A speculative discussion of HMS Warrior entering Hampton Roads shifts attention from guns and armor to pilotage and charts. A large ship operating in restricted waters needs precise local knowledge before its combat power matters. The Royal Navy's strong survey tradition and habit of retaining earlier data would have made previous expeditionary experience operationally valuable. Hydrography and institutional memory can shape what a fleet is physically able to attempt.

A Hampton Roads counterfactual turns on pilotage, hydrographic skill, and the Royal Navy's habit of preserving survey knowledge from earlier operations.
