The ordinary cares and duties of his command, and his very extensive correspondence, for the number of letters he was in the habit of writing on service was almost incredible, were by no means Sir Edward's heaviest charge. Perhaps there was no ambassador on whom a greater diplomatic responsibility was imposed than on the commander in the Mediterranean. It formed by much the largest and most anxious portion of Collingwood's duties, and the greatness of the trust, the impossibility of confiding it to another than the commander on the station, and the uncommon ability with which Collingwood sustained it, gave the British Government much uneasiness when the state of that officer's health threatened to deprive them of his services. It increased materially in extent and importance after Sir Edward had succeeded to the command, when the reverses of the French in Russia opened a prospect of deliverance to all the states along the shores of the Mediterranean, including the southern provinces of France itself. Sir Edward exerted himself unceasingly to prepare them for this consummation, and to encourage them to seize the first opportunity to effect it; and the judgment he displayed in these services obtained from a British Cabinet minister the declaration, that "great as he may be as a sea-officer, he is still greater as a statesman."

One professional distinction was yet wanting, and this he anxiously desired, as a means of hastening an honourable peace, and on personal grounds, perhaps, to connect his name with the history of his country—to command in a general action. Though the enemy had shrunk from meeting him, as he expected when he first assumed the command, yet, while they continued to build ships of the largest class, and to keep their fleet always ready for sea, he could not but hope that they only waited for a favourable opportunity to try the fortune of their flag. At the end of 1811 there were sixteen sail of the line in Toulon. Two others were launched next year, and by the close of 1813 there were twenty-two, of which six were three-deckers of the largest size. Sir Edward gave them every opportunity, and every prudent advantage, but he never could induce them to attack him. They had been forbidden to engage, and the Emperor had hitherto seen nothing to induce him to recall the order. Thus, though they were kept in a state of high equipment through the whole period of Sir Edward's command, they never ventured far beyond the protection of the batteries; and came out only when they had a leading wind to return.

The restoration of his fleet was a favourite ulterior object with Napoleon; and if a different result of the Russian campaign had placed the resources of Europe at his command, there is no doubt but that the days of St. Vincent and Trafalgar would have been renewed. There was an English officer who was much in his presence and confidence at Elba, and to whom he proposed the most flattering inducements to enter his service. "I am honoured by your Majesty's offer," was the reply, "but I was born an Englishman." Conversing with him on naval affairs, he one day said, "I would have had two hundred sail of the line, and when I brought against you such a force, you must have been crushed." But the officer soon convinced him that the tactics which he had made so effectual on land, by concentrating an overwhelming force upon his enemy, were not applicable to naval operations. Sailors are made but slowly. It requires an able commander to direct twenty ships, and the most skilful could scarcely manœuvre forty. Dark nights and gales would disperse the unwieldy armada, and a small, but well managed force, would hang upon it and destroy it in detail. The Emperor saw the force of the objections, and closed the conversation with the compliment already related.

Once, towards the end of the war, an opportunity seemed to be offered by which the enemy might be compelled to sacrifice part of his fleet, or to risk a general battle. On the morning of November 5th. 1813, the French fleet had sailed out of Toulon with the wind at E.S.E., and advanced to a greater distance than usual, when the wind suddenly shifted to south-west. Immediately the enemy made every exertion to work back to their harbour. The main body of the British fleet was just in sight to the southward, and an advanced squadron of four sail, with a fifth at no great distance, was about half-way between the two fleets. This squadron lay up for the enemy under all sail, with every appearance of being able to cut off the rear ships, the Wagram of 130 guns, with four two-deckers and four frigates. On the approach of the British, the enemy tacked, and stood in so close, that many thought they intended to run themselves on shore; but they again tacked off to the southward, and the advanced squadrons stood on with every prospect of passing to windward of them. Unfortunately, as the British ships approached, the wind headed them, and threw them off so much, that they only fetched just within gun-shot of the Wagram, the enemy's rear ship. The fleet was at this time bringing up the original wind, and the Caledonia, San Josef, and Boyne, actually fetched within gun-shot of the French Admiral, before the wind headed them. The Wagram, which had reserved her fire for the Caledonia, exchanged broadsides with her, but at too great a distance to produce material effect; and the enemy being so far to windward, succeeded in reaching Toulon. Eleven shots from the Wagram and the batteries struck the Caledonia, wounding the mainmast, cutting some of the shrouds, and destroying a small boat upon the booms. Much disappointment was felt by all the fleet, and the conduct of the advanced squadron was strongly censured by many in the ships astern, who supposed that they had intentionally bore away, when in fact they had come up within influence of the head wind.

A more serious, though very partial affair occurred in the following February. On the evening of the 12th, Rear-Admiral Kosmao Kerjulien sailed from Toulon, with three sail of the line, and three frigates, to escort a seventy-four which was expected from Genoa. On the following morning, the fleet returning from Mahon, discovered the enemy to the eastward of Hyères Islands. They were at first supposed to be British ships, but the Admiral himself going aloft, clearly made out their character. The Boyne, Captain Burlton, a small three-decker, sister ship to the Victory, was considerably in advance of the fleet. It was on Sunday, and the ships were preparing for the morning service, which had already commenced on board the Boyne, when the signal for a general chase was thrown out. The wind blew strong from E.S.E., and the Boyne, perceiving the enemy's intention to come through the little pass of Hyères Bay, stood for that pass to intercept them. Sir Edward, who was leaning on the foreyard, watched her with admiration, but extreme anxiety. "Hold on, my brave Burlton!" he exclaimed, as the Boyne dashed at their whole force. Then, as he feared they would all close, and overpower her before he could arrive to her assistance, he turned to an officer at his side, and declared with energy, "If they take her they sha'nt keep her, for I'll go in with the fleet!"

Passing through the enemy immediately astern of a frigate, to which she gave a broadside, the Boyne separated the rear-ship from the others, and brought her to action. This ship, the Romulus, a two-decker, immediately hauled in for the north shore, and kept so close, going round all the bays, that the Boyne could neither run her on board, nor get inside her. They ran side by side with studding sails set, and at the rate of ten knots, before the wind, which blew directly into Toulon. Once it was thought that the Romulus was aground, as she luffed up to the wind, which brought all her sails aback, and her starboard lower studding-sail in upon the gangway. The Boyne also backed her sails, and continued close to the enemy; but the Romulus paying off, and filling again, continued to run alongshore, and when she reached Cape Brun, at the entrance of the harbour, had gained on the Boyne. The Caledonia had by this time come up, and the Admiral waved to Captain Burlton to haul his wind to the southward. The Boyne tacked accordingly, being then within pistol shot of Cape Brun battery; and the Caledonia fired a broadside at the Romulus, as she ran in to join her consorts in the harbour. The Caledonia then gave the Boyne three hearty cheers, and Captain Burlton received the thanks of the commander-in-chief by signal.

Napoleon was now contending for existence on the soil of France, and the remains of his former conquests were rapidly melting from him. In the course of January and February, every place in the Adriatic had surrendered. In the following month, Lord William Bentinck left Palermo with an army, supported by a squadron under Commodore J. Rowley, to reduce Genoa. The advanced guard was landed considerably to the eastward, and moved forward, supported by the squadron, carrying and dismantling the batteries as they advanced. On the 30th, the defences round the Gulf of Spezzia capitulated. On the 13th of April, the army was landed at Recce, in the Gulf of Genoa; and at day-break on the 17th, a joint attack was made by the land and sea forces on the defences around the place. These were carried in the course of the day; and preparations were in progress to attack the town, when Sir Edward Pellew arrived with several line-of battle ships. The governor, already alarmed at the rapid progress of the assailants, capitulated, and the town was taken possession of next morning. Four gun-brigs, and a number of merchant vessels were found in the mole; and the Brilliant, a fine seventy-four on the stocks, was launched, and still remains in the navy under the appropriate name of the Genoa.

Paris had already capitulated; and on the 28th of this month, Napoleon left France in a British frigate for Elba. He landed on the 3rd of May on the little island which had been assigned to him for a sovereignty, and a prison: and thus ended a war, one of the longest, the most dreadful, but in all respects the most glorious, which England had ever waged.
