The Orion was now completely worn out, having been continuously in commission since the war began in 1793. Besides the three general actions in which Saumarez commanded her, she had borne a valiant part in Howe's great battle of the 1st of June. "This last business has so shattered the poor Orion" wrote Saumarez, "that she will not, without considerable repairs, be in a state for more service." On reaching England she was paid off; and in February, 1799, he was appointed to the Cæsar, of eighty-four guns, one of the finest ships in the navy, which was to bear his flag in the last and most brilliant episode of his hard-fighting career.

A year later, Lord St. Vincent, having returned from the Mediterranean, took command of the Channel Fleet, and at once instituted in its methods, and particularly in the blockade of Brest, changes which gradually revolutionized the character of the general naval war; baffling beyond any other single cause the aims of Napoleon, and insuring the fall of his empire. One of the new requirements was the maintenance of a powerful advanced division of six or eight ships-of-the-line, within ten miles of the harbor's mouth. It was a duty singularly arduous, demanding neither dash nor genius, but calmness, steadiness, method, and seamanship of a high order, for all which Saumarez was conspicuous. From either side of the Bay of Brest a long line of reefs projects for fifteen miles to the westward. Far inside their outer limits, and therefore embayed by the westerly winds which blow at times with hurricane violence, was the station of the advanced squadron, off some well-marked rocks of the northern reef, known as the Black Rocks. On this spot, called Siberia by the seamen, during fifteen weeks, from August to December, Sir James Saumarez kept so close a watch that not a vessel of any force entered or left Brest. "With you there," wrote Earl St. Vincent, "I sleep as sound as if I had the key of Brest in my pocket." No work ever done by him was more meritorious or more useful. Near its expiration St. Vincent wrote to him, "The employment you have conducted is the most important of this war." He there demonstrated that what before had apparently been thought impossible could be done, though involving a degree of anxiety and peril far exceeding that of battle, while accompanied by none of the distinction, nor even recognition, which battle bestows. "None but professional men who have been on that service," says his biographer with simple truth, "can have any idea of its difficulties,—surrounded by dangers of every kind, exposed to the violence of storms, sailing amidst a multitude of rocks and variable currents in the longest and darkest nights, and often on a lee shore on the enemy's coast, while the whole of their fleet is near, ready to take advantage of any disaster." Collingwood, who in the next war succeeded to the same unenviable duty, wrote home that, even in the summer month of August, "I bid adieu to comfortable naps at night, never lying down but in my clothes. An anxious time I have of it, what with tides and rocks, which have more of danger in them than a battle once a week." In this laborious task Saumarez was the patient, unobserved pioneer.

There was one man, however, who could and did recognize to the full the quality of the work done by Saumarez, and its value to those sagacious plans which he himself had framed, and which in the future were to sap the foundations of the French power. That man was St. Vincent. "The merit of Sir James Saumarez," he said, "cannot be surpassed;" and again, to Saumarez himself, "The manner in which you have conducted the advanced squadron calls upon me to repeat my admiration of it." Succeeding soon after to the post of First Lord of the Admiralty, he gave him an opportunity for distinction, which resulted in an action of singular lustre and striking success.

Bonaparte, long before returned from Egypt, and now, as First Consul, practically the absolute ruler of France, had overthrown all enemies on the Continent. Peace with Austria, after her disasters of Marengo and Hohenlinden, had been signed in February, 1801. The great objects of the French ruler now were to compass a maritime peace and withal to retain Egypt, associated from far back with the traditional policies of France, and moreover a conquest in which his own reputation was peculiarly interested. To compel Great Britain to peace, he sought, by diplomacy or force, to exclude her commerce from the Continent, as well as to raise up maritime enemies against her. Thus he had fostered, if not actually engendered, the Baltic league of 1801, shattered by Nelson at Copenhagen; and for this purpose he intended to occupy both Portugal and the kingdom of Naples. A powerful British expedition against Egypt had entered the Mediterranean. It was essential either to attack this directly, or to cripple its communications. Unable to do the former, and persistently thwarted in his attempts to reinforce his own troops in that distant dependency by the close watch of the British navy, of which Saumarez gave so conspicuous an illustration before Brest, Napoleon resorted to the common and sound military expedient of collecting a threatening force upon the flank of his enemy's line of communications. He directed a concentration of the Spanish and French navies at Cadiz, which, by its nearness to the straits, met the desired requirement. Among others, three French ships were ordered thither from Toulon.

The British ministry was informed that at Cadiz were collecting Spanish vessels, said by report to be intended against Portugal. This is unlikely, as Bonaparte could have subdued that country from the land side by the assistance of Spain; moreover, the object of the concentration is stated in his letters. A squadron of five ships-of-the-line was accordingly formed, and placed under the command of Saumarez, who on the 1st of January, 1801, had been made a rear admiral. His orders were to go off Cadiz, where he would find two more vessels, and to prevent the enemies within the port from sailing, or from being joined by any from outside. Whatever Bonaparte's object, it would be thwarted by a force thus interposed, in a position to meet either one or the other of the converging detachments before they could unite.

Saumarez sailed on his mission June 16, 1801, and on the 28th arrived off Cadiz. On the 5th of July he was informed that three French ships had anchored off Algeciras, the Spanish port on the west side of Gibraltar Bay, confronting the British fortress on the east side. This was the division from Toulon, which upon reaching the straits first learned of the British squadron that effectually prevented its entrance to Cadiz.

Saumarez at once started for Algeciras with six of his ships-of-the-line, the seventh being out of recall to the northward. The following day, July 6th, he entered the bay, and found the French moored in a strong position, under cover of Spanish land batteries, and supported by a number of gunboats. Still, though difficult and doubtful, the enterprise was not hopeless; and, as the breeze allowed his vessels to head for the enemy, he steered to engage at once. Unfortunately, the wind fell as the squadron drew nigh, and only four ships were able to take their intended places; the other two had to anchor outside their consorts, and fire as they could through the intervals. This mishap lessened by one-third the fighting power of the British, and, coupled with the acknowledged superiority of guns on solid ground over those afloat, reduced them to inferiority. Their disadvantage was increased by the arrangements of the French admiral, carefully elaborated during the two preceding days. Had the preparations of Brueys at the Nile equalled those of Linois at Algeciras, Nelson's task must have been harder and his victory less complete. Nevertheless, after an engagement of an hour and a half, the British fire so far prevailed that the enemy resorted to a measure for which precautions had been taken beforehand. Lines had been run from each French ship to the shoal water lying close inside them; and by means of these they were warped away from their opponents until they took the ground. This increase of distance was in every way a gain to the party standing on the defensive, and a corresponding loss to the assailants. Saumarez ordered the cables cut and sail made to close once more; but the light and fickle airs both baffled this effort and further embarrassed the British, through the difficulty of keeping their broadsides in position. Here happened the great disaster of the day. One of the outer ships, the Hannibal, tried to pass inside the headmost of the French, not realizing that the latter had moved. In so doing she ran aground close under a battery, to whose fire she could make no reply. After a brave and prolonged resistance, in which she lost seventy-five killed and seventy wounded out of a crew of six hundred, and had many of her guns dismounted, she hauled down her flag. By this time another ship, the Pompée, was dismasted, and success was plainly hopeless. The British admiral, therefore, ordered the action discontinued, and withdrew to the Gibraltar side; the Pompée having to be towed away by the boats of the squadron.

Saumarez had failed, and failure, however explained, can hardly be carried to a man's credit; but his after course, by wresting success out of seemingly irretrievable disaster, has merited the highest eulogium. Maintaining both courage and energy unimpaired, every effort was instantly made to get the ships once more into fighting condition, that the attack might be renewed. "Tell the Admiralty," said he to the bearer of his despatches, "that I feel confident I shall soon have an opportunity of attacking the enemy again, and that they may depend upon my availing myself of it."

The opportunity did come. On the morning of July 9th, the Superb, the seventh ship, which had not been in the action, was seen rounding the west point of the bay under all sail, with a signal flying that the enemy was in pursuit. A few moments later appeared five Spanish vessels, two of which, the Real Carlos and the Hermenegildo, carrying each one hundred and twelve guns, were among the largest then afloat. On board them had embarked a number of the jeunesse dorée of Cadiz, eager to join the triumphal procession which it was thought would soon enter the port, flushed with a victory considered by them to be rather Spanish than French, and escorting the rare trophy of a British ship-of-the-line that had struck to Spanish batteries. Besides the two giants, there were a ninety-gun ship and two seventy-fours; and the next day a French vessel of the latter class joined, making a total reinforcement of six heavy ships.

To these Saumarez could oppose but five. The Hannibal he had lost. The Pompée could not be repaired in time; her people were therefore distributed among the other vessels of the squadron. Even his own flag-ship, the Cæsar, was so injured that he thought it impossible to refit her; but when her crew heard his decision, one cry arose,—to work all day and night till she was ready for battle. This was zeal not according to knowledge; but, upon the pleading of her captain in their name, it was agreed that they should work all day, and by watches at night. So it happened, by systematic distribution of effort and enthusiastic labor, that the Cæsar, whose mainmast on the 9th was out and her rigging cut to pieces, was on the 12th able to sail in pursuit of the foe.
