Battle of Gravelotte
The Battle of Gravelotte (or Battle of Gravelotte–St. Privat) on 18 August 1870 was the largest battle of the Franco-Prussian War. Named after Gravelotte, a village in Lorraine, it was fought about west of Metz, where on the previous day, having intercepted the French army's retreat to the west at the Battle of Mars-La-Tour, the Prussians were now closing in to complete the destruction of the French forces.
