text_A: The scale of warfare dramatically enlarged during the Revolutionary and subsequent Napoleonic Wars. During Europe's major pre-revolutionary war, the Seven Years' War of 1756–1763, few armies ever numbered more than 200,000 with field forces often numbering less than 30,000. The French innovations of separate corps (allowing a single commander to efficiently command more than the traditional command span of 30,000 men) and living off the land (which allowed field armies to deploy more men requiring an equal increase in supply arrangements such as depots and supply trains) allowed the French republic to field much larger armies than their opponents. Napoleon ensured during the time of the French republic that separate French field armies operated as a single army under his control, often allowing him to substantially outnumber his opponents. This forced his continental opponents to also increase the size of their armies, moving away from the traditional small, well-drilled Ancien Régime armies of the 18th century to mass conscript armies.
text_B: Were the supply arrangements enough for the deployed men?
NO.
