The honours of war became traditional in the age of early modern warfare, when sieges were more common, and logistical challenges made it difficult to corner a defeated enemy after a battlefield victory. However, the practice continued into the age of industrial warfare. After the Siege of Metz (1870), the Prussians offered honours of war to the capitulating French army, but the French general Bazaine refused to accept them. In World War II, the Germans granted the honours of war to the defeated French garrison at the Siege of Lille (1940), and the British granted the honours of war to the defeated Italian army at the Battle of Amba Alagi (1941).
