This was contrary to the normal restrictions under which press gangs operated; which were intended to limit forced recruiting to professional sailors.
1 April 1803 saw the first of several landings carried out by the frigate Aigle, commanded by George Wolfe to capture men and press them into the navy.
Holding them prisoner, the landing force continued to Easton Square, where they were met by a large group of citizens who had received warning of the press gangs and had gathered to stop them.
The marines under his command also opened fire, and after the shooting stopped three people had been killed.
Wolfe and three officers stood trial for murder but were acquitted and left Portland, aboard Aigle, on 10 April to continue their patrol in home waters.
