Spain's armies also peaked at around 200,000 men, not including more than 50,000 guerrillas scattered over Spain. In addition the Maratha Confederation, the Ottoman Empire, Italy, Naples and the Duchy of Warsaw each had more than 100,000 men under arms. Even small nations now had armies rivalling the size of the Great Powers' forces of past wars but most of these were poor quality forces only suitable for garrison duties. The size of their combat forces remained modest yet they could still provide a welcome addition to the major powers. The percentage of French troops in the Grande Armee which Napoleon led into Russia was about 50% while the French allies also provided a significant contribution to the French forces in Spain. As these small nations joined the coalition forces in 1813–1814, they provided a useful addition to the coalition while depriving Napoleon of much needed manpower.
