After this there were rumors of peace for these tormented countries; but the Turks, who did not yet appreciate the nature of this force, called John Smith, that had come into the world against them, did not intend peace, but went on levying soldiers and launching them into Hungary. To oppose these fresh invasions, Rudolph II., aided by the Christian princes, organized three armies: one led by the Archduke Mathias and his lieutenant, Duke Mercury, to defend Low Hungary; the second led by Ferdinand, the Archduke of Styria, and the Duke of Mantua, his lieutenant, to regain Caniza; the third by Gonzago, Governor of High Hungary, to join with Georgio Busca, to make an absolute conquest of Transylvania.
In pursuance of this plan, Duke Mercury, with an army of thirty thousand, whereof nearly ten thousand were French, besieged Stowell-Weisenberg, otherwise called Alba Regalis, a place so strong by art and nature that it was thought impregnable.
This stronghold, situated on the northeast of the Platen Sea, was, like Caniza and Oberlympack, one of the Turkish advanced posts, by means of which they pushed forward their operations from Buda on the Danube.
This noble friend of Smith, the Duke of Mercury, whom Haylyn styles Duke Mercurio, seems to have puzzled the biographers of Smith. In fact, the name of “Mercury” has given a mythological air to Smith’s narration and aided to transfer it to the region of romance. He was, however, as we have seen, identical with a historical character of some importance, for the services he rendered to the Church of Rome, and a commander of some considerable skill. He is no other than Philip de Lorraine, Duc de Mercceur.’
[So far as I know, Dr. Edward Eggleston was the first to identify him. There is a sketch of him in the “Biographie Universelle,” and a life with an account of his exploits in Hungary, entitled: Histoire de Duc Mercoeur, par Bruseles de Montplain Champs, Cologne, 1689-97]
At the siege of Alba Regalis, the Turks gained several successes by night sallies, and, as usual, it was not till Smith came to the front with one of his ingenious devices that the fortune of war changed. The Earl Meldritch, in whose regiment Smith served, having heard from some Christians who escaped from the town at what place there were the greatest assemblies and throngs of people in the city, caused Captain Smith to put in practice his “fiery dragons.” These instruments of destruction are carefully described: “Having prepared fortie or fiftie round-bellied earthen pots, and filled them with hand Gunpowder, then covered them with Pitch, mingled with Brimstone and Turpentine, and quartering as many Musket-bullets, that hung together but only at the center of the division, stucke them round in the mixture about the pots, and covered them againe with the same mixture, over that a strong sear-cloth, then over all a goode thicknesse of Towze-match, well tempered with oyle of Linseed, Campheer, and powder of Brimstone, these he fitly placed in slings, graduated so neere as they could to the places of these assemblies.”
