. Within an hour of their opening volleys the British and French lines were hopelessly confused, with three separate engagements being fought within sight of one another. In the van,
Caesar had finally attempted to join the fight, only to have a vital spar shot away by
Trajan which caused her to slip down the two embattled fleets without contributing significantly to the battle.
Bellerophon and
Leviathan were in the thick of the action, the outnumbered
Bellerophon taking serious damage to her rigging. This left her unable to manoeuvre and in danger from her opponents, of which
Éole also suffered severely. Captain
William Johnstone Hope sought to extract his ship from her perilous position and called up support; the frigate under Captain
Edward Thornbrough arrived to provide assistance. Thornbrough brought his small ship between the ships of the French battleline and opened fire on
Éole, helping to drive off three ships of the line and then towing
Bellerophon to safety.
Leviathan, under
Lord Hugh Seymour, had been more successful than
Bellerophon, her gunnery dismasting
America despite receiving fire from
Éole and
Trajan in passing.
Leviathan only left
America after a two-hour duel, sailing at 11:50 to join
Queen Charlotte in the centre.
Russell had not broken the French line and her opponent
Témeraire got the better of her, knocking away a topmast and escaping to windward with
Trajan and
Éole.
Russell then fired on several passing French ships before joining
Leviathan in attacking the centre of the French line.
Russells boats also took the surrender of
America, her crew boarding the vessel to make her a prize (although later replaced by men from
Royal Sovereign)
Royal Sovereign lost Admiral Graves to a serious wound and lost her opponent as well, as
Terrible fell out of the line to windward and joined a growing collection of French ships forming a new line on the far side of the action. Villaret was leading this line in his flagship
Montagne, which had escaped from
Queen Charlotte, and it was
Montagne which
Royal Sovereign engaged next, pursuing her close to the new French line accompanied by
Valiant, and beginning a long-range action. Behind
Royal Sovereign was
Marlborough, inextricably tangled with
Impétueux. Badly damaged and on the verge of surrender,
Impétueux was briefly reprieved when
Mucius appeared through the smoke and collided with both ships. The three entangled ships continued exchanging fire for some time, all suffering heavy casualties with
Marlborough and
Impétueux losing all three of their masts. This combat continued for several hours. Captain Berkeley of
Marlborough had to retire below with serious wounds, and command fell to Lieutenant
John Monkton, who signalled for help from the frigates in reserve.
Robert Stopford responded in , which had the assignment of repeating signals, and towed
Marlborough out of the line as
Mucius freed herself and made for the regrouped French fleet to the north.
Impétueux was in too damaged a state to move at all, and was soon seized by sailors from HMS
Russell. Dismasted,
Defence was unable to hold any of her various opponents to a protracted duel, and by 13:00 was threatened by the damaged
Républicain moving from the east. Although
Républicain later hauled off to join Villaret to the north, Gambier requested support for his ship from the fleet's frigates and was aided by under Captain
William Bentinck. As
Impétueux passed she fired on
Phaeton, to which Bentinck responded with several broadsides of his own.
Invincible, the only ship of the forward division of the British centre to engage the enemy closely, became embroiled in the confusion surrounding
Queen Charlotte.
Invincibles guns drove
Juste onto the broadside of
Queen Charlotte, where she was forced to surrender to Lieutenant
Henry Blackwood in a boat from
Invincible. Among the other ships of the division there were only minor casualties, although lost several
yards and was only brought back into line by the quick reactions of two junior officers, Lieutenant
Robert Otway and Midshipman
Charles Dashwood. '', painted by
Mather Brown. The conflict between
Queen Charlotte and
Montagne was oddly one-sided, the French flagship failing to make use of her lower-deck guns and consequently suffering extensive damage and casualties.
Queen Charlotte in her turn was damaged by fire from nearby ships and was therefore unable to follow when
Montagne set her remaining sails and slipped to the north to create a new focal point for the survivors of the French fleet.
Queen Charlotte also took fire during the engagement from , under
Thomas Mackenzie, which had failed to close with the enemy and instead fired at random into the smoke bank surrounding the flagship. Captain
Sir Andrew Snape Douglas was seriously wounded by this fire. Following
Montagne's escape,
Queen Charlotte engaged
Jacobin and
Républicain as they passed, and was successful in forcing the surrender of
Juste. To the east of
Queen Charlotte,
Brunswick and
Vengeur du Peuple continued their bitter combat, locked together and firing main broadsides from point blank range. Captain Harvey of
Brunswick was mortally wounded early in this action by
langrage fire from
Vengeur, but refused to quit the deck, ordering more fire into his opponent.
Brunswick also managed to drive
Achille off from her far side when the French ship attempted to intervene.
Achille, already damaged, was totally dismasted in the exchange and briefly surrendered, although her crew rescinded this when it became clear
Brunswick was in no position to take possession. With her colours rehoisted,
Achille then made what sail she could in an attempt to join Villaret to the north. It was not until 12:45 that the shattered
Vengeur and
Brunswick pulled apart, both largely dismasted and very battered.
Brunswick was only able to return to the British side of the line after being supported by
Ramillies, while
Vengeur was unable to move at all.
Ramillies took
Vengeurs surrender after a brief cannonade but was unable to board her and instead pursued the fleeing
Achille, which soon surrendered as well. To the east,
Orion and
Queen forced the surrender of both
Northumberland and
Jemmappes, although
Queen was unable to secure
Jemmappes and she had to be abandoned later.
Queen especially was badly damaged and unable to make the British lines again, wallowing between the newly reformed French fleet and the British battleline along with several other shattered ships.
Royal George and
Glory had between them disabled
Scipion and
Sans Pareil in a bitter exchange, but were also too badly damaged themselves to take possession. All four ships were among those left drifting in the gap between the fleets. ==French recovery==
