The full plan of the Armada had now assumed definite form. The King was in possession of Santa Cruz's marvellously complete estimate of cost and requirements of all sorts--a perfect monument of technical knowledge and forethought; the {199} Pope was pledged to find about a third of the necessary funds, and to leave Philip a free hand with regard to the English succession and the time for the carrying out of the enterprise; whilst Philip's position with regard to his claim to the English crown was regularised by Mary's will in his favour. Guise, Beaton, and the Scots had thus been routed all along the line, but it was not to be supposed that they would accept their defeat without a struggle. Their next move was within an ace of being successful, and nearly changed the whole plan of the Armada. In July, 1586, Guise wrote to Mendoza that a plan he had long been concocting had at last been brought to a head, and Beaton was commissioned to tell Mendoza what the scheme was. A Scottish gentleman named Robert Bruce had been sent to France with three blank sheets, signed respectively by Lords Huntly, Morton, and Claude Hamilton, which Guise was to fill up over the signatures with letters to Philip, appealing to him to aid the Scots Catholics. They asked for 6,000 foreign troops for one year and 150,000 crowns to equip their own men, and in return promised to restore Catholicism, release James and his mother, compel the former to become a Catholic, and, most tempting of all, to deliver to Philip one or two good ports near the English Border to be used against the Queen of England. Bruce went to Madrid to lay the Scots' appeal before the King, but when he arrived the failure of the Babington plot and the collapse of the Catholic party in England was known to Philip, and he had lost hope of effecting the "enterprise" except with {200} overwhelming forces of his own. He did not wish, moreover, for Guise's interference, and was coolly sympathetic and no more. And yet, in the face of Santa Cruz's advice that he should secure some ports of refuge for the Armada in the North Sea, the offer of the Scots lords to give him two good Scotch harbours was one not to be lightly refused, so whilst he sent Bruce back with vague promises, he instructed Parma and Mendoza to report fully on the scheme. Parma was cold and irresponsive. He would give no decided opinion until he knew what Philip's intentions were. He was apparently jealous that he was not taken fully into his uncle's confidence, and perhaps angry that his son's claims to the English crown, which were better than those of Philip and his daughter, were being ignored. But Mendoza, an old soldier, the last pupil of Alba, as he called himself, was indignant at Parma's doubts, and wrote to Philip an extremely able paper strongly advising the invasion of England through Scotland, instead of risking everything in a vast fleet, to which one disaster would cripple Spain for ever.
