bivouac (French)

Where does "bivouac" come from?

The word bivouac originates from the Alemannic German term 'Biiwacht,' describing a patrol of citizens added to the regular town watch during times of alarm. Borrowed into French, the term evolved to describe the temporary encampment of soldiers resting in the field. It traveled from these local Swiss-German roots to become a standard military term for an overnight outdoor shelter.
