How Grenada exposed contested colonial waters

How does the Battle of Grenada fit the claim that Britain lost sea control?

Grenada was part of a wider period in which French fleets could challenge Britain and take territory in colonial waters, making sea control contested or locally lost.

The 1779 Battle of Grenada forms part of the wider loss of British freedom of action in colonial waters. French fleets could operate around British possessions and take territory without effective British challenge. A fleet able to enter and fight in those waters made Britain's command disputable. The extent of that French freedom of action determines whether control had become contested or had been lost locally. The French did not ultimately achieve every objective, but their ability to operate there still challenged British control.
