A portable stretcher or carrying chair used to transport wounded soldiers or sick people over rough mountain terrain.
From French cacolet, origin disputed but possibly from a variant of 'caquois' or related to carrying. It became a standard military medical term for field transport in mountainous regions.
The cacolet was revolutionary for mountain warfare—a special frame-chair that could carry a wounded soldier across impossible terrain where wagons couldn't go, basically a medieval MEDEVAC system.
