The fleets were nearly equal in strength, and their relative merits had to be determined on that day. Even the common seamen on each side felt that this was the decisive battle.

At the outset the Dutch had the wind, and therefore, the advantage of position. They were also well up together, and when they opened on the English vanguard it seemed almost impossible for only about twenty ships to withstand the crash of so many heavy broadsides.

As usual, the Triumph was the first of the English to engage, and the Brederode, ever in the van, was ready to meet her, reserving her fire until within musket shot, when her broadside would have most deadly effect. With a strong favoring breeze Tromp shot by the Triumph, pouring a fearful broadside into her as he passed; and then, tacking, gave her a second and more destructive one, leaving her with decks strewed with killed and wounded, and torn canvas, stranded rigging, and tottering masts. After this the two Admirals parted for the day, for Penn came dashing up, in the Speaker, followed by other vessels, to cover Blake from some part of the circle of fire which threatened him with destruction.

As the other divisions of the English fleet came up the battle became general. On both sides the wreck and destruction was awful. In less than one hour after the first shot was fired almost every ship engaged had received serious damage. At one moment an English crew was to be seen boarding a Dutch man-of-war, and the next they would be driven back, and their own vessel boarded in turn by the doughty Hollanders. Here might be seen a ship completely wrapped in flames; there one foundering, with all her men, their cries for help unheeded by either friend or foe; perhaps elsewhere occurred a fearful explosion, which sent ship and crew into the air together, and added fresh volume to the lurid cloud which hung over the scene.

Cotemporary writers say that the tremendous roar of artillery could be heard along the shores of the Channel, from Boulogne on the one side to Portland Bill on the other.

About midday Monk succeeded in arriving up with his division, and the contest was now entirely upon equal terms. De Ruyter, as ever, in the forefront of battle, added, if possible, to his already well earned renown. Early in the day he singled out and engaged the Prosperous, a hired ship of forty guns, commanded by a Captain Barker. The English ship maintained so steady a fire, in response, that De Ruyter, impatient, and wishing to finish her and pass on to fresh combats, called away his boarders, ran his ship alongside the Prosperous, and the Dutchmen gallantly boarded, leaping down on her deck, sword and pistol in hand. But, to their surprise, they were driven back again in a very few minutes. Not satisfied with forcing back his assailants, Barker threatened De Ruyter in return; but the brave old Dutchman, singing out, “Come lads! that was nothing! at them again!” led them to a second and more successful boarding. Barker and his officers were unable to resist this renewed assault, and were soon prisoners. At this very moment Blake, with several vessels, came up to their assistance. The prize was recovered, and Ruyter himself was surrounded by the English. Vice Admiral Evertz and Captains Swers and Krink hastened, in their turn, to relieve Ruyter from his dangerous position, and the battle soon raged with extraordinary violence around this new centre. Penn’s ship, the Speaker, was so shattered as to be unfit for further service, and when night put an end to the first day’s engagement he was despatched to the Isle of Wight, for the ships left at that station.

The Dutch Captain Cruik, in the Ostrich, was very conspicuous in this day’s engagement. Like a true sailor, he fought till he had not a spar showing above his bulwarks, and his deck was literally covered with the dead and wounded of his devoted crew. At last he was boarded by the English; but, as the ship appeared to be sinking, and her officers and crew were nearly all killed or wounded, the boarders made hasty plunder of her valuables and left her to her fate. De Wilde offered his aid to bring her off; but suddenly it fell calm, and not having a particle of sail spread, the attempt to tow her off failed, and she was again abandoned. Next morning Blake found her floating about, without a living soul on board, and the unburied corpses lying just as they had fallen; occasionally, under a more than ordinarily heavy roll, showing a startling movement.

Captain Swers, afterward a most distinguished Dutch Admiral, was taken prisoner. He had gone to the assistance of Captain De Port, who was being roughly handled by two English frigates, and the four ships were immediately locked together. De Port’s ship had several shots between wind and water, and began to fill. He himself was severely wounded by a large splinter; nevertheless, as he lay on his back, in great agony, he waved his sword, and shouted words of encouragement to his men, until ship and crew all went down into the deep together.

The Dutch had always been noted for close fire, but on this occasion the English fire proved quite as deadly and regular. Swer’s ship foundered from shot holes, himself and those of the officers and crew left being taken on board the frigates, and their lives thus preserved.

Toward dusk of the second day Blake felt himself in a sufficiently strong position to be able to send some of his best sailing ships with orders to gain the wind, and if possible prevent the escape of the vast fleet of rich traders which had remained hove to, awaiting the issue of the action. Tromp saw the movement, and at once divined the cause, so he fell back, with a great part of his fleet, to cover his convoy. This movement put an end to that day’s action; for, seeing their Admiral make sail and leave the enemy, some of the Dutch Captains made sail, and, under the cover of night, were soon far away. Blake remained on the scene of action, but with his men too much exhausted, and his vessels too much damaged, to permit of a chase in a mid-winter night.
