The Battle of Ushant (also called the First Battle of Ushant) took place on 27 July 1778, during the American War of Independence, fought between French and British fleets 100 miles (160 km) west of Ushant, a French island at the mouth of the English Channel off the north-westernmost point of France.

Background

The British had 30 ships of the line commanded by Admiral the Honourable Augustus Keppel in HMS Victory. The French had 29 ships commanded by Admiral Louis Guillouet, comte d'Orvilliers.

Keppel put to sea from Spithead on 9 July 1778 with a force of 30 ships of the line. He sighted a French fleet of 29 sail west of Ushant on 23 July. Comte d'Orvilliers, who had orders to avoid battle, was cut off from Brest but retained the weather gage. Two of his ships to windward escaped into port leaving him with 27.

Battle

The two fleets manoeuvred during shifting winds and a heavy rain squall until a battle became inevitable with the British more or less in column and the French in some confusion. However, the French managed to pass along the British line to windward with their most advanced ships. At around noon, opened fire on Bretagne, 110 guns, followed by Ville de Paris, 90 guns. The British van escaped with little loss but Sir Hugh Palliser's rear division suffered considerably. Keppel made the signal to wear and follow the French, but Palliser did not conform and the action was not resumed.

Aftermath

A violent quarrel, exacerbated by political differences, broke out between the British commands. This led to two courts-martial, the resignation of Keppel, and to great injury to the discipline of the navy. Keppel was court-martialled but cleared of dereliction of duty charges. Palliser was criticized by an inquiry, before the affair turned into a squabble of party politics.
