Cause

A large French convoy of 250 merchant ships, escorted by eight ships of the line under Vice Admiral Herbiers, set out from the Basque Roads bound for the West Indies. A British fleet of fourteen ships of the line under Rear-Admiral Edward Hawke intercepted the convoy, triggering a confrontation.

Event

Herbiers ordered the merchant vessels to scatter and formed his warships into a line of battle to draw the British away. Hawke advanced and enveloped the rear of the French line, bringing superior numbers against each French vessel in turn. Six French warships were captured along with 4,000 seamen, while only seven of the 250 merchant ships were taken.

Consequence

The British victory severed French communications with their overseas colonies, cutting off supply and reinforcement. The War of the Austrian Succession ended the following year; under the Treaty of Aix-la-Chapelle, France recovered its captured colonial possessions in exchange for withdrawing from territorial gains in the Austrian Netherlands.
