Battle of Ocaña, 19 November 1809

Background. The Spanish campaign in late 1809 aimed for armies to lunge at Madrid from both north and south. Following the Battle of Talavera, Soult was appointed chief of staff of French forces in Spain with extended powers. This strategic context set the stage for the engagement at Ocaña, where French forces would confront the Spanish Army of the Center.

Engagement. On 19 November, French forces executed a Cannae-like encirclement of the Spanish army. A massed battery pounded the Spanish center while Leval attacked Castejon and Werlé assaulted Lacy's division. The battle was tactically decisive, representing the worst defeat ever suffered by a Spanish army on home soil, driven largely by the French use of cavalry.

Aftermath. General Aréizaga's army of 51,000 troops suffered nearly 19,000 casualties, including killed, wounded, prisoners, and deserters. This loss constituted the Spanish army's greatest single defeat in the Peninsular War. In the aftermath, the French Imperial Army pillaged Ocaña, reflecting the severity of the French victory and the disruption of Spanish forces.
