Fatigue duty

[1][2] Parties sent on fatigue duty were known in English by the French term "en détachement" according to an 1805 military dictionary.

[1][5] US soldiers on fatigue duty were allowed an extra gill of whiskey by the act of March 2, 1819.

[5] For a time in the 1870s, US Marine Corps company grade officers were supposed to wear an English model "pillbox" or "round cap" for fatigue duty, but it was never popular.

[7]During the American Civil War, Black soldiers were constantly assigned to fatigue labor, to the point it had become regular slavery.

Commitments to avoid this discrimination were expressed – General Lorenzo Thomas had released the General Orders 21 outlawing discriminatory fatigue labor – but powerful US army leaders often turned a blind eye to this progressive intention whenever deemed necessary.
