The author follows Robert Fulton’s transformation from artist to engineer and centers on his systematic pursuit of underwater navigation, describing construction and trials of an early submersible, detailed manuscript drawings, and technical innovations for propulsion and buoyancy. The narrative recounts negotiations, contracts, and arbitration with French and British authorities that affected development and deployment, situates Fulton amid earlier submarine experiments, and documents tests, political responses, and commercial pressures. A concluding technical analysis compares designs, assesses capabilities and limitations, and considers the implications of his work for naval warfare and later maritime engineering.
