On the morning of the battle, a squadron of six French galleys, whose commodore, the Chevalier de Langeron, flew his flag in the La Palme, set out from Dunkirk in good weather. With the commodore was Captain Smith, a renegade Englishman, who had obtained authority to attack and pillage the town of Harwich, using de Langeron's squadron which carried the incendiary materials and a division of soldiers. Smith had served in the Royal Navy and on several merchant ships, acquiring a good knowledge of both channel coasts. But he was never a captain in the Royal Navy. A Jacobite, he had an implacable hatred for the Protestant Queen and administration of England.

The squadron arrived in the mouth of the Thames early in the evening, but Smith commanded them to withdraw somewhat so that they could land at Harwich in the dark. Hardly had they hove-to than a lookout reported an English convoy thirty-five merchantmen and an escorting frigate to the northward, heading west. This was a merchant convoy from the Texel (at the mouth of the Zuiderzee) bound for the Thames, escorted by HMS Nightingale.

The French Commodore called a council of war, which decided to try to capture the convoy instead of attacking Harwich – much to Smith's annoyance. The plan was that four galleys should cut the merchantmen off from the Thames, and that La Palme and the Chevalier de Mauvilier's galley should overcome the frigate. All galleys set sail and rowed hard towards the approaching English ships, and Nightingale soon realised that the convoy was in danger. Captain Jermy ordered the merchantmen to crowd on all sail and make for the Thames, while he would engage the galleys.

Nightingale set full sail for the two galleys, themselves propelled by forced rowing since night was approaching. La Palme, a league ahead of her consort, fired at the frigate when within range, but without response, and at musket range the French musketeers opened fire. Nightingale suddenly went about, as if to flee. The French called the English cowards, and de Langeron ordered his galley to drive its beak, the strongest part, into Nightingale's stern, her weakest point, preparatory to boarding her.

Just as the beak was about to strike, Nightingale, by a clever stroke of the helm, evaded the galley and turned her broadside to it, so close that the galley's oars were broken. Nightingale secured La Palme with grappling irons, and fired a broadside of grapeshot; at the same time a hail of grenades came from aloft. Nightingale then sent fifty men aboard, to deal with any men still alive.

With La Palme rendered useless, de Langeron himself hoisted the distress signal to summon his squadron to his aid, even though the four galleys had already forced most of the convoy to strike sail. When the galleys turned back, the merchantmen set sail again and made for the Thames.

Nightingale was soon surrounded, and in no state to return either cannon or musket shot. Twenty-five grenadiers from each galley boarded the frigate, but were driven back by a murderous fire from the officers gathered under the poop, and by blows from the pikes and swords of the crew, who were under a grating set in the top deck. A second attack was repulsed. The French then had to force open the grating with crowbars to capture the crew, which they did, but not without considerable losses. The officers also gave a good account of themselves before being overcome.

All had now surrendered except Captain Jermy, who shut himself in his cabin under the poop, firing guns and pistols and declaring that he would not be taken alive. His officers told de Langeron that he would blow up the powder magazine, to which he had easy access, rather than surrender; this would threaten three thousand Frenchman's lives. The captain was civilly asked to surrender, but he again opened fire. A sergeant and twelve grenadiers were then sent to take him; the sergeant broke the cabin door and was immediately shot dead, whereupon the grenadiers fled.

These delays enabled Jermy to see, from their lights, that the merchantmen had all reached the protection of the River Thames. However, to gain more time, Jermy said that he would only surrender his sword to the commodore in person. A truce was arranged, and de Langeron replied that a commodore should not quit his post. Jermy, now sure that the convoy was safe, gave up his sword. When Jermy was brought to the French officers, they were surprised to see "a very little man, quite deformed and hunchbacked." The commodore complimented him on his bravery; he replied, "I have no regret for the loss of my ship, since I have succeeded in my design, which was to save the convoy entrusted to my care. As for myself, if you treat me as a man of honour, I, or some other of my nation, may some day have the opportunity of acting in the same way towards you." de Langeron was quite taken by these remarks, and returned Jermy's sword, saying "Take back this sword, sir; you well deserve to wear it, and you are my prisoner only in name." But soon Jermy had to be restrained from using his sword, for he saw the renegade Smith in the cabin and tried to attack him.

Jermy's wife was able to secure an audience with Queen Anne for his exchange, and in 1708 he was returned to England. He faced a routine court-martial for the loss of his ship, and was honourably acquitted. He was immediately given command of the Swallow Prize, and in 1710 was appointed to the Antelope, on which he served until he was superannuated in 1712.
