For some time the destination of the enormous armament of Philip was not publicly announced. Only Philip himself, the Pope Sixtus, the Duke of Guise, and Philip's favourite minister, Mendoza, at first knew its real object. Rumours were sedulously spread that it was designed to proceed to the Indies to realise vast projects of distant conquest. Sometimes hints were dropped by Philip's ambassadors in foreign courts that his master had resolved on a decisive effort to crush his rebels in the Low Countries. But Elizabeth and her statesmen could not view the gathering of such a storm without feeling the probability of its bursting on their own shores. As early as the spring of 1587 Elizabeth sent Sir Francis Drake to cruise off the Tagus. Drake sailed into the Bay of Cadiz and the Lisbon roads, and burnt much shipping and military stores, causing thereby an important delay in the progress of the Spanish preparations. Drake called this "Singeing the King of Spain's beard." Elizabeth also increased her succours of troops to the Netherlanders, to prevent the Prince of Parma from overwhelming them, and from thence being at full leisure to employ his army against her dominions. Meanwhile in England, from the sovereign on the throne to the peasant in the cottage, all hearts and hands made ready to meet the imminent deadly peril. Circular letters from the queen were sent round to the lord-lieutenants of the several counties requiring them "to call together the best sort of gentlemen under their lieutenancy, and to declare unto them these great preparations and arrogant threatenings, now burst forth in action upon the seas, wherein every man's particular state, in the highest degree, could be touched in respect of country, liberty, wives, children, lands, lives, and (which was specially to be regarded) the profession of the true and sincere religion of Christ; and to lay before them the infinite and unspeakable miseries that would fall out upon any such change, which miseries were evidently seen by the fruits of that hard and cruel government holden in countries not far distant."
