HMS Victory was the largest warship afloat in her day, built from roughly 6,000 felled oak trees and rigged with 27 miles of rope, carrying firepower a land general could only envy. The film traces her from the shipyard through decades of service to the role that made her famous: flagship to Admiral Horatio Nelson at Trafalgar in 1805. It covers Nelson's reputation as both a brilliant tactician and a man dogged by personal scandal, and follows Victory's design and construction in detail, from timber selection to the guns that made her a floating arsenal. Historians walk through the ship's later preservation and her current status as the world's oldest naval ship still in commission, docked at Portsmouth. The narrative moves between battle history and the practical craft of wooden shipbuilding, giving equal weight to Nelson's leadership at sea and the raw material cost of keeping a warship like Victory afloat and fighting.
