At the same time that Escovedo was escaping so wonderfully from these three attempts on his life, tidings arrived at Madrid, which had been always feared and expected, and which came to change entirely Philip II's plans and policy. War, more cruel and gory than ever, had broken out in Flanders, provoked by the rebels. D. John, having received a handful of money to animate his German troops, and joining them to some Spanish soldiers who had returned to France, and who, knowing his danger, spontaneously flew to his aid, at Gembleux gloriously picked up the glove that the rebels threw down, and gained over them that marvellous victory which placed his personal courage in as much relief as it did his talent as a leader, his prophetic political sagacity, and his real faith as a Christian. "With this sign I vanquished the Turks; with this sign I will vanquish the heretics," he had written round the cross on his standard; and to his friends D. Diego de Mendoza and the Conde de Orgaz he communicated the great news that his losses only consisted of four killed and fifteen wounded, the enemy having been 5000, adding humbly, "God did it, and His only was the day, at a time, when if it had not been done, we should have died of hunger, surrounded by a hundred thousand other dangers."
The Baron de Willy, dispatched by D. John after the battle which was fought on the 31st of January, 1578, brought the news to Philip. He also informed him of the dreadful state of unrest in these provinces, all in open rebellion, where religion was not respected, nor the King obeyed, nor any Catholic law venerated. The fortresses gave their troops, the cities, towns and even the miserable villages armed their militia, and all joined in pursuing D. John, then deprived of all aid, surrounding him, pressing him, destroying and overthrowing at the same time the strong leader and the hated Spanish yoke. The victory of Gembleux, gained by D. John, made them retire and widen the circle, like cowardly hounds who see the lion they imagined done for suddenly rise, with bristling mane and outstretched claws. Many of them never stopped until they reached Brussels, and from there some fled to Antwerp, where they imagined themselves safe. But, once they had recovered from their surprise and fright, and knew that there was abundance of nothing except valour in D. John's camp, they would return to reunite, and once again narrow the circle, advancing slowly and with great caution, until at last they would fall on D. John and annihilate him by their numbers, if the help asked for in his letters were not sent. In these letters, which the Baron de Willy gave to Philip, D. John paints a vivid picture of his situation, and asks more urgently than ever for soldiers and plenty of money. He also begs that his secretary Escovedo may be sent, in the utmost good faith and ignorance of what was happening, recommending him warmly to his brother D. Philip for certain favours, which D. John averred he very well deserved.
All these facts and circumstances brought two things, distinct but much connected with each other, to the knowledge of Philip; one, that it was high time to give up his exaggerated peace policy in Flanders and take refuge in that of force, as his brother had been urging him for months. The other, that once the war had been lighted in Flanders by the rebels the danger of Escovedo doing so had ceased, and consequently also the political reason which made Philip condemn him to death. It was hard for Philip to make practical use of these two convictions, because by the first he had to retract an opinion he had held long and tenaciously; and by the second he had to smother grudges, dislikes and petty spites, which, united, made up what he, wrongly but sincerely, conceived to be political reasons, and which had undeniably influenced him in sentencing Escovedo to death. But the iron will of the prudent King knew how to drown personal feelings, and hide at any rate dislikes and spites, and frankly and definitely to enter on another course. So he wrote to D. John by the Baron de Willy: "If before he had been tardy in not making war on the rebels, to give them time to quiet themselves, as his clemency had done nothing but irritate them, he desired to sustain his authority by arms, and in order that it could be done in his name, he sent 900,000 crowns, offering to provide in future 200,000 each month, with which D. John was to maintain an army of 30,000 infantry and 6500 horse, without any prejudice to everything he thinks should be granted."
He also sent a fresh edict, which he ordered to be published, in which, after enumerating the offences of the rebels again............
