Castaños wins at Bailén
On 19 July, in the olive groves of Andalusia, the Spanish general Francisco Javier Castaños forces the surrender of an entire French corps under General Dupont — the first capitulation of a Napoleonic army in open battle and the spark of European hope against the Empire.
News of Bailén raced through Europe: in Vienna and Berlin patriots read of an army of Napoleon laying down its arms in the heat of the Sierra Morena. Joseph Bonaparte abandoned Madrid within days; Napoleon would have to come in person at the head of two hundred and fifty thousand men to restore his brother's throne. The Peninsular War — la Guerra de la Independencia — settled into six years of sieges, guerrilla, and Wellington's slow advance from Lisbon to the Pyrenees.
