Don Antonio, of Portugal, having advanced a claim to the crown of that country, then held by Spain, an expedition was undertaken, in England, to conquer that country for him. Nearly 20,000 volunteers enlisted, and ships were hired and arms and provisions provided by the adventurers. The frugal Queen only contributed to the enterprise some £60,000 and six of her ships. Sir Francis Drake and Sir John Norris were at the head of it, and if they had not allowed themselves to be drawn off from the main object of their enterprise to attack a Spanish fleet, fitting at the Groyne for another invasion of England, it is quite probable that Lisbon would have been taken by a _coup-de-main_. In consequence of their delay Lisbon was too strongly defended, and the English fleet was obliged to retire. After taking and burning Vigo they returned to England, having lost more than half their number by sickness, famine, fatigue, and wounds. This was, indeed, usually the case with the maritime adventurers of that day, the losses from illness alone being perfectly frightful. As this expedition was returning another was going out, under the Earl of Cumberland, all the ships, except one man-of-war sent by the Queen, being equipped at his own expense. Cumberland went to the Terceras and took many Spanish prizes, but the richest one, a galleon, was lost on the Cornish coast, in the attempt to reach England. Attempting to seize the Islands, Cumberland met with a bloody repulse, losing nearly half his men, and a great mortality seizing upon the survivors, left him hardly men enough to steer his ships back into a home harbor. But all these maritime expeditions, whether successful or not, had a good effect in keeping the Spaniards in check, as well as in keeping up the spirit and nautical ability of the English. At a later period, when Elizabeth was assisting Henri Quatre, in France, against the Duke of Parma and the League, she employed her naval power very freely against Philip, and endeavored at all times to intercept his West Indian treasure ships, the source of that greatness which rendered him so formidable to all his neighbors. Among other operations she sent Lord Thomas Howard, with a squadron of seven ships, upon this service. But Philip, informed of her intentions, fitted out a great fleet of fifty-five sail, and despatched them to escort home the fleet of galleons from the West Indies.
