The Fatigue call is a signal that indicates Scouts need to prepare for work details such as maintenance or cleaning. The use of such signals ensured that all Scouts are aware of the requirement to prepare for and perform these duties, maintaining discipline and order within the Troop.
In historical military practice, a specific sound or bugle call would be used to alert troops to these duties. The term "fatigue" in a military context refers to a call to duty or work, often related to manual labor or tasks outside regular combat duties. This signal served as a warning that it was time to assemble and get ready for assigned work details, ensuring the orderly and efficient execution of necessary but often mundane tasks essential for the functioning of a military unit.
