Russian Winter, sometimes personified as "General Frost"[1] or "General Winter",[2] is an aspect of the climate of Russia that has contributed to military failures of several invasions of Russia. Mud is a related contributing factor that impairs military maneuvering in Russia and elsewhere, and is sometimes personified as "General Mud".[3][4] Russians call those muddy conditions rasputitsa, which occur with autumnal rains and spring thaws in Russia and make transport over unimproved roads difficult.
