Ibrahim Pasha, who had taken Acre in 1837, had commenced to strengthen it greatly; but the fortifications he had designed were not completed when the allied squadron of twenty ships, mostly line-of-battle ships, appeared off it, 2nd November 1840. Towed by the steamers, the ships the next morning speedily took up their positions, and opened their fire in the most spirited manner.
After the ships had hotly engaged the batteries for nearly two hours, the grand magazine blew up with a most tremendous explosion, whether caused by a shell or by accident it is difficult to say. A large number of the garrison were blown up, and many probably were buried alive in the ruins or in the casements. The guns, however, notwithstanding this catastrophe, kept up their fire with great spirit to the last. About sunset the signal was made to discontinue the engagement; but the commodore kept the fire up some time after dusk, lest the enemy should be tempted to re-man their guns. The flag-lieutenant then brought the orders to withdraw.
In the middle of the night a small boat brought off the information that the Egyptian troops were leaving the town, and in consequence, at daylight, 300 Turks and a party of Austrian marines landed, and took unopposed possession of the place. The havoc caused by the guns of the squadron on the walls and houses was very great, though, notwithstanding the hot and long-continued fire they had been exposed to, the ships escaped with little damage, and the amount of casualties was very small, being fourteen English and four Turks killed, and forty-two wounded.
An entire battalion, which had been formed near the magazine, ready to resist any attempts to storm, was destroyed. The appearance of the dead and wounded, as they lay scattered about the town, was very dreadful, but they seemed to excite but little sympathy in the breasts of the Turks. Every living creature within the area of 60,000 square yards round the magazine had ceased to exist, the loss of life being computed from 1200 to 2000 persons. Certainly two entire regiments were annihilated, with fifty donkeys, thirty camels, twelve cows, and some horses.
This was the first occasion on which the advantages of steam had been fully proved in battle, by the rapidity with which the steamers took up their positions, and the assistance they rendered to the other ships; as also by the destruction caused through the shells thrown from them.
On the 4th another explosion took place, by which a marine was killed and Captain Collier had his leg fractured.
The garrison being placed in a state of order, was left under the command of Sir Charles Smith, with 3000 Turkish troops and 250 marines, under Lieutenant-Colonel Walker, with the protection of the Pique and Stromboli.
The results of the capture of Acre were very important. Ibrahim Pasha evacuated Syria, and Mehemet Ali gave up the whole Turkish fleet, which sailed for Marmorice under Admiral Walker. Soon after, the Sultan sent a firman, according to the Pasha the hereditary possession of Egypt, without any interference on the part of the Porte, while a yearly tribute of 2,000,000 pounds was to be paid to the Sultan, besides about 2,000,000 pounds more of arrears.
Thus terminated the part taken by the British at that time in the affairs of Turkey and Egypt.
