The order of battle of the Army of the Danube, a field army of the French First Republic, consisted of three divisions plus an advance guard, a reserve, and an artillery park. There were approximately 25,000 members of the Army of the Danube, the role of which was to invade southwestern Germany, precipitating the War of the Second Coalition. The artillery park was under the command of Jean Ambroise Baston de Lariboisière and consisted of 33 cannons and 19 howitzers. Initially, the Army included five future Marshals of France: its commander-in-chief, Jean-Baptiste Jourdan (pictured); François Joseph Lefebvre; Jean-Baptiste Drouet; Laurent de Gouvion Saint-Cyr; and Édouard Adolphe Casimir Joseph Mortier. After the Army's defeat in the Battle of Ostrach on 20–21 March 1799, the Army was reorganized and command shifted to another future marshal, André Masséna. The Army was disbanded that November and its units dispersed among other French field armies by mid-December. (Full list...)
