The Armée de la Loire was a French army of the Franco-Prussian War. It was formed in October 1870 by Léon Gambetta, interior minister and minister for war in the Government of National Defence, then taking refuge in Tours after the French defeat at Sedan on 2 September 1870 had destroyed the Imperial field army. The newly raised force was formed out of francs-tireurs (volunteer irregulars), provincial Gardes Mobiles (territorials), naval forces, zouaves and tirailleurs from Algeria, plus regular soldiers in depots and reservists. Together these diverse units formed the 15th army corps under Joseph Édouard de la Motte Rouge. Apart from the North African units, the Army had few officers with fighting experience, insufficient artillery, and its troops were under-trained. It fought at the Battle of Orléans (1870) and Battle of Le Mans (1871) and was dissolved on 14 March 1871.
