From his wonderful courage and determination never to fly from an enemy, however great the odds might be against him, he had the good fortune to win glory in the most glorious sea-fight that has ever been fought.

In 1591 he was vice-admiral of a small fleet consisting of six line of battle ships, six victuallers, and two or three pinnaces, under the command of Lord Thomas Howard. In the month of August in that year, they lay at anchor off the island of Flores, where they had put in for a fresh supply of water, and to take in ballast, as well as to refresh the crew, for many of them were sick.

Half of the crew of Grenville's ship were disabled and were on shore, when news was brought that a Spanish Armada, consisting of fifty-three ships, was near at hand.

When the admiral heard it, knowing himself to be at a disadvantage, he instantly signalled to the rest of the fleet to cut or weigh their anchors and to follow him out to sea.

All the commanders obeyed his summons but Sir Richard Grenville, whose duty as vice-admiral was to follow at the rear of the fleet; he also waited until his men who were on shore could rejoin him.

Meanwhile he had everything set in readiness to fight, and all the sick were carried to the lower hold.

The rest of the English ships were far away, hull down on the horizon, and the Spaniards, who had come up under cover of the island, were already bearing down in two divisions on his weatherbow before the 'Revenge' was ready to sail. Then the master and others, seeing the hopelessness of their case, begged Sir Richard to trust to the good sailing of his ship, 'to cut his maine saile and cast about, and to follow the admiral.'

But Sir Richard flew into a terrible passion, and swore he would hang any man who should then show himself to be a coward. 'That he would rather choose to dye than to dishonour himselfe, his countrie, and her maiestie's shippe.'

He boldly told his men that he feared no enemy, that he would yet pass through the squadron and force them to give him way.

Then were the hundred men on the 'Revenge' who were able to fight and to work the ship, fired with the spirit of their commander, and they sailed out to meet the foe with a cheer.

All went well for a little time, and the 'Revenge' poured a broadside into those ships of the enemy that she passed. But presently a great ship named 'San Felipe' loomed over her path and took the wind out of her sails, so that she could no longer answer to her helm.

While she lay thus helplessly, all her sails of a sudden slack and sweeping the yards, she fired her lower tier, charged with crossbar shot, into the 'San Felipe.' Then the unwieldy galleon of a thousand and five hundred tons, which bristled with cannon from stem to stern, had good reason to repent her of her temerity, and 'shifted herselfe with all dilligence from her sides, utterly misliking her entertainment.' It is said she foundered shortly afterwards.

Meanwhile four more Spanish vessels had come up alongside the 'Revenge,' and lay two on her larboard and two on her starboard. Then a hand to hand fight began in terrible earnest. As those soldiers in the ships alongside were repulsed or thrown back into the sea, yet were their places filled with more men from the galleons around, who brought fresh ammunition and arms. The Spanish ships were filled with soldiers, in some were two hundred besides mariners, in some five hundred, in others eight hundred.

'And a dozen times we shook 'em off as a dog that shakes his ears when he leaps from the water to the land.'

Grenville was severely hurt at the beginning of the fight, but he paid no heed to his wound, and stayed on the upper decks to cheer and encourage his men. Two of the Spanish ships were sunk by his side, yet two more came in their places, and ever and ever more as their need might be.

Darkness fell upon the scene, and through the silence the musketry fire crackled unceasingly, and the heavy artillery boomed from time to time across the sea. About an hour before midnight Grenville was shot in the body, and while his wound was being dressed, the surgeon who attended him was killed, and at the same time Grenville was shot again in the head.

Still he cried to his men, 'Fight on, fight on!'

Before dawn the Spaniards, weary of the fight that had raged for fifteen hours, that had cost them fifteen ships and fifteen hundred men, had drawn off to a little distance, and lay around her in a ring.

Daylight discovered the little 'Revenge' a mere water-logged hulk, with rigging and tackle shot away, her masts overboard, her upper works riddled, her pikes broken, all her powder spent, and forty of her best men slain.

The glow that heralded sunrise shot over the sky and stained the placid waters beneath to crimson. In this sea of blood the wreck lay, her decks ruddy with the stain of blood sacrificed for honour.

She lay alone at the mercy of the waves, and unable to move save by their rise and fall, alone with her wounded and dying and her dead to whom could come no help.

Then Sir Richard Grenville called for the master gunner, whom he knew to be both brave and trusty, and told him to sink the ship, so that the Spaniards might have no glory in their conquest. He besought his sailors to trust themselves to the mercy of God, and not to the mercy of men, telling them that for the honour of their country the greater glory would be theirs if they would consent to die with him.

The gunner and many others cried, 'Ay, ay, sir,' and consented to the sinking of the ship.

But the captain and master would not agree to it: they told Sir Richard that the Spanish admiral would be glad to listen to a composition, as themselves were willing to do. Moreover there were still some men left who were not mortally wounded, and who might yet live to do their country good service. They told him too that the Spaniard could never glory in having taken the ship, for she had six feet of water in the hold already, as well as three leaks from shot under water, that could not be stopped to resist a heavy sea.

But Sir Richard would not listen to any of their reasoning. Meanwhile the master had gone to the general of the Armada, Don Alfonso Baffan, who, knowing Grenville's determination to fight to the last, was afraid to send any of his men on board the 'Revenge' again, lest they should be blown up or sink on board of her.

The general yielded that 'all their lives should be saved, the companie sent for England, and the better sorte to pay such reasonable ransome as their estate would beare, and in the meane season to be free from galley or imprisonment.'

After the men had heard what the captain said they became unwilling to die, and with these honourable terms for surrender they drew back from Sir Richard and the master gunner. 'The maister gunner, finding himselfe prevented and maistered by the greater number, would have slaine himselfe with a sword had he not beene by force withhold and locked into his cabben.'

Then the Spanish general sent to the 'Revenge' to bring Sir Richard to his own ship; for he greatly admired his wonderful courage.

Sir Richard told him they might do what they chose with his body, for he did not care for it; and as he was being carried from his ship in a fainting state, he asked those of his men near him to pray for him.

He only lived for three days after this, but was treated with the greatest courtesy and kindness by the Spaniards. He did not speak again until he was dying, when he said:

'Here am I, Richard Grenville, with a joyful and quiet mind, for that I have ended my life as a true soldier ought to do, that hath fought for his country, Queen, religion, and honour. Whereby my soul most joyfully departeth out of this body, and shall always leave behind it an everlasting fame of a valiant and true soldier, that hath done his dutie as he was bound to do.'
