During the Italian campaign Hungary was also called upon to meet another enemy in the East. Roving populations were making constant inroads on the eastern border, harassing the Hungarian inhabitants, who had by this time become accustomed to the peaceful avocations of the husbandman and tradesman. The victorious arms of King Louis soon put an end to those lawless incursions. But one of the most beautiful legends of Hungarian history is connected with one of the campaigns against these marauding populations. Kieystut, the Prince of Lithuania, after having been defeated several years before, broke into Transylvania with an army considerably swelled by the accession of a numerous body of Tartars. The king sent Louis Laczfy, the vayvode of Transylvania, against him, and the brave Székely people followed in his train. But the Hungarian army was small and the issue of the battle remained for a long time doubtful. The legend tells that the news of the peril threatening the Hungarian arms reached Grosswardein, where St. Ladislaus lay buried, and that the heroic saint, leaving his grave, bestrode the bronze horse of his own statue, which stood in the centre of the public square, and hurried off to the relief of his distressed countrymen. The Tartars were struck with the apparition of a warrior “who towered over them head and shoulders,” and above whom was visible the holy Virgin Mary, the patroness of Hungary. The pagans were seized with terror at this sight, and the battle ended in a brilliant victory for the Hungarians.
