But his genius, which prompted him to the greatest undertakings, engaged him to quit his father's house at the age of fourteen; and he served four months[31] in quality of a cadet in the citadel of Marseilles; from thence he went to Holland, where he served some time as a volunteer, and was wounded at the siege of Grave, a strong fortified town on the Meuse, which the prince of Orange, afterwards king of England, retook from Lewis XIV. in 1674. After this, led by hopes of preferment, wherever he could find it, he embarked with a German colonel, named Verstin, who had obtained a commission from Peter's father, the czar Alexis, to raise soldiers in the Netherlands, and bring them to Archangel. But, when he arrived at that port, after a most fatiguing and dangerous navigation, the czar Alexis was no more; the government was changed, and Russia in confusion. The governor of Archangel suffered Verstin, Le Fort, and his whole troop, to remain a long time, in the utmost poverty and distress, and even threatened to send them into the extremity of Siberia; upon which every man shifted for himself. Le Fort, in want of every thing, repaired to Moscow, where he waited upon the Danish resident, named De Horn, who made him his secretary: there he learned the Russian language, and some time afterwards found means to be introduced to the czar Peter; the elder brother, Iwan, not being a person for his purpose. Peter was taken with him, and immediately gave him a company of foot. Le Fort had seen very little service, he knew but little of letters, not having studied any particular art or science; but he had seen a great deal, and had a talent of making the most of what he saw. Like the czar, he owed every thing to his own genius; he understood the German and Dutch languages, which Peter was learning, as those of two nations that might be of service in his designs. Every thing conspired to make him agreeable to Peter, to whom he strictly attached himself. From being the companion of his pleasures, he became his favourite, and confirmed himself in that station by his abilities. The czar made him his confidant in the most dangerous design that a prince of that country could possibly form, namely, that of putting himself in a condition to be able one day to break the seditious and barbarous body of forces called the strelitzes. It had cost the great sultan or basha Osman his life, for attempting to disband the janissaries. Peter, young as he was, went to work in a much abler manner than Osman.
