The
kepi is a
cap with a flat circular top and a
visor (
American English) or peak (
British English). The word came into the
English language from
French, in which it is written with an acute accent
képi. It can be translated as "small cap".
The kepi was formerly the most common headgear in the French Army. Its predecessor originally appeared during the 1830s, in the course of the initial stages of the occupation of Algeria, as a series of various lightweight cane-framed cloth undress caps called casquette d'Afrique. These were intended as alternatives to the heavier, cloth-covered leather French Army shako. As a light and comfortable headdress it was adopted by the metropolitan (French mainland) infantry regiments for service and daily wear, with the less practical shako being relegated to parade use. In 1852, a new soft cloth cap was introduced for campaign and off-duty. Called bonnet de police à visière, this was the first proper model of the kepi. The visor was generally squarish in shape and oversized and was referred to as bec de canard (duck bill). This kepi had no chinstrap (jugulaire). Subsequent designs reduced the size of the cap and introduced chinstraps and buttons. The kepi became well known outside France during the Crimean War and was subsequently adopted in various forms by a number of other armies (including the U.S. and Russian) during the 1860s and 1870s.
In 1876, a new model appeared with a rounded visor, as the squared visor drooped when dry and curled up when drying out. The model used in World War I was the 1886 pattern, which was a fuller shape incorporating air vents.
By 1900 the kepi had become the standard headdress of most French army units and (along with the red trousers of the period 1829-1914) a symbol of the French soldier. It appeared in full dress (with inner stiffening and ornamental plume or ball ornament) and service versions. Officers' ranks were shown by gold or silver braiding on the kepi. The different branches were distinguished by the colours of the cap - see the table. Cavalry normally wore shakos or plumed helmets, reserving red kepis with light or dark blue bands for wear in barracks. General officers wore (and continue to wear) kepis with gold oak leaves embroidered around the band.
