On 21 February 1744, the combined Franco-Spanish fleet of twenty-seven
ships of the line and three
frigates put to sea with Mathews in pursuit. The British ships were generally larger and more heavily armed than their opponents, carrying over 25% more cannons overall. Both fleets adopted the traditional formation of
vanguard, centre and rear, with Navarro and the Spanish ships in front, followed by two French squadrons. On the British side, Mathews led the van,
William Rowley the centre, and Lestock the rear. Light winds made manoeuvring difficult and caused the two fleets to become spread out but around 11:30 early in the evening of 21 February, the fleets began to approach each other and prepare for battle, with Mathews signalling his ships to form
line of battle. Since the line had not been properly formed as night fell, Mathews hoisted the signal to
come to or halt by turning into the wind, intending his ships to first finish forming the line. The main action was being fought around
Real Felipe, Navarro's flagship.
Marlborough purposefully crossed the Spanish line, but suffered such severe damage that she was deemed to be on the verge of sinking. The
Hercules, astern of the
Real Felipe, vigorously fought off three British ships. The
Constante, immediately ahead of the flagship, repelled the attack of a British ship-of-the-line, which was promptly replaced by two more, with which she continued to fight for nearly three hours. The French ships came about at 5:00 pm to aid the Spanish, a manoeuvre interpreted by some of the British commanders as an attempt to double the British line and surround them. The Spanish, still on the defensive, neglected to capture the defenceless
Marlborough, though they did retake the
Poder, which had previously surrendered to the British. The Franco-Spanish fleet then resumed their flight to the southwest, and it was not until 23 February that the British were able to regroup and resume the pursuit. They caught up with the enemy fleet again, which was hampered by towing damaged ships, and the unmanoeuvrable
Poder was abandoned and scuttled by the French. By now the British had closed to within a few miles of the enemy fleet, but Mathews again signalled for the fleet to come to. The following day, 24 February, the Franco-Spanish fleet was almost out of sight, and Mathews returned to Hyères and sailed from there to
Port Mahon, where he arrived in early March. ==Aftermath==
