ОглавлениеThe Mediterranean and Italy.—From the Evacuation of Toulon in 1793 to the British Withdrawal from that Sea, in 1796, and the Battle of Cape St. Vincent, February, 1797.—Austria Forced to Make Peace.
AFTER the evacuation of Toulon, on the 19th of December, 1793, Lord Hood had taken his fleet to Hyères Roads—an anchorage formed by the group of islands of the same name a few miles east of Toulon. There he remained during the greater part of January, revictualling his ships and considering what steps should next be taken to assure British interests in the Mediterranean.
It is essential to a fleet, as to an army, to have always near at hand depots of supplies, upon which it can depend to replace the consumption of the limited stores carried on board, and to which it can resort for refit. The way from the depots to the fleet, or the army, technically called the communications, should be such as can most easily be defended by the armed force itself, without impairing its liberty in movements necessary to obtain the objects of the war. In other words, this depot, or base, should be near the scene of operations and, when practicable, so situated that the fleet, while actively engaged, interposes directly or indirectly between it and the enemy. Nearness was doubly important in the days of sailing ships, whose movements depended upon the fickle element of the wind; for then a ship going in for refit not only took more time to perform the voyage, but also in returning made a heavier draft upon her resources, and consequently could remain a shorter period at the seat of war.
Toulon, while securely held, served as such a base; although, being exposed to overpowering attack from the land side, its situation called for excessive expenditure of effort. Toulon was, however, now lost, and the British were thrown back upon Gibraltar, at the very entrance of the Mediterranean, and nine hundred miles from the seat of hostilities, for a secure depot in which to land stores and a safe anchorage for transports and crippled ships-of-war.
Although the possession of a strong place, suited in itself for a base, may decide the character of operations projected, logically the necessary operations should first be determined, and the choice of the base be decided by them. In the Mediterranean, as elsewhere generally at this time, the policy of Great Britain was to control the sea for the protection of commerce, and to sustain on shore the continental powers in the war against France—chiefly by money, but also by naval co-operation when feasible. To support the land warfare, her diplomatic negotiations strove to unite, in the general military effort, as many as possible of the small independent states into which Italy was divided, to promote among them unity of action, and to foster the sense of security, in taking a decided step against France, which they could only derive from the presence among them of a strong power, such as Great Britain showed in her fleet. Neither their traditions nor the character of their rulers enabled them to combine strongly as equals; nor, as has before been said, was there any one state so predominant as to give a nucleus around which the others could gather. The only possible centre was Great Britain, present as a power in her fleet. Moreover, if unable, as she proved, to stir them up to positive, harmonious, concerted action, it was her interest to impose upon them a benevolent neutrality towards herself and her allies, and to deter them from inimical measures into which they might otherwise be impelled by the demands of the republic and their fear of the French army. Friendly ports along the whole coast were essential for the security of her shipping and the promotion of her commerce. Finally, it must be added that the character of the shore between Nice and Genoa, interposing between the French and Austrian armies, particularly favored direct naval co-operation. The Maritime Alps and the Apennines, coming down close to the sea, left but a single narrow, and yet long, line of communications along the beach, traversed by a very bad road, in many parts under fire from the sea. [105] This condition made the armies using that line chiefly dependent for supplies upon coasters, whose movements ships-of-war could harass and impede—though not, when sailing vessels, entirely stop.
Corsica, in its existing political conditions of revolt against France under the leadership of Paoli, appeared to offer the strategic situation which Hood was seeking. It was near and centrally placed with reference to the probable operations on shore; San Fiorenzo Bay, which became the chief anchorage for the fleet, being equidistant, about one hundred miles, from Nice and from Genoa. Leghorn also, one of the greatest depots of British trade in the Mediterranean and the seaport of Tuscany, over which Great Britain wished to enforce her influence, was but sixty miles from Cape Corso at the northern extremity of the island. All the trade with northern Italy had to pass close to Corsica, and was consequently exposed to capture if the seaports remained in French hands; especially as calms prevail around the island, facilitating the operations of row-galleys and neutralizing the powers of a sailing navy. Being an island, Corsica depended upon the control of the sea; and, though its size and rugged surface precluded conquest, there was believed to be a disposition to accept the protection of Great Britain as the only means of dispossessing the French troops, who still held the seaports of San Fiorenzo, Bastia, and Calvi.
Sir Gilbert Elliott, who had been the Civil Commissioner of Great Britain in Toulon during the last month of its occupation, left Hyères Bay early in January to confer with Paoli, who had proposed the annexation of the island to the British crown. His enthusiastic reception by the people and the assurances of the Corsican chieftain convinced him that the measure was sincerely desired; and in consequence of his representations, Hood, on the 24th of January, sailed from Hyères with his whole fleet for San Fiorenzo Bay. The weather proving very tempestuous, and the three-decked ships, of which there were several, being ill-fitted to contend with it, the admiral was forced to take them to Porto Ferrajo in Elba, and to send against San Fiorenzo a detachment only. This appeared off the place on the 7th of February; and after a series of combined operations, in which the navy bore a very conspicuous share on land, the French evacuated the town and works on the 19th of the month, retreating upon Bastia. The admiral then urged an attack upon Bastia; but the general thought he could not spare enough men. Nelson, who had been blockading there for some time, strongly represented the feasibility of the enterprise; and, after a sharp altercation between the two commanders-in-chief, Hood determined to undertake the siege with the navy and the troops who were serving on board as marines. The landing began on the 3d of April; but the place held out till the 21st of May, when it capitulated. Calvi was next taken in hand, the operations beginning on the 19th of June, and ending with its surrender on the 10th of August. The whole island was thus freed from the presence of French troops—a result due almost wholly to the navy, although the army bore a share in the operations at San Fiorenzo and Calvi. To the determination of Hood and the ardent representations of Nelson was due that Bastia was besieged at all; and, as thirty-five hundred regular troops then surrendered to an outside force of fourteen hundred seamen and marines, the opinion of Sir Gilbert Elliott that "the blockade of the port was the chief means of reducing it," can scarcely be disputed. At the siege of Calvi Nelson lost his right eye.
Between the siege of Bastia and that of Calvi, the General Assembly of Corsica met, and on the 19th of June, 1794, tendered the insular crown to the king of Great Britain. With the successful issue of the military operations, this political act consummated the possession of the island. But, to quote the words of Elliott, the claim to Corsica rested upon superior force, [106] and by that only could be asserted; and this superior force the British government failed to provide. The love of the people for Paoli, and the period of anxiety through which he and they had passed, caused the connection to be eagerly desired, and accepted with demonstrations of the warmest delight; but as security succeeded the sense of danger, the first-love between nations so radically distinct in temperament and institutions was followed by the symptoms attending ill-assorted unions. Still, with prompt action and strong garrisons, the benefit of the foreign occupation might have been manifest, dissatisfaction might have yielded to considerations of interest, and the island been retained. The British government acted slowly. Elliott had urged that authority should be sent him beforehand to take over the executive functions at once, as soon as the Act of Union passed; instead of which, Paoli was left for four months in his old position, and developed a jealousy of his destined successor not unprecedented in the heads of states. This feeling, which he held with Corsican intensity, communicated itself to his followers; and an inauspicious division of sentiment already existed when, in October, after an interval of four months, Elliott received his powers as viceroy. Paoli continued for a year longer to reside in Corsica, and up to the time of his departure was a cause of trouble to the viceroy, and so of strength to the partisans of France, who became numerous.
During the year 1794 the superior importance of the operations on the frontiers of Belgium and Germany, as well as in Spain, caused the French armies of Italy and the Alps to remain quiet, after some early successes which had placed in their hands the chief passes of the mountains and advanced their line on the coast as far as Vado, on the borders of Genoese territory. Early in 1795 a force of eighteen thousand men was detached to Toulon for the invasion of Corsica; but, although the French had in the port fifteen ships-of-the-line, they felt that neither the admiral nor the officers possessed the tactical skill necessary to handle the fleet in presence of an enemy of nearly equal force, if encumbered with a large body of transports. The case reproduced that of Conflans, when expected in 1759 to cover the French invasion of England. As a rule, in combined military and naval expeditions the fleet and the army should start together; but the tactical embarrassment of transports is indisputable. If the fleet cannot encounter the enemy successfully when not so hampered, it but encourages disaster to incur the meeting with them in company. Not improperly, in such a case of doubt, it was decided that the Toulon fleet should sail alone; and, accordingly, on the 2d of March, 1795, Admiral Martin put to sea with fifteen of the line, seven frigates, and five smaller vessels. Despite these respectable numbers, the efficiency of the force was poor. Out of twelve thousand officers and men on board the ships-of-the-line, seventy-five hundred had never before been to sea; and Martin reported that, deducting officers and petty-officers, he had but twenty-seven hundred seamen to man the fleet. [107]
Hood had gone home the previous November, expecting to return; and the British were now commanded by Admiral Hotham. The latter had cruised off Toulon for three weeks in mid-winter, on account of the indications of the French coming out, and after a succession of most violent weather returned to San Fiorenzo Bay on the 10th of January. He sailed again, apparently about the 22d of the month, to cover a convoy expected from England, leaving in port the "Berwick," seventy-four; which, through the carelessness of her officers, had been permitted to roll her masts overboard at her anchors. After some more hard cruising, the fleet put into Leghorn on the 25th of February, leaving still in San Fiorenzo Bay the "Berwick," the delay in whose repairs can only be attributed to the penury of naval resources. The presence of the fleet in Leghorn was probably necessary both for its own supplies and to remind the wavering Tuscany of the power of Great Britain at her doors; but the "Berwick" incident served powerfully to illustrate the far-reaching effects of individual carelessness and the impolicy of exposing small detachments not covered, directly or indirectly, by the main body. On the 7th of March the French fleet came in sight of Cape Corso, and almost at the same moment discovered the "Berwick," which had only the previous day succeeded in leaving San Fiorenzo for Leghorn. Being still crippled, she was easily overtaken, and forced to surrender at noon.
The following day Hotham in Leghorn learned that the enemy had sailed, and the next morning at dawn put to sea in pursuit. On the 11th the two fleets came in sight of each other, the French far south and to windward of the British, out of gun-shot, and thus continued during the 12th. That night one of the French seventy-fours lost a topmast and parted company, reducing their numbers to fourteen. The following morning the "Ça-Ira," an eighty-gun ship, ran into her next ahead, losing both fore and main topmasts, and thus became the source of anxiety and danger which a crippled ship ever is in the fleet to which she belongs. As she dropped out of the line, a British frigate ran close to her on the side encumbered with the fallen spars, annoying her there for some time with comparative impunity, and was then succeeded by Nelson in the "Agamemnon," who hung about on her quarters until several ships bore down to her relief.
During the night the "Sans Culottes," of one hundred and twenty guns, the heaviest vessel in the French fleet, dropped out of the line to leeward, and in the morning was out of sight. The "Ça-Ira" was taken in tow by, the "Censeur," seventy-four, and at daybreak these two were some distance from, and to the north-east of, their fleet. Both parties were at this time much scattered from the irregularities of the wind; but it shifting now to the north-west favored the British, and those nearest the separated ships speedily brought them to action. While this partial engagement was going on, both fleets shaped their course for the scene, the French intending to cover the "Censeur" and "Ça-Ira" by passing between them and the British, but owing to some misunderstanding this was not done. As the two vans went slowly by on opposite tacks, a sharp exchange of shots took place, in which the British, not being well closed up, were overmatched, and two of their number suffered severely; but as the French allowed the enemy to interpose between them and the disabled vessels, these were forced to surrender after a very gallant resistance, in which they lost four hundred men and were partially dismasted. Each fleet continuing its course in opposite directions, they soon separated and passed out of sight.
The baffling character of the wind, combined with the indifferent sailing qualities of the British three-deckers, deprive this action of any special tactical significance; and the very mediocre calibre of the two admirals was not calculated to overcome the difficulties they encountered. The numerous accidents in Martin's fleet, and the parting of the "Sans Culottes" at such a moment, show the indifferent character of the French captains, and probably justify the comment that Hotham owed his success to the initiative of the admirable officers under his command rather than to his own capacity. "I went on board Admiral Hotham," wrote Nelson, "as soon as our firing grew slack in the van and the 'Ça-Ira' and 'Censeur' had struck, to propose to him leaving our two crippled ships, the two prizes, and four frigates, and pursue the enemy; but he, much cooler than myself, said, 'We must be contented, we have done very well.' Admiral Goodall backed me; I got him to write to the Admiral, but it would not do; we should have had such a day as I believe the annals of England never produced." [108] "Admiral Hotham," says Chevalier, [109] "showed great circumspection. He probably did not appreciate the improvised fleets of the republic. To fight, there are needed ships in good condition, capable seamen, skilful gunners, and officers accustomed to order, to military dispositions, and to squadron manœuvres. These we did not have." "The enemy," wrote Nelson about the same fleet, a few months later, "are neither seamen nor officers." [110] The immediate consequence of this defeat was the abandonment of the projected expedition against Corsica.
After the battle a gale of wind forced the British into Spezia and caused the wreck of the "Illustrious," seventy-four, which, from injuries received in the action, was not able to keep off shore. This, with the capture of the "Berwick," equalized the losses of the two fleets. The French anchored in Hyères Bay, where they were rejoined by the "Sans Culottes," and on the 24th of March returned to Toulon. Admiral Renaudin's arrival from Brest [111] on the 4th of April raised the available force to nineteen or twenty ships-of-the-line; to which the enemy could now oppose only thirteen of their own and two Neapolitan. But, although the British were very destitute of material for necessary equipment and repair, [112] the superiority of organization, discipline, and officer-like training, allowed them little real cause for anxiety. In the month of May a Jacobin outbreak occurred in Toulon. The government had ordered Martin to take advantage of Renaudin's junction, and again to seek the enemy while thus superior. The mob raised the cry that as soon as the fleet sailed the enemies of the Revolution would enter the town and massacre the patriots. The seamen, except those belonging to the Brest squadron, left their vessels, under pretext of deliberating on the dangers of their country, and took part in all the street demonstrations. An expedition was even set on foot against Marseille; but the central government was getting stronger, or rather anarchy was becoming wearisome, and after a paltry engagement the Toulonese fell back upon their city and submitted. A great number of seamen, however, had deserted; and the necessity of recovering them delayed the departure of the fleet, which finally put to sea on the 7th of June with seventeen ships-of-the-line. The time for a favorable sortie was, however, past; the British having at last received a large re-enforcement.
After partially refitting in Spezia, Hotham took his fleet to San Fiorenzo, arriving there on the 30th of March. On the 17th of April he sailed again for Minorca, where he hoped to meet a re-enforcement and a much-needed convoy; but a succession of westerly winds caused the fleet to lose ground, instead of gaining, until the 27th, when it unexpectedly and most fortunately met a body of store-ships from Gibraltar. With these the admiral at once bore up for Leghorn, arriving there next day. Had the French in their own dockyards refitted as rapidly as the British did in a foreign port, and gone to sea with the increase of strength that Renaudin brought, they should have intercepted this important convoy, if they did not bring the fleet to action. The correspondence of Nelson, still a simple captain, testifies continually, in his own vivid style, to the critical state of the campaign at this moment.
On the 8th of May Hotham sailed again for Minorca, and continued to cruise off that island until the 14th of June, when Rear-admiral Robert Mann joined him with a re-enforcement from England of nine [113] ships-of-the-line, making the British superior in number as in quality to the enemy. As a convoy was also expected, the fleet kept the same station until it arrived on the 22d, when the whole body sailed for San Fiorenzo, anchoring there June 29. On the 4th of July Hotham sent Nelson with his own ship and some smaller vessels to co-operate on the Riviera of Genoa with the Austrian advance against the French; but the detachment fell in with Martin's fleet, and had to return to San Fiorenzo, being, says Nelson, "hard pressed" by the enemy, who pursued until they saw the British fleet at anchor. The latter weighed as soon as possible, but did not come up with the French until the 14th, near the Hyères Islands, where a trifling brush took place, resulting in the capture of the "Alcide," seventy-four, which immediately after surrendering caught fire and blew up. This small affair was the last in which Admiral Hotham was directly concerned. Hood had been definitively relieved of the Mediterranean command before he could sail from England on his return; and Hotham, weary of a burden to which he felt himself unfitted and had proved himself unequal, applied for relief, and struck his flag on the 1st of November, 1795.
Prior to the naval brush off Hyères, little had been done in Italy by the armies on either side. The French, whose forces were far inferior to those of the allies and in a state of great destitution, were compelled to stand on the defensive over a very long line, of which the advanced post on the sea was at Vado. The Austrians had imposed upon the Sardinians their own plan of campaign, which was to strike the extreme right of the French at Vado, and then drive them back along the Corniche, while the Sardinians attacked on the other flank through the passes of the Apennines up to the Col di Tende, where the Maritime Alps begin. The British fleet was to co-operate with the movement on the side of the sea—a consideration which had much to do with determining the Austrian plan. By occupying Vado and the Riviera east of it, the coasting trade heretofore carried on from the ports of Genoa and Tuscany to southern France would be stopped; a matter of great consequence to the republic, as those departments only raised grain for three months' consumption and depended for the rest upon that which came from Barbary and Italy by way of Tuscany. With a British squadron at Vado, the populace of Provence, the navy at Toulon, and the army of Italy, would have to be supplied from the north of France by bad inland roads. [114] Vado Bay was, moreover, the best anchorage between Nice and Genoa. Devins, the Austrian general, began his movement on the 13th of June, passing through Genoese territory against the protest of that neutral government. The French resisted sturdily; but the odds were too great, and by the end of June they had fallen back to a line extending from Borghetto on the sea to Ormea in the mountains, abandoning Vado and the intermediate coast towns. Devins now called on Hotham for naval support, and the British admiral detached Nelson, as has already been seen, to give it; but the encounter with the French fleet delaying his arrival for some days served Devins with a pretext for inaction. He employed the mean time in fortifying his position and improving the roads in his rear.

On the 17th of July Nelson reached Genoa, took on board the British minister to that republic, and went to Vado, anchoring there on the 21st. He immediately conferred with Devins, who gave it as his opinion that the Austrians could not advance further until the French were compelled to retire by want of provisions—a result he expected from the action of the navy. Nelson explained to the minister that the food supplies being carried in neutral vessels he was powerless to stop them; for he had stringent orders from the admiralty that no legal measures should be instituted against such, when arrested, until full particulars in each case had been sent to England and instructions had come back what to do. Meanwhile the cargoes, being perishable, would be spoiled. Such utterly inconsequent proceedings, though highly characteristic of the military action of cabinets, were most exasperating to a man of Nelson's temper, always prone to cut knots; but, as he was pecuniarily answerable and a poor man, he could not disregard them on his sole authority. The British ministers to Genoa and Sardinia both concurred in advising him to carry out Devins's wishes; and then Nelson, with the fearlessness of responsibility he always showed—and sometimes out of, as well as in, season—issued orders to his frigates to take every vessel bound to France or to ports within the French lines, to whatsoever nation it might belong. At the same time the general also sent out small cruisers; and it is roundly asserted by Jomini that he laid a tax on all coasting vessels brought in by them, forcing them to pay for a passport and appropriating the proceeds to himself. The utmost diligence, however, could not insure the interruption of a traffic carried on by very small vessels, having to make but short night runs close along a coast; [115] and Nelson's orders, while doubtless productive of some results in stopping large vessels from Tuscany and Algiers, could not prevent supplies getting in by Genoese coasters. The difficulty was increased by the fact that a number of the ports in rear of the French positions belonged to Genoa, and the inhabitants depended upon her for food. To turn a deaf ear to their cries of suffering, and to prevent supplies landed there being used by the French, were alike impossible.
These considerations should have led Devins to regard naval co-operation simply as the efforts of a light force, competent to harass, not to destroy, the enemy's communications; and should have induced him to force his own way, by early and vigorous action, while the French were inferior in numbers and before their positions became too strong. Instead of this, he used the Sardinians and British, not as allies, but as excuses for not moving; action of one kind or another on their part was necessary before he could advance. Thus the summer slipped away, the French busily strengthening their lines and bringing up the army of the Pyrenees to re-enforce that of Italy, after peace was made with Spain. Nelson was full of projects to embark a corps of Austrians, who should seize and occupy a coast position in rear of the French; but Devins only played with a proposition of which Jomini speaks with scant respect, and which was certainly open to the objection that, if carried out with adequate force, it divided the Austrian army. Nelson, it is true, guaranteed its retreat to his ships in case of need; but the Austrian, not unnaturally, preferred a less uncertain line. The British captain, who had at first felt respect for Devins's abilities, wrote on the 17th of September that it had for some time appeared to him "that the general intended to go no further than his present position, and meant to lay the miscarriage of his enterprise against Nice to the non-co-operation of the British fleet and the Sardinian army." [116] Whatever his purpose, Devins did not advance, but quietly awaited the French attack. Early in November a severe illness caused him to give up the command; and on the 23d of the month the enemy, under General Schérer, assaulted vigorously the centre of the allied position, where the Sardinians touched the Austrians. This point had always been weak, and after a short struggle was forced. The original intention of Schérer had been to turn, after piercing the centre, against the Sardinians, as Bonaparte did in the following year; but a very heavy fall of snow in the mountains decided him to swing round to the right, drive the Austrians back upon the coast, and, if possible, anticipate them upon their line of retreat to the eastward. In this he was not entirely successful; but the imminent danger forced the enemy to abandon all their line of works and fall back precipitately, with a loss of seven thousand men, killed, wounded and prisoners, besides their depots at Loano, Vado, and Savona. This action, which was a brilliant and decisive victory, is known as the battle of Loano. By the first of December the Austrians had recrossed the Apennines and were again in the positions from which they had set out the previous June.
The military plan and execution of the campaign by the land forces scarcely falls within the scope of the present work. An advance by the armies of a coalition, whose respective troops and lines of operation are separated by a chain of mountains, even of the height of the Apennines, with difficult communication across them, does not present a combination promising mutual support and probable success. To this disadvantage is to be added that of the long and narrow line by which all the Austrian supplies had to be forwarded; and which any successful advance would make yet longer and more difficult. On the other hand, the Austrians counted much upon the help that could be extended by the navy of Great Britain, in whose interest the occupation of the shore line was undertaken. [117] By their advance they controlled Vado Bay—the best anchorage between Villefranche (Nice) and Genoa; and their presence imposed a restraint upon the latter republic, whose attitude was largely determined by the comparative forces of the belligerents. Did then the British navy, under these circumstances, do all that it could have done to insure the success of the common cause?
