Without undisputed control of the sea, Britain’s historic role as the unassailable bank and armory of the anti-French coalitions evaporates. The Napoleonic Wars would no longer be a story of eventual, total Allied victory, but would instead grind to a halt in a multipolar geopolitical stalemate.

Even if Trafalgar had ended in a stalemate or French-Spanish victory, Napoleon’s greatest weaknesses would have remained his continental overextension, the Spanish resistance, Britain’s financial resources, and Russia’s enormous strategic depth. I would predict that the Napoleonic Wars could have lasted another two to four years, potentially ending around 1817–1819 rather than 1815. The biggest change might not have been Napoleon’s ultimate defeat, but the greater difficulty Britain would have faced financing, supplying, and coordinating the coalition against him.
