Camp follower

Camp follower is a term used to identify civilians and their children who follow armies. There are two common types of camp followers; first, the wives and children of soldiers, who follow their spouse or parent's army from place to place; the second type of camp followers have historically been informal army service providers, servicing the needs of encamped soldiers, in particular selling goods or services that the military does not supply—these have included cooking, laundering, liquor, nursing, sexual services and sutlery.

From the beginning of organized warfare until the end of the 19th century, European and American armies heavily depended on the services of camp followers. These services included delivery and preparation of provisions and transportation of supplies, which augmented the official military support structure. Camp followers usually accompanied the baggage train and they often outnumbered the army itself, adding to its logistical problems. Camp followers were both a support and drain on an army. They provided valuable services. Soldiers' wives washed, sewed, nursed and even acted as servants. However, camp followers needed to be fed, clothed, transported and guarded. They also had to be policed; camp followers could be among the most determined scavengers and looters after battles and whilst on the march.

From the middle of the 19th century on, the creation of organized and resourced transport, medical, ordnance and supply corps as an integral part of regular armies marked the end of reliance on camp followers in most European armies. However, in much of the world the concept of numerous civilian workers, family members and hangers-on accompanying armies survived into the 20th century, either for reasons of local culture or in the absence of formal support services. A notable example was the Mexican Revolution of 1910-20, where female soldaderas filling traditional camp roles, carrying equipment and often acting as combatants were a marked feature of Zapatista, Villistas and Federale forces at all times.
