Would HMS Agincourt appearing at the Battle of the Chesapeake secure a British victory in the American Revolutionary War?
Short answerIt would decisively win the naval battle, although that alone would not guarantee the final outcome of the wider war.
NotesThe Gin Palace nickname identifies the First World War HMS Agincourt after some initial uncertainty about the name. Putting that dreadnought into an Age of Sail battle creates an overwhelming mismatch. The expected result is the destruction of the opposing French fleet and a British victory at the Chesapeake. The response nevertheless leaves open whether the American rebellion would still succeed in the wider war.
