Generally most of the use of animal skins or linen wrapped in silk floss made of quilts and cold clothing, so in ancient times to the farmers in kind tax, to a large extent, is to ensure that the army's supply. But even so, soldiers frostbite frostbite death and other non-combat attrition also accounted for about three or four layers. This shows the impact of a harsh environment on warfare.

Therefore, the cold would cause the ancient people to do war unfavorably.
