Medieval warfare
Supplies and logistics
Medieval Warfare largely predated the use of supply trains- which meant that armies had to acquire food supplies from whatever territory they were passing through, this meant that large scale looting by soldiers was unavoidable, and was actively encouraged by the 14th century with its emphasis on "Chevaunche" tactics, or use of units of light cavalry who would loot and pillage hostile territory in order to distract and demoralize the enemy while denying them their supplies.
