The abdication of Napoleon, 6th April, 1814, and the restoration of the Bourbons followed, and Admiral Penrose left the Gironde on May 22nd, and returned to Passages to superintend the embarkation of the troops and stores. The difficulties were great. The inadequate supply of transports precluded the affording, even to the sick and wounded, the accommodation of which they were in need; and the hatred borne by the Spanish population to the British troops burst forth more and more as their strength diminished. Although English blood and treasure had been poured forth to assist Spain against the despotism of Napoleon and in driving the French out of the country, not a spark of gratitude was manifested by the Spaniards. It was thought on this occasion highly probable that some outrage would be attempted in the rear of the embarkation. Indeed, a plan had been formed by some Spaniards to seize the military chest, and for security it had to be conveyed on board the _Lyra_, and a volley of stones was hurled at the last boat that left the shore. During Admiral Penrose's whole stay on this ungrateful coast, he never received a visit or the smallest mark of attention from a single Spaniard; and on his leaving Passages, not one individual in the town was seen to look out of a window to watch the sailing of the fleet. The _Porcupine_ anchored in Plymouth Sound, September 6th, and the Admiral struck his flag on the 12th, with but little expectation, now that peace had revisited Europe, of being again actively employed. On the 16th, however, he received a letter from Lord Melville, offering him the command of the fleet in the Mediterranean, become vacant by the recall of Admiral Hallowell. The offer was accepted, and on October 3rd Admiral Penrose hoisted his flag at Plymouth, on board the _Queen_, and left Plymouth on the 8th. Whilst in the Mediterranean, he heard on March 12th, 1815, of the escape of Napoleon from Elba, and of his having reached Prejus. In January, 1816, Admiral Penrose was promoted to the rank of Knight Commander of the Bath. On March 1st he received letters from Lord Exmouth, who appointed a meeting at Port Mahon to proceed against Algiers and Tunis to put an end to the piracies that were carried on from these two places. The squadron sailed for Algiers March 21st. Admiral Penrose wrote: "On arriving at their destination, the ships anchored in two lines out of gun-shot from the batteries, and by signal made all ready for battle; but all went off quietly, and the slaves in whose behalf the expedition was undertaken were ransomed on the terms which Lord Exmouth proposed." From Algiers the squadron sailed for Tunis, and here also the Bey submitted to the demand made on him, and thus ended this impotent expedition. The Bey of Algiers was by no means so overawed that he desisted from his nefarious practices, and a second expedition was sent against him under Lord Exmouth in 1816.
