England was watching the struggle of Henry the Fourth with a keen interest. The failure of the expedition against Lisbon had put an end for the time to any direct attacks upon Spain, and the exhaustion of the treasury forced Elizabeth to content herself with issuing commissions to volunteers. But the war was a national one, and the nation waged it for itself. Merchants, gentlemen, nobles fitted out privateers. The sea-dogs in ever-growing numbers scoured the Spanish Main. Their quest had its ill chances as it had its good, and sometimes the prizes made were far from paying for the cost of the venture. "Paul might plant, and Apollos might water," John Hawkins explained after an unsuccessful voyage, "but it is God only that giveth the increase!" But more often the profit was enormous. Spanish galleons, Spanish merchant-ships, were brought month after month to English harbours. The daring of the English seamen faced any odds. Ten English trading vessels beat off twelve Spanish war-galleys in the Straits of Gibraltar. Sir Richard Grenville in a single bark, the Revenge, found himself girt in by fifty men-of-war, each twice as large as his own. He held out from afternoon to the following daybreak, beating off attempt after attempt to board him; and it was not till his powder was spent, more than half his crew killed, and the rest wounded, that the ship struck its flag. Grenville had refused to surrender, and was carried mortally wounded to die in a Spanish ship. "Here die I, Richard Grenville," were his last words, "with a joyful and a quiet mind, for that I have ended my life as a good soldier ought to do, who has fought for his country and his queen, for honour and religion." But the drift of the French war soon forced Elizabeth back again into the strife. In each of the French provinces the civil war went on: and in Britanny, where the contest raged fiercest, Philip sent the Leaguers a supply of Spanish troops. Normandy was already in Catholic hands, and the aim of the Spanish king was to secure the western coast for future operations against England. Elizabeth pressed Henry the Fourth to foil these projects, and in the winter of 1591 she sent money and men to aid him in the siege of Rouen. [Sidenote: Henry's conversion.]
