The author recounts his early naval career from adolescence through active service in the 1850s, describing training, shipboard routine, punishments, leisure, and social life aboard various vessels. He relates participation in mid-century campaigns, including operations in the Black Sea and in China, and narrates incidents such as a shipwreck, pirate-hunting, and the formation and actions of naval brigades during colonial disturbances. Interwoven are portraits of senior officers, practical seafaring detail, reflections on discipline and camaraderie, and personal anecdotes that trace the transition from cadet to seasoned officer.
