The French commander was under orders to avoid battle if possible, in order to maintain a fleet in being.^[3] The commanders of the two squadrons of the British fleet were already personally and politically at odds with each other, and failed to make a concerted attack on the French.^[4]

The battle, which was the first major naval engagement in the Anglo-French War of 1778, ended indecisively with no ships lost on either side and led to recriminations and political conflicts in both countries.

The British had a fleet of thirty ships-of-the-line, four frigates, and two fire-ships commanded by Admiral Augustus Keppel, in HMS Victory, which sailed from Spithead on 9 July.^[5] The French fleet had thirty-two ships-of-the-line, seven frigates, five corvettes and one lugger, commanded by Vice-Admiral Comte d'Orvilliers, who had sailed from Brest on 8 July.^[6] Keppel sighted the French fleet west of Ushant at just after noon on 23 July.^[6] Keppel immediately ordered his battleships into line and set off in pursuit. At around 7 o'clock in the evening, the French fleet went about and began heading towards the British. Keppel, who did not wish to engage at night, had his ships hove to in response.^[7] In the morning, d'Orvilliers found himself to the north-west of the British fleet and cut off from Brest, although he retained the weather gage. Two of his ships, standing to leeward, escaped into port, leaving him with thirty ships-of-the-line.^[7] Keppel tried for three days to bring the French to action but d'Orvilliers declined, maintaining his position upwind and heading into the Atlantic.^[7]

At 6 a.m. on 27 July, with the British fleet roughly line-abreast, Keppel gave the order for the rear division, several miles away under Sir Hugh Palliser, to chase to windward. At 9 a.m., the French, who had hitherto been sailing in the same direction, several miles to windward, went about once more. As the rearmost ships of the French fleet were tacking, however, the wind changed allowing the British to close the gap between them and their quarry.^[7] At 10:15 the British were slightly to leeward, line-ahead on the same course as the French. A little later, a change in wind direction brought about a rain squall which cleared at around 11 o'clock. A further change in wind direction to the south-west gave advantage to the British which d'Orvilliers sought to negate by ordering his ships about. The French, now heading towards the British in a loose formation, would pass slightly to windward.^[8]

The French ships were a few points off the wind and d'Orvilliers ordered them close hauled which caused the French line to veer slightly away from the British. The battle began at 11:20 when the fourth French ship in the line was able to bring her guns to bear. Keppel, who wished to save his salvo for the enemy flagship, received the broadsides of six French ships without reply. Once he had engaged the 110-gun Bretagne, he continued to attack the next six ships in the French line.^[8]

As the British van under Robert Harland passed the end of the French line, Harland ordered his ships about so as to chase the French rearguard, including the Sphinx.^[8] Palliser's ten ships at the rear had not formed line of battle but were instead in a loose irregular formation. This was in part due to Keppel's earlier order to break off and chase the French ships to windward. Palliser's division therefore was badly mauled, having allowed itself to be attacked piecemeal.^[9] At 1 p.m. Victory passed the last French ship and attempted to follow Harland but was so badly damaged in the masts and rigging that Keppel had to wear round and it was 2 p.m. before his ships were on the opposite tack. It was about this time that Palliser in Formidable emerged from the battle, downwind of Keppel's division.^{[citation needed]}

Meanwhile, the French line had tacked and was now heading south on the starboard tack and threatening to pass the British fleet to leeward. The French practice of firing high into the rigging had left several of the British ships disabled and it was this group that Keppel now stood down towards whilst making the signal, 'form line of battle'.^[9] By 4 p.m., Harland's division had gone about and joined Keppel's ships in line but Palliser would not or could not conform and his ships, misunderstanding Keppel's intentions, formed line with their commander, several miles upwind from the rest of the British fleet. D'Orvilliers did not, however, attack the British fleet while it was divided into three sections but instead continued his course, passing the British fleet to leeward.^[10]

At 5 p.m., Keppel sent the sixth-rate, HMS Fox, to demand that Palliser join the main body of the fleet and when this failed, at 7, Keppel removed Palliser from the chain of command by individually signalling each ship in Palliser's division.^[11] By the time those ships had joined Keppel, night had fallen and, under cover of darkness, the French fleet sailed off. By daylight the French were 20 miles away and with no chance of catching them, Keppel decided to return to Plymouth to repair his ships.^[11]
