14:00. Russell, driving northwards to join the attack, encountered the now extinguished Hercules, whose crew had thrown all of their ammunition overboard during the fire to prevent the ship exploding. The ship was thus defenceless, Commander Ruijsoort surrendering immediately. The remainder of the British fleet now arrived in the battle, Captain John Wells of HMS Lancaster firing on the Beschermer near the head of the Dutch line. Aware that their vessel would be unable to resist the attack, Beschermer 's surviving officers turned away towards the shore, rapidly followed by the unengaged portions of the Dutch line. With the arrival of British reinforcements and the retreat of sections of the Dutch fleet, the battle was almost complete; the battered Wassenaar surrendered for the second time, to Russell, while Admiraal Tjerk Hiddes De Vries and Gelijkheid, both of which were too badly damaged to escape, also struck their colours. Eventually only the Dutch flagship remained in combat.
For an hour De Winter continued his resistance, with Director holding station off the stern of Vrijheid and repeatedly raking it. By 15:00, all three masts had been brought down, obstructing the fire of the starboard battery, while De Winter was the only officer who remained uninjured, standing on his wrecked quarterdeck and still refusing to lower his colours. In an attempt to settle the combat, Captain William Bligh of Director closed to within 20 yards (18 m) of the Dutch flagship and demanded to know if De Winter surrendered. The Dutch admiral replied "What do you think about it?", and then attempted to personally raise signals demanding reinforcements from the rest of his fleet, only to find that the halyards had been shot away. De Winter then summoned the ship's carpenter and ordered him to repair his barge, so that the admiral could transfer command to another ship and continue the battle. When British sailors from Director boarded the drifting flagship, De Winter was discovered assisting the carpenter with repairs to the barge. On being informed that he was a prisoner of war, he replied "This is my destiny not foreseen" and, after checking on a mortally wounded officer who lay on the quarterdeck, he followed the boarding party back to their boat for the trip to Venerable.
De Winter was immediately taken to see Duncan, the Dutch officer holding out his sword as a token of surrender. Duncan refused the weapon, instead shaking De Winter's hand and insisting "I would much rather take a brave man's hand than his sword". In addition to the losses in the rear, five ships of the Dutch van had been captured as well as the frigate Ambuscade that had attacked from the second line. The remainder of the Dutch ships had fled, making rapid progress towards the coastal shallows. Duncan did not follow them: the Dutch coast between Kamperduin and Egmond was only 5 nautical miles (9.3 km) away, his ship lay in just 9 fathoms (18 yards (16 m)) of water and the weather was too fierce and his ships too battered to risk combat in shoal waters. Instead he ordered his ships to ensure control of their prizes and to return to Britain. Many ships were now undermanned due to the terrible casualties they had suffered: surgeon Robert Young of Ardent, the worst hit of the British ships, worked for more than twelve hours without a break and later wrote:
Melancholy cries for assistance were addressed to me from every side by wounded and dying, and piteous moans and bewailing from pain and despair. In the midst of these agonising scenes I was able to preserve myself firm and collected… Many of the worst wounded were stoical beyond belief; they were determined not to flinch and, when news of the shattering victory was brought down to them, they raised a cheer and declared they regretted not the loss of their limbs.—Quoted in Peter Padfield, Nelson's War (1976)
Casualties in the battle were very heavy on both sides, and historians such as William James have noted that the losses among the British ships were proportionally much higher than when British fleets met French or
