_Hungarian_.

Who could be always successful against the early Turk?
He was defeated in the battle in which King Vladislaus lost his life, but his victories outnumbered his defeats three-fold.

His grandest victory--perhaps the grandest ever achieved by man--was over the terrible Mahomed the Second; who, after the taking of Constantinople in 1453, said, "One God in Heaven--one king on earth;" and marched to besiege Belgrade at the head of one hundred and fifty thousand men; swearing, by the beard of the prophet, "that he would sup within it ere two months were elapsed." He brought with him dogs, to eat the bodies of the Christians whom he should take or slay; so says Florentius; hear what he also says: The Turk sat down before the town towards the end of June 1454, covering the Donau and Szava with ships; and on the 4th of July he began to cannonade Belgrade with cannons twenty-five feet long, whose roar could be heard at Szeged, a distance of twenty-four leagues, at which place Hunyadi had assembled his forces.

Hunyadi had been able to raise only fifteen thousand of well-armed and disciplined men, though he had with him vast bands of people, who called themselves Soldiers of the Cross, but who consisted of inexperienced lads from school, peasants, and hermits, armed with swords, slings, and clubs.

Hunyadi, undismayed by the great disparity between his forces and those of the Turk, advanced to relieve Belgrade, and encamped at Szalankemen with his army.
