Cherbourg combined an immense artificial harbor, fortifications, rail access, and a battle squadron only about sixty miles from Portsmouth. Napoleon III staged an imperial naval celebration to display French engineering, rising sea power, and renewed prestige. He hoped this standing menace would encourage British support or at least neutrality in future French conflicts. Britain instead treated the base as a coercive threat requiring more ships and stronger harbor defenses. The comparison with later German risk-fleet strategy shows why a threatening fleet could provoke British expansion rather than win concessions.
