The design of the Spaniards was, that the Armada should give them, at least for a time, the command of the sea, and that it should join the squadron which Parma had collected, off Calais. Then, escorted by an overpowering naval force, Parma and his army were to embark in their flotilla, and cross the sea to England where they were to be landed, together with the troops which the Armada brought from the ports of Spain. The scheme was not dissimilar to one formed against England a little more than two centuries afterwards. As Napoleon, in 1805, waited with his army and flotilla at Boulogne, looking for Villeneuve to drive away the English cruisers, and secure him a passage across the Channel, so Parma, in 1588, waited for Medina Sidonia to drive away the Dutch and English squadrons that watched his flotilla, and to enable his veterans to cross the sea to the land that they were to conquer. Thanks to Providence, in each case England's enemy waited in vain! Although the numbers of sail which the queen's government, and the patriotic zeal of volunteers, had collected for the defence of England exceeded the number of sail in the Spanish fleet, the English ships were, collectively, far inferior in size to their adversaries; their aggregate tonnage being less by half than that of the enemy. In the number of guns, and weight of metal, the disproportion was still greater. The English admiral was also obliged to subdivide his force; and Lord Henry Seymour, with forty of the best Dutch and English ships, was employed in blockading the hostile ports in Flanders, and in preventing the Prince of Parma from coming out of Dunkirk. 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.
