Meanwhile, some of the crew, led by seaman Vizard, are preparing a written petition for better conditions, in conjunction with similar efforts throughout the British fleet.
Crawford dispatches his son as part of the prize crew tasked to sail the captured merchantman to a British port, thereby placing him out of Scott-Padget's reach.
