Tilly, one of the greatest warriors of his time, had first thought of entering the Society, but, on the advice of his spiritual guides, took up the profession of arms. According to Spahn "he displayed genuine piety, remarkable self-control and disinterestedness and seemed like a monk in the garb of a soldier" (The Catholic Encyclopedia, XIV, 724). As he was in command of the league of the Catholic states, and was ordered to restore the lands which had been wrested from their Catholic owners, of course, he gained the reputation of being a bitter foe of Protestantism--an attitude of mind which was attributed to his education at Cologne and Chatelet. Wallenstein, his successor, was educated at the Jesuit college of Olmütz and was a liberal benefactor of his old masters in the work of education. The fact that in 1633 they saved from the fury of a Vienna mob their rancorous enemy, the famous Count de Thurn, when he was taken prisoner by Wallenstein in the Bohemian uprising, ought to count for something in dissipating the delusion that Jesuits are essentially persecutors. When the Emperor Mathias sent them back to Bohemia and founded a college for them at Tirnau and affiliated it to the University of Prague, they showed their gratitude by sacrificing a number of their men in the pestilence which was then raging. Richelieu, who was prominent in what was called the French period of the war, was particularly solicitous in protecting the interests of his former teachers. Although politically supporting the Protestant cause, he invariably stipulated in his treaties that the Jesuits should be protected in the territories handed over to Protestant control, even when they opposed him, as for instance, in the Siege of Prague, where Father George Plachy, a professor of sacred history in the university, led out his students in a sortie and drove back the foe--an exploit which merited for him a mural crown from the city while Emperor Ferdinand III sent an autograph letter to the General of the Society to thank him for the patriotism displayed by Plachy. Indeed, when the Protestant ministers of Charenton wanted Richelieu to suppress the Jesuits, he answered that "it was the glory of the Society to be condemned by those who attack the Church, calumniate the saints, and blaspheme Christ and God. For many reasons, the Jesuits ought to be esteemed by everyone; indeed there are not a few who love them precisely because men like you hate them."
