FIELD MARSHALL, a celebrated general in the Imperial service, born in 1716, was a native of Livonia, and descended from a Scottish family. He made his first campaigns under Marshal Munich, in the war of 1738, between the Russians and Turks; and was at the taking of Oczakow, Choczim, and Stawutzhan, where the Turks were entirely defeated. Frederick the Great refused, in 1741, to take young Laudohn into his service, saying he did not like his countenance; though this monarch, who was considered as the greatest general of his age, afterwards said, that he often admired the positions of other generals, but that he had ever dreaded the battles of Laudohn. In 1756, when but just entered into the service of the house of Austria, with the rank of lieutenant-colonel, he made such a rapid progress, that within less than a year he was a general of artillery, and within three years commander in chief of the whole army. He rescued Olmutz, when besieged by the Prussians; beat the king himself at Frankfort on the Oder; at Zorn-dorf, took General Fourquet prisoner; carried Glatz and Schweidnitz by assault; and stopped the progress of Frederick in a war which might have proved fatal to the house of Austria. In 1778, when elevated to the rank of marshal, at the head of 60,000 men, he hindered Henry, brother to the king of Prussia, from joining his army to that of the king. At Dubicza, Novi, Grandifca, and Belgrade, in the late war between the emperor and the Turks, he had but to present himself before the place, and say with Caesar, Veni, vidi, vici. But at his head quarters in Moravia, he was seized with a fever, in consequence of an operation he underwent for an obstruction in the urethra. His impatience under the medical applications, the impetuous ardour of his character, and the knowledge, above all, of his importance in the war, contributed to irritate his mind, and promote the violence of the fever. He refused the application of cataplasm, before and after the incisions were made, with a fatal obstinacy, which raised the inflammation to such a height, that he expired under the accession of the fever on the 14th of July 1792, in the 74th year of his age.
