The Battle of Beaune-la-Rolande on 28 November 1870 was a battle of the Franco-Prussian War, won by Prussia. In an attempt to relieve the Siege of Paris, French General Crouzat's XX Corps launched an attack against three Prussian brigades resting in Beaune-la-Rolande. These brigades were from the Prussian X Corps which was detailed to guard the flanks and rear of the force besieging Paris and provide early warning of any French counter-attacks. The French committed a force of 60,000 men, largely conscripts of the Garde Mobile, and 140 guns against the Prussians 9,000 men and 70 guns, mostly drawn from regular troops.
