Meanwhile the return of Nelson to the Neapolitan coast intoxicated that Court with joy. Queen Maria Carolina, ever the moving spirit at Naples, now laid her plans for the expulsion of the French from Italy. Trusting to her influence over her son-in-law, Francis II, and to a defensive compact which the Courts of Vienna and Naples had framed on 20th May 1798, she sought to incite him to take the offensive. Her close friendship with Lady Hamilton, wife of the British ambassador at Naples, also enabled her to gain complete ascendancy over Nelson, who, with his usual hatred of "the French villains," counselled open and immediate war. For abetting this design, Sir William Hamilton received a sharp rebuke from Downing Street. Francis II and Thugut were even more annoyed. They repulsed the Neapolitan emissary who begged for help, and roundly accused the Pitt Ministry of inciting Naples to war in order to drag in Austria. Their anger was not appeased by the successes of the Neapolitans near Rome, which the French evacuated on 29th November. The counter-stroke soon fell. The French, rallying in force, pushed the Bourbon columns southwards; and the early days of 1799 witnessed in swift succession the surrender of Naples, the flight of its Court and the Hamiltons to Palermo on Nelson's fleet, the foundation of the Parthenopean Republic, and the liquefaction of the blood of St. Januarius in sign of divine benediction on the new régime.[510]

Nevertheless, Nelson and the royal fugitives had set in motion forces which elsewhere made for triumph. Paul, re-assured as to England's desire to re-establish the Order of St. John at Malta, entered into an alliance with her on 29th December 1798, whereby the two Powers agreed to reduce France within her old boundaries, Russia furnishing to England an army of 45,000 men, mainly with a view to the support of Prussia, on condition of receiving £75,000 per month and three months' subsidies in advance. She also promised to send 3,000 men to help in the siege of the French garrison at Malta and others to assist England in the defence of the Neapolitan lands. Austria, resentful towards Pitt and fearful of Prussia's designs, still held back, though the events in Italy, especially the dethronement of Charles Emmanuel IV of the House of Savoy by the French should have spurred her to action. Probably she waited until the needs of England and Russia should enable her to dictate her terms. The cupidity of Thugut had been whetted by Pitt's speech as to the wealth of England; and the efforts of Cobenzl at St. Petersburg led Whitworth to sign a compact on terms so onerous to the British Treasury as to draw on him a sharp disclaimer and reprimand from London.[511] So matters dragged on far into the year 1799, when plans for the ensuing campaign ought to have been matured.

Still more luckless were the dealings of the British Cabinet with Prussia. In the hope of winning over Frederick William III, Grenville in November 1798 despatched his brother Thomas on a mission to Berlin. His journey thither was one of the longest and most eventful on record. At Yarmouth he was detained by easterly gales; and when at last the packet boat made the mouth of the Elbe it was wrecked. The passengers and crew succeeded in making their way to shore over the pack-ice, Grenville saving his papers, except the "full-power" needful for signing a treaty. He reached Cuxhaven in great exhaustion; and arrived at Berlin on 17th March, only to find that the French by daring and intrigue had cowed the North German States into subservience. The terrible winter of 1798–9 largely accounts for the delays which ruined the subsequent campaign. Whitworth remained long without news from Downing Street; and at last, on 12th February, announced that he had received nine posts at once. Meanwhile France, controlling all the coasts from Bremen to Genoa, not only excluded British messengers, but carried on her diplomatic bargaining in Germany without let or hindrance. For all his trouble, Thomas Grenville could get no firm footing amidst the shifting sands of Prussian diplomacy. So nervous were the Austrian Ministers as to Prussia's future conduct that they seemed about to come to terms with France and join in the plunder of the smaller German States. This might have been the upshot had not French armies crossed the Rhine (1st March 1799), and shortly afterwards invaded the Grisons Canton.[512] Goaded to action, Francis II declared war eleven days later. On 28th April Austrian hussars seized the French envoys withdrawing from Rastatt, murdering two of the four and seizing the papers of all.

Thus began the war of the Second Coalition. Bonaparte's seizure of Malta and Egypt without a declaration of war, and the unbearable aggressions of the French in Switzerland, Italy, and on the Rhine, stirred to action States which the diplomatic efforts of Pitt and Grenville had left unmoved. For none of the wars of that period was France so largely responsible. Even now, when the inroad of the French into Germany threatened the ascendancy of Prussia, Frederick William declined to join the Allies; and his unstatesmanlike refusal thwarted the plans of Pitt for the march of the subsidized Muscovite force through Prussia for the recovery of Holland.

Another essential point was Switzerland. Like a bastion frowning over converging valleys, that Alpine tract dominates the basins of the Po, the Inn, the Upper Rhine, and the Upper Rhone. He who holds it, if strong and resolute, can determine the fortunes of North Italy, Eastern France, South Germany, and the West of the Hapsburg domains. Further, by closing the passes over the Alps he can derange the commerce of Europe; and the sturdy mountaineers will either overbear the plain-dwellers, or will serve as mercenaries in their forces. Accordingly Switzerland, like her Asiatic counterpart, Afghanistan, has either controlled her neighbours, or has been fought for by them. As commerce-controller, provider of troops, and warden of the passes, she holds a most important position. Fortunate it is that the Swiss have loved freedom, or money, more than dominion. For so soon as a great State possesses their land, the Balance of Power becomes a fiction.

Pitt evinced sure insight in his resolve to free the Switzers from the Jacobin yoke. To it the men of the Forest Cantons succumbed only after desperate struggles, which inspired Wordsworth with one of the noblest of his sonnets. There is no sign that Pitt set much store on winning over the public opinion of Europe by siding with the oppressed against the oppressor, as his disciple, Canning, did during the Spanish National Rising; but help from the Swiss was certainly hoped for. So early as August 1798 Pitt proposed to allot £500,000 for assistance to them, and, but for the delays at St. Petersburg and Vienna, the Allies might have rescued that brave people before it fell beneath the weight of numbers. Even in March 1799, when the rising against the French had scarcely begun, he set apart £31,000 per month for the purpose of equipping a corps of 20,000 Swiss. On 15th March, after hearing of the outbreak of war on the Rhine, Grenville urged that the Russian force subsidized by England should march towards Switzerland, now that Prussia's doubtful behaviour prevented a conquest of Holland by land. He also insisted that this addition to the allied forces destined for Switzerland must not be allowed to lessen the number of Austrians operating there.[513]

The Court of Vienna at once saw in the subsidized Russian army a tool useful for its own plans, and requested that it should serve with the Austrians in Swabia. The answer to this singular request can be imagined. For a day or two Whitworth was also disturbed by a belated effort of the French Directory to restore peace. It offered Poland to the Elector of Saxony, and Saxony to Prussia for her friendly services, Austria being led to expect Bavaria, if she would keep Russia "within her ancient limits." Whitworth mentioned this overture to Cobenzl, and saw him blush for the first time on record.[514] Probably, then, the scheme had some powerful backing; but now Austria had crossed the Rubicon.

At first all went well. The French had played a game of bluff which they could not sustain. On all sides they were worsted in a way which suggests how decisive the campaign might have been had the Allies heartily seconded the salutary plans of Pitt. Unfortunately, despite his efforts, no compact came about between Great Britain and Austria. Russia and the Hapsburg State were but loosely connected; and, owing to a long delay in the arrival of the ratification of the Anglo-Russian Treaty, Paul did not until the beginning of May send forward the subsidized army under the command of Korsakoff.

On the other hand, the auxiliary Russian force sent forward to the help of Austria had by that time helped the white-coats to win notable triumphs in North Italy. In the months of April and May, Melas and the Imperialists, powerfully backed by Suvóroff's Muscovites, carried all before them, and drove the enemy from Milan. Soon afterwards the Allies entered Turin; and only by hard fighting and heavy losses did Moreau with the chief French army cut his way through to the Genoese coast. Meanwhile General Macdonald, retiring with a French corps from Naples, left that city to the vengeance of Nelson and Maria Carolina with results that are notorious. The French general made a brave stand in North Italy, only to fall before the onsets of the Allies at the Trebbia (17th–19th June). He, too, barely escaped to Genoa, where the relics of the two French armies faced about. These successes aroused the highest hopes at Westminster. Canning, who resigned his Under-Secretaryship of Foreign Affairs in March 1799, wrote that he cared not whether the Austrians were beaten; for their failure would serve as a good example to Europe. But in June, after their brilliant successes, he expressed a confident hope of the collapse of "the monstrous fabrick of crimes and cruelties and abominations" known as French policy; he added that Prussia could not be so stupid as to hold aloof from the Coalition; and that Pitt, again vigorous in mind and body, would carry through the war to the end.
