Battle of Graz

The Battle of Graz took place on 24–26 June 1809 between an Austrian corps commanded by Ignaz Gyulai and a French division led by Jean-Baptiste Broussier. The French were soon reinforced by a corps under Auguste Marmont. The battle is considered a French victory though Gyulai was successful in getting supplies to the Austrian garrison of Graz before the two French forces drove him away from the city. Graz, Austria is located 145 kilometers south-southwest of Vienna at the intersection of the modern A2 and A9 highways.

Before the Battle of Raab on 14 June, the Franco-Italian army left Broussier's division in its rear to besiege an Austrian garrison in the Graz citadel. When Gyulai's force appeared before the town in late June, Broussier retreated, allowing the Austrians to resupply the garrison. On the night of 25 June, Broussier sent two unsupported battalions of the 84th Line Infantry Regiment against the town. Surrounded by a greatly superior force of Austrians, the French stubbornly defended their position until the next afternoon, then broke out of the encirclement.

The 84th was soon joined by Auguste Marmont's newly arrived French corps. Marmont then attacked and forced Gyulai to retreat from Graz. The castle hill, however, remained in possession of its Austrian garrison. Shortly afterward, Emperor Napoleon I summoned both Marmont and Broussier to march to Vienna, where both participated in the climactic Battle of Wagram on 5 and 6 July. In recognition of its heroic action, the 84th was allowed to inscribe UN CONTRE DIX (One Against Ten) on its colors.
