Bailén

19 Jul 1808 — Spanish regulars and levies force 18,000 French troops to capitulate — the Empire’s first surrender in the open field. Europe takes note: they can be beaten.

THE MOMENT IN CONTEXT

Napoleon could not invade Britain after Trafalgar, so he tried instead to close continental markets to British goods. Portugal refused to comply, so French troops crossed Spain in 1807, and Napoleon then forced the Spanish royal family to abdicate and installed his brother Joseph Bonaparte. Madrid rose on 2 May 1808 and was answered with severe reprisals. Local juntas, or emergency councils, then claimed authority in the absent king’s name.
