Further, on 14th September, despite bad news from Dunkirk, Dundas issued orders that 4,000 Hessians, serving under the Duke of York, must be withdrawn in order to strengthen the garrison at Toulon, their place being taken by others hired at Cassel. On 28th September Dundas added that the artillery sent for Dunkirk would be withdrawn from Flanders as it was urgently needed at Toulon. Thus these two expeditions competed together, and produced a dislocation of plans and ordering of troops to and fro, which told against success in either quarter. By 27th October Ministers definitely decided that Toulon, or la Vendée, was a better fulcrum for their scanty forces than Flanders.[245] Even so, with all these dislocations of the Flemish plans, Pitt and Dundas relied too much upon Austria; and all too late found out that she was a broken reed. The Sardinians, also, lacking due support from the Court of Vienna, were afraid to denude their borders and therefore sent an inadequate contingent, despite the fact that they had promised to place 20,000 troops at the disposal of England free from all expense.
Far different was the procedure of the French. Carnot determined to retake Lyons and Toulon, even if the efforts against Spain and Sardinia had to be relaxed. Further, on the 16th of September there arrived at the Republican army west of Toulon the incarnation of warlike energy and skill. At the bidding of the Commissioners of the Convention, Napoleon Bonaparte had come from the arsenal at Marseilles to assist the few artillerymen then before Toulon. On the 17th he was placed in command of their insignificant siege artillery, and forthwith from the slopes two miles west of the town he opened fire on the nearest ships. It is incorrect to claim for him the origination of the plan of sinking the fleet by a fire from the height behind l'Eguilette; for three days earlier the Commissioners of the Convention had written that they would secure a position whence the allied fleet could be sunk by red-hot cannon-balls; and there was no point but the high ground behind Fort l'Eguilette which dominated both the inner and the outer harbours.[246] But it may freely be granted that Bonaparte clinched the arguments in favour of this course and brought to bear on it that masterful energy which assures triumph. It was the first occasion on which he crossed the path of Pitt; and here, as always, he had the advantage of a central position, and of wielding a compact and homogeneous force against discordant Allies.
The worst difficulty confronting the defenders of Toulon remains to be noted. There the Sea Power is at the mercy of the Land Power. To attempt to defend that city at the head of its land-locked harbour, dominated by promontories, was to court disaster unless the fleet had an army to protect it. In such a case a fleet is a source of danger rather than of safety. Its true function is to act where it can, either directly or indirectly, command the land. It operates with most effect against low and exposed coasts. St. Jean d'Acre affords, perhaps, the best example of a town at the mercy of a fleet. Portsmouth, Sydney, Brest, and Toulon cannot be held by an enemy unless he brings forces sufficient to hold the neighbouring heights. In occupying Toulon, the Sea Power was virtually putting its head into the lion's jaw. Only by degrees did the authorities at home understand this all-important fact. For some time it was veiled from Pitt; and, as we shall see, the Austrian Chancellor, Thugut, never did understand it. To those who were on the spot, the need of occupying the promontory behind l'Eguilette was apparent; and on 21st September Lord Mulgrave and Rear-Admiral Gravina led a force to seize the very height on which Bonaparte's will had already fastened. The Allies crowned it with a temporary work dignified by the name of Fort Mulgrave. The fortunes of Toulon turned on the possession of all the heights commanding the harbour, but especially of this one.

Even before the arrival of Bonaparte the difficulties of defence were very great. A British naval officer wrote on the 14th to Lord St. Helens, British ambassador at Madrid, that the situation of the little garrison was very critical owing to daily attacks from the 5,000 French at Ollioules and the same number on the eastern side. The Allies, he added, could not wholly trust the French royalists serving with them, and they were glad to send away on four French sail-of-the-line some 6,000 French sailors who had bargained to be landed on the Biscay coast. Having only 1,570 British and 3,460 Spaniards, they could scarcely man the ramparts and forts, several of which, especially those on Mount Faron, were not nearly ready. The houses of the town were far too near to the ramparts; but the Allies dared not demolish them until reinforcements arrived. Fortunately the Spanish Admiral, Gravina, was alert, intelligent, and trustworthy; and Piedmontese were known to be advancing over the Maritime Alps into the county of Nice. Part of Hood's fleet was engaged in intercepting the supplies and stores destined for the Republicans.[247]
The letter brings out vividly the perils of the garrison, which must have evacuated Toulon had not reinforcements speedily arrived. On 26th September Hood wrote that the Allies were kept in perpetual alarm by the French batteries, which must be kept under at all risks, until more troops arrived.[248] Fortunately the foresight of Pitt and Grenville had provided the means of backing up operations in the Mediterranean. Apart from the treaty with Sardinia, there was a compact with Naples, whereby that Court promised a force of 6,000 men and 12 warships, the naval expenses being borne by England.[249] By 5th October 1,350 Sardinian and 4,000 Neapolitan troops arrived, thus enabling the garrison to hold up against the ever increasing forces of the Republicans. On the other hand, the fall of Lyons on 9th October set free large numbers who were available for service at Toulon. Consequently the troops and seamen of the Allies were persistently overworked, so that Hood was constrained to hire 1,500 Maltese seamen, to take the place of those serving the batteries. At first only 750 British troops could be spared from Gibraltar; but by the end of October, when further help was at hand, the allied forces (rank and file) stood as follows:
| British | 2,114 |
| French Royalists | 1,542 |
| Spaniards | 6,840 |
| Neapolitans | 4,832 |
| Sardinians | 1,584 |
| ——— | |
| 16,912 |
So exacting was the service, and so unhealthy the season (it cost Bonaparte a sharp attack of malarial fever), that the number fit for duty did not exceed 12,000.
