The Prince of Parma, who was appointed military chief of the expedition, collected on the coast of Flanders a veteran force that was to play a principal part in the conquest of England. Besides the troops who were in his garrisons, or under his colours, five thousand infantry were sent to him from northern and central Italy, four thousand from the kingdom of Naples, six thousand from Castile, three thousand from Arragon, three thousand from Austria and Germany, together with four squadrons of heavy-armed horse; besides which he received forces from the Franche-Comté and the Walloon country. By his command, the forest of Waes was felled for the purpose of building flat-bottomed boats, which, floating down the rivers and canals to Meinport and Dunkerque, were to carry this large army of chosen troops to the mouth of the Thames, under the escort of the great Spanish fleet. Gun-carriages, fascines, machines used in sieges, together with every material requisite for building bridges, forming camps, and raising fortresses, were to be placed on board the flotillas of the Prince of Parma, who followed up the conquest of the Netherlands whilst he was making preparations for the invasion of this island. His intention was to leave to the Count de Mansfeldt sufficient forces to follow up the war with the Dutch, which had now become a secondary object, whilst he himself went at the head of fifty thousand men of the Armada and the flotilla, to accomplish the principal enterprise--that enterprise, which, in the highest degree, affected the interests of the pontifical authority. In a bull, intended to be kept secret until the day of landing, Sixtus V., renewing the anathema fulminated against Elizabeth by Pius V. and Gregory XIII., affected to depose her from our throne. Elizabeth was denounced as a murderous heretic whose destruction was an instant duty. A formal treaty was concluded (in June, 1587), by which the pope bound himself to contribute a million of scudi to the expenses of the war; the money to be paid as soon as the king had actual possession of an English port. Philip, on his part, strained the resources of his vast empire to the utmost. The French Catholic chiefs eagerly co-operated with him. In the sea-ports of the Mediterranean, and along almost the whole coast from Gibraltar to Jutland, the preparations for the great armament were urged forward with all the earnestness of religious zeal, as well as of angry ambition.
