Philip had been advised, in the first instance, to effect a landing and secure a strong position in Ireland; his admiral, Santa Cruz, had recommended him to make sure, in the first instance, of some large harbour on the coast of Holland or Zealand, where the Armada, having entered the Channel, might find shelter in case of storm, and whence it could sail without difficulty for England; but Philip rejected both these counsels, and directed that England itself should be made the immediate object of attack; and on May 20th the Armada left the Tagus, in the pomp and pride of supposed invincibility, and amidst the shouts of thousands, who believed that England was already conquered. But steering to the northward, and before it was clear of the coast of Spain, the Armada was assailed by a violent storm, and driven back with considerable damage to the ports of Biscay and Galicia. It had, however, sustained its heaviest loss before it left the Tagus, in the death of the veteran admiral Santa Cruz, who had been destined to guide it against England. Philip II. had replaced him by Alonzo Perez de Gusman, Duke of Medina Sidonia, one of the most powerful of the Spanish grandees, but wholly unqualified to command such an expedition. He had, however, as his lieutenants, two seamen of proved skill and bravery, Juan de Martinez Recalde of Biscay, and Miguel Orquendo of Guipuzcoa. On July 12th, the Armada having completely refitted, sailed again for the Channel, and reached it without obstruction or observation by the English. The orders of King Philip to the Duke de Medina Sidonia were, that he should, on entering the Channel, keep near the French coast, and, if attacked by the English ships, avoid an action, and steer on to Calais roads, where the Prince of Parma's squadron was to join him. The hope of surprising and destroying the English fleet in Plymouth led the Spanish admiral to deviate from these orders, and to stand across to the English shore; but, on finding that Lord Howard was coming out to meet him, he resumed the original plan, and determined to bend his way steadily towards Calais and Dunkirk, and to keep merely on the defensive against such squadrons of the English as might come up with him.
