War of the Pyrenees
Following the execution of Louis XVI of France by the French revolutionaries, Portugal enters the anti-revolutionary Coalition. In 1793, the Portuguese Navy was tasked with transporting by sea and escorting the Portuguese Expeditionary Army sent to help Spain in the War of the Pyrenees against France. This was done by the Transport Squadron organized with four ships of the line, one frigate, four transport ships and 10 merchant ships.
