Sir Sidney's imprisonment was at first in the Abbaye, which had been made so infamously memorable by the slaughters of September 1793. He was afterwards placed in the prison of the Temple. In all probability, the first object was to exhibit him to the Parisians. An English captain as a prisoner was a rare exhibition, and his detention also saved them from the most active disturber of their Norman and Breton navigation. But his confinement was not strict, and he was even suffered occasionally to walk about Paris on giving his parole to the jailer. At length, after various British offers of exchange, which were all rejected by the French, he escaped by a counterfeit order of liberation; and, encountering several hair-breadth hazards, reached Havre, seized a boat, put off, and was taken up at sea by the Argo frigate, commanded by Captain Bowen, who landed him at Portsmouth, and he arrived in London in April 1798, having been in France about two years and a month.

It is sometimes difficult to know, respecting any event, peculiarly in early life, whether it is a misfortune or the contrary. Sir Sidney's capture must have been often felt by him as the severest of calamities, by stopping a career which had already made him one of the national favourites, and had given him promise of still higher distinction. From the command of the Diamond to the dreary chambers of the Temple was a formidable contrast; yet the event which placed him there may have been an instance of something more than what the world terms "good luck." If he had remained in command of his frigate, he might have fallen in some of those fights with the batteries and corvettes which he was constantly provoking. But in his French prison he was safe for the time, and yet not less before the public eye. In reality, the sympathy felt for him there, and the fruitless attempts of the Admiralty to effect his exchange, kept him more the Lion than before; and he returned just in time, to be employed on a service of the first importance, and which, by its novelty, adventure, and romantic peril, seemed to have been expressly made for his genius.

The French expedition, under Napoleon, had taken possession of Egypt; the Turks were a rabble, and were beaten at the first onset. The Mamelukes, though the finest cavalry in the world as individual horsemen, were beaten before the French infantry, as all irregular troops will be beaten by regulars. At this period, the object of the ministry was to excite the indolence of the Turkish government to attempt the reconquest of Egypt, and Sir Sidney was appointed to the command of Le Tigre, a French eighty gun-ship, which had been captured by Lord Bridport three years before. If it be said that he owed this command in any degree to his having been sent on a mission to Turkey some years before, which is perfectly probable; let it be remembered, that that mission itself was owing to the gallantry and intelligence which he had displayed in his volunteer expedition to Sweden. Sir Sidney's present appointment was a mixture of diplomacy with a naval command; for he was appointed joint-plenipotentiary with his brother Spencer Smith, then our minister at Constantinople. But this junction of offices produced much dissatisfaction in both Lord St Vincent and Nelson; and it required no slight address, on the part of Sir Sidney, to reconcile, those distinguished officers to his employment. However, his sword soon showed itself a more effectual reconciler than his pen, and the siege of Acre proved him a warrior worthy of their companionship. After the siege, Nelson, as impetuous in his admiration as he was in his dislikes, wrote, to Sir Sidney the following high acknowledgment:—

"My dear Sir,—I have received, with the truest satisfaction, all your very interesting letters, to July. The immense fatigue you have had in defending Acre against such a chosen army of French villains, headed by that arch-villain Buonaparte, has never been exceeded; and the bravery shown by you and your brave companions is such as to merit every encomium which all the civilised world can bestow. As an individual, and as an admiral, will you accept of my feeble tribute of praise and admiration, and make them acceptable to all those under your command?

"Nelson.

"Palermo, Aug. 20, 1799."

Sir Sidney found the Sultaun willing to exert all the force of his dominions, but wretchedly provided with the means of exertion—a disorganised army, an infant navy, empty arsenals, and all the resources of the state in barbaric confusion. Two bomb-vessels and seven gun-boats were all that he could procure for the coast service. He ordered five more gun-boats to be laid down, waiting for guns from England. But he was soon called from Constantinople. Advice had been received by the governor of Acre, Achmet Pasha, that Buonaparte, at the head of an army of twelve or thirteen thousand men, was about to march on Acre. The position of this fortress renders it the key of the chief commerce in corn at the head of the Levant, and its possessor has always been powerful. Its possession by the French would have given them the command of all the cities on the coast, and probably made them masters of Syria, if not of Constantinople. Buonaparte, utterly reckless in his cruelties, provided they gained his object, had announced his approach by the following dashing epistle to the Pasha:—"The provinces of Gaza, Ramleh, and Jaffa are in my power. I have treated with generosity those of your troops who placed themselves at my discretion. I have been severe towards those who have violated the rights of war. I shall march in a few days against Acre." His severity had already been exhibited on an unexampled scale. Having taken Jaffa by assault, and put part of the garrison to the sword, he marched his prisoners, to the number of three thousand seven hundred, to an open space outside the town. As they were disarmed in the town, they could make no resistance; and, as Turks, they submitted to the will of Fate. There they were fired on, until they all fell! When this act of horrid cruelty was reported in Europe by Sir Robert Wilson, its very atrocity made the honourable feelings of England incredulous; but it has since been acknowledged in the memoir by Napoleon's commissary, M. Miot, and the massacre is denied no longer. The excuse which the French general subsequently offered was, that many of the Turks had been captured before, and liberated on parole; that having thus violated the laws of war, he could neither take them with him, nor leave them behind. But the hollowness of this excuse is evident. The Turks knew nothing of our European parole; they felt that it was their duty to fight for their Pasha; they might have been liberated with perfect impunity, for, once deprived of arms, and stript of all means of military movement, they must have lingered among the ruins of an open town, or dispersed about the country. The stronger probability is, that the massacre was meant for the purposes of intimidation, and that on the blood of Jaffa the French flag was to float above the gates of Acre.

It is satisfactory to our natural sense of justice, to believe that this very act was the ruin of the expedition. Achmet Pasha was an independent prince, and might have felt little difficulty in arranging a treaty with the invader, or receiving a province in exchange for the temporary use of his fortress. But the bloodshed of Jaffa must have awakened at once his abhorrence and his fears. The massacre also excited Sir Sidney's feelings so much, that he instantly weighed anchor, and arrived at Acre two days before the French vanguard. They were first discovered by Le Tigre's gun-boats, as the heads of the column moved round the foot of Mount Carmel. There they were stopt by the fire of the boats, and driven in full flight up the mountains.

But another event of more importance occurred almost immediately after. A flotilla was seen from the mast-head of Le Tigre, consisting of a corvette and nine sail of gun-vessels. The flotilla was instantly attacked, and seven struck, the other three escaped, it being justly considered of most importance to secure the prizes, they containing the whole battery of artillery, ammunition, &c., intended for the siege. Previously to his arrival, Sir Sidney had sent Captain Miller of the Theseus, a most gallant officer, and Colonel Phelypeaux, to rebuild the walls, and altogether to put the place in a better defensive order. Nothing could be more fortunate than this capture, for it at once gave Sir Sidney a little fleet, supplied him with guns and ammunition for the defence of the place, and, of course, deprived the French of the means of attack in proportion. But it is not to be supposed that Napoleon was destitute of guns. He had already on shore four twelve-pounders, eight howitzers, a battery of thirty-two pieces, and about thirty four-pounders. The siege commenced on the 20th of March, and from that day, for sixty days, was a constant repetition of assaults, the bursting of mines, and the breaching of the old and crumbling walls.

At length Buonaparte, conscious that his character was sinking, that he was hourly exposed to Egyptian insurrection, that the tribes of the Desert were arriving, and that every day increased the peril of an attack on his rear by an army from Constantinople, resolved to risk all upon a final assault. After fifty days of open trenches, the Turkish flotilla had been seen from the walls. The rest deserves to be told only in the language of their gallant defender.

"The constant fire of the besiegers was suddenly increased tenfold. Our flanking fire from afloat was, as usual, plied to the utmost, but with less effect than heretofore, as the enemy had thrown up epaulements of sufficient thickness to protect them from the fire. The French advanced, and their standard was seen at daylight on the outer angle of the town, which they had assaulted. Hassan Bey's troops were preparing to land, but their boats were still only halfway to the shore."

It was at this moment that the spirit and talents of Sir Sidney had their full effect. If he had continued to depend on the fire of his boats, the place would have been taken. The French were already masters of a part of the works, and they would probably have rushed into the town before the troops of Hassan Bey could have reached the shore.
