoleon ordered his Minister of Marine to send to Ferrol the men still needed to man the ships there; and on the 19th of the month [153] the British admiral Cochrane, then blockading the port, remonstrated with the governor of Galicia upon this procedure as hostile to Great Britain. On the 3d of September, and again on the 11th, Cochrane wrote to his government that Spanish ships in Ferrol were fitting for sea, that three first-rates were expected from Cadiz, and that no doubt remained that the French, Spanish, and Dutch ships in the port were to act together. He had consequently found necessary to concentrate his force. [154] Immediately upon receiving this information, the British ministry notified the Spanish government that orders had been sent to their admiral off Ferrol to prevent any Spanish ships of war from entering or leaving that port. The ambassador at Madrid was directed to require that the armaments should be discontinued, and placed upon the same footing as before the war. He was also to demand a clear explanation of the relations existing between France and Spain. Unless satisfactory replies were given, he was ordered to quit Madrid.
