I want to know the answer to the following question:
Where did Victoria visit that led her to reprimand Derby for the state of the Royal Navy?
All the background I'm provided with is that "Victoria and Albert attended the opening of a new basin at the French military port of Cherbourg on 5 August 1858, in an attempt by Napoleon III to reassure Britain that his military preparations were directed elsewhere.". Is that enough to answer the question?
