The eventual naval victory of England was preceded by a long course of successful diplomacy. As the aggressor England forced the haughtiest power in Europe to endure a protracted series of outrages. Not only were rebels supported, not only were Spanish fleets taken forcibly into English harbors and there stripped of moneys belonging to their government, but refugees were protected and Spanish citizens put to death by the English queen. Philip and Alva could not effectively resent and hardly dared to protest against the treatment, because they felt themselves powerless. As so often, the island kingdom was protected by the ocean and by the proved superiority of her seamen. After a score of petty fights all the way from the Bay of Biscay to the Pacific Ocean, Spanish sailors had no desire for a trial of strength in force. But in every respect save in sea power Spain felt herself immeasurably superior to her foe. Her wealth, her dominions, recently augmented by the annexation of Portugal, were enormous; her army had been tried in a hundred battles. England's force was doubtless underestimated. An Italian expert stated that an army of 10,000 to 12,000 foot and 2,000 horse would be sufficient to conquer her. Even to the last it was thought that an invader would be welcomed by a large part of the population, for English refugees never wearied of picturing the hatred of the people for their queen. But the decision was long postponed for two reasons. First, Spain was fully employed in subduing the Netherlands. Secondly, the Catholic powers hoped for the accession of Mary. But after the assassination of Orange in 1584, and after the execution of the Queen {341} of Scots, these reasons for delay no longer existed. Drake carried the naval war [Sidenote: 1585] to the coasts of Spain and to her colonies. The consequent bankruptcy of the Bank of Seville and the wounded national pride brought home to Spaniards the humiliation of their position. All that Philip could do was to pray for help and to forbid the importation of English wares. [Sidenote: April 1587] In reply Drake fell upon the harbor of Cadiz and destroyed twenty-four or more warships and vast military stores. So at last the decision was taken to crush the one power that seemed to maintain the Reformation, to uphold the Huguenots and the Dutch patriots and to harry with impunity the champions of Catholicism. Pope Sixtus V, not wishing to hazard anything, promised a subsidy of 1,000,000 crowns of gold, the first half payable on the landing of the Spanish army, the second half two months later. Save this, Philip had no promise of help from any Catholic power.
