The French Army consisted in peacetime of approximately 400,000 soldiers, some of them regulars, others conscripts who until 1869 served the comparatively long period of seven years with the colours. Some of them were veterans of previous French campaigns in the Crimean War, Algeria, the Franco-Austrian War in Italy, and in the Franco-Mexican War. However, following the "Seven Weeks War" between Prussia and Austria four years earlier, it had been calculated that the French Army could field only 288,000 men to face the Prussian Army when perhaps 1,000,000 would be required. Under Marshal Adolphe Niel, urgent reforms were made. Universal conscription (rather than by ballot, as previously) and a shorter period of service gave increased numbers of reservists, who would swell the army to a planned strength of 800,000 on mobilisation. Those who for any reason were not conscripted were to be enrolled in the Garde Mobile, a militia with a nominal strength of 400,000. However, the Franco-Prussian War broke out before these reforms could be completely implemented. The mobilisation of reservists was chaotic and resulted in large numbers of stragglers, while the Garde Mobile were generally untrained and often mutinous.
