How to meet and repel this immense danger caused many consultations on the part of Elizabeth and her statesmen, and at first they inclined to make the defence by land only. But Raleigh, like Themistocles at Athens under similar conditions, urgently advised dependence on a well-equipped fleet, and after some hesitation his advice was followed. Then every effort was strained to bring into service every ship that could be found or constructed in time within the limits of England, so that in May, 1588, when Philip's huge Armada set sail from the Tagus, a numerous English fleet was ready to dispute its onward passage. A great battle was fought soon after in the English Channel, and there Lord Charles Howard of Effingham, and Raleigh and Drake and Hawkins joined with Grenville and Cavendish and Frobisher and Lane, and all the other glorious heroes of England, in the mighty overthrow of the Spanish enemy.[18] Under the inspiration of this tremendous victory the Atlantic Ocean during the next three years swarmed with English cruisers, and more than eight hundred Spanish ships fell victims to their attacks. So great was the destruction that the coast of Virginia abounded in the wreckage.[19] But the way to a successful settlement in America was not entirely opened until eight years later, when the English fleet, under Howard, Raleigh, and Essex, completed the destruction of the Spanish power by another great naval victory won in the harbor of Cadiz. Amid all this excitement and danger Raleigh did not forget his colony in Virginia. Twice he sent relief expeditions; but the first was stopped because in the struggle with Spain all the ships were demanded for government service; and the second was so badly damaged by the Spanish cruisers that it could not continue its voyage. Raleigh had spent L40,000 in his several efforts to colonize Virginia, and the burden became too heavy for him to carry alone. As Hakluyt said, "It required a prince's purse to have the action thoroughly followed out." He therefore consented, in 1589, to assign a right to trade in Virginia to Sir Thomas Smith, John White, Richard Hakluyt, and others, reserving a fifth of all the gold and silver extracted, and they raised means for White's last voyage to Virginia.[20]
