In 1799 he was selected to command the first division of the Anglo-Russian army destined to attempt the deliverance of Holland from the power of France; and in effecting a landing on the 27th of August,--in repulsing the troops assembled to oppose him,--and in gaining possession of the forts of the Helder, which was followed by the surrender of the Dutch fleet, he evinced the abilities of a consummate general and the valour of a hero. He was also successful in the action of the Zyp on the 10th of September. After the arrival of the Duke of York he commanded a division under His Royal Highness with reputation; and in the accounts of the engagements which followed, his conduct was mentioned in terms of the highest praise. After his return from Holland he was appointed to the command of an expedition sent into the Mediterranean. He captured Malta, and appeared before Cadiz; but an epidemic disease raging in the city at the time, the attempt on this fortress was desisted in for fear of infection. He subsequently directed his course towards Egypt, with the view of driving the French army from that country; and while the fleet anchored in the bay of Marmorice, in Asiatic Turkey, he arranged a plan of co-operation with the Turks. In February, 1801, he again put to sea, and on the 8th of March he effected a landing in the bay of Aboukir, and defeated a body of French troops. On the 13th he drove the French from their position beyond Mandora Tower, on which occasion he had a horse shot under him; and on the 19th Fort Aboukir capitulated. On the 21st of the same month he repulsed a furious attack of the enemy on the position which he occupied near Alexandria, and during the action he received a mortal wound which deprived his king and country of his most valuable services. He appears to have been wounded in the early part of the day, but continued in the field giving his orders with that coolness and perspicuity which had ever marked his character, till after the action was over, when he fainted through weakness and loss of blood, and died on the 28th of March, 1801.
