From the Bay of Marmorice the fleet sailed on the 23rd of February, and the greatness of the armament, with the gaiety of the brave men on board, was calculated to excite a deep feeling of interest respecting the destiny of the expedition, which involved the dearest interests of Great Britain. The gallant troops employed on this enterprise proved worthy of the confidence reposed in them, and they more than realized the expectations of their king and country. Arriving off the celebrated city of Alexandria in the beginning of March, the fleet bore down into the Bay of Aboukir, and on the 8th of that month, the troops landed, and defeated a numerous body of cavalry, infantry, and artillery, formed to oppose them. Advancing towards _Alexandria_, the army encamped, on the 12th of March, near Mandora Tower, and on the following day marched through a grove of date-trees, and drove the enemy from a position he occupied. The TWELFTH Light Dragoons had one man and four horses killed; one serjeant, and one private soldier wounded. After this success the army encamped, and the Egyptian peasantry brought a supply of sheep, goats, poultry, and eggs. On the 18th of March, when a great part of the regiment had left the camp to water the horses, information arrived of the approach of a reconnoitring party, and Lieut.-Colonel Archdall collected sixty men, with whom he advanced to meet the enemy, taking also a piquet of twenty men. After proceeding about three miles, he met one hundred and fifty French hussars and infantry, under General D'Estin, and, notwithstanding the disparity of numbers, he instantly detached Lieutenant Levingston with twelve men to attack the left flank of the French hussars, while he charged the front with the main body. Dashing furiously upon his opponents, Colonel Archdall broke the French infantry at the first onset; their cavalry instantly fled, and the British troopers pursued, killing and wounding several, but the main body of the French hussars, being better mounted than the British, escaped. The precaution of securing the French infantry had been, inconsiderately, omitted, and when the troopers returned from the pursuit, they were fired upon by the foot from behind a sandhill, which occasioned some loss, and, finally, the French infantry effected their retreat. The TWELFTH Light Dragoons had five horses killed; Lieut.-Colonel Archdall, and one serjeant wounded; Captain the Honorable Pierce Butler, Cornet Earle Lindsay Daniel, and seven men, who had been most eager in the pursuit, were intercepted in their return, and made prisoners. Lieut.-Colonel Archdall lost his arm, and the command of the TWELFTH Dragoons devolved on Lieut.-Colonel Robert Browne. On the 21st of March the British repulsed an attack of the French on their position; but they had to lament the loss of Sir Ralph Abercromby, who was mortally wounded. The loss of the TWELFTH Light Dragoons was limited to seven men wounded.
