By his attentive observation of the discipline, manner of battle array, onset of the forces, and the instruction given him in military tactics, he acquired that knowledge of the art of war, for which he afterwards became so distinguished.
At the battle of Peterwaradin, one of the strongest frontier places that Austria had against the Turks, Oglethorpe, though present, was not perhaps actively engaged.

It was fought on the 5th of August, 1716.

The army of the Turks consisted of 150,000 men, of which 40,000 were Janisaries, and 30,000 Saphis, or troopers, the rest were Tartars, Walachians, and the troops of Asia and Egypt.

The army of the Imperialists, under his Serene Highness, Prince Eugene, consisted of but little more than half that number.

The onset began at seven in the morning, and by twelve Eugene was writing to the Emperor an account of the victory in the tent of the Grand Vizier[1].
