Camisado

In military tactics, a camisado or camisade is a surprise attack occurring at night or at daybreak, when the enemy are supposed to be asleep.^[1]

The term comes from Spanish camisa (shirt): when the Tercio had actions (skirmishes) of around fifty men attacking at night with minimum equipment, only sword and dagger (although some soldiers could carry arquebus or musket), and they were dressed only with a white shirt (thus the Spanish word es:encamisada), in order to kill in silence as many enemies as possible while they were sleeping. This is reflected in the film Alatriste, based on the main character of The Adventures of Captain Alatriste (Las aventuras del Capitán Alatriste), a series of novels written by Arturo Pérez-Reverte.
