Her biological gender was exposed after she was forced to medical attention after a duel with a fellow soldier.  In March 1696, she was arrested accused of desertion, during which her story was documented.  The documentation of her case is considered to have great historic value for several reasons: it documents a case of a female early modern age soldier without the sensationalism usually surrounding narratives of such occurrences; it also documents the life of a common foot soldier of the French army regardless of gender, as narratives of French foot soldiers of this epoch was quite rare.

The Thompson Brothers Rock Art is an inscribed rock located within Giant City State Park in Union County, Illinois.  Four names are carved into the rock, all but possibly one of which were inscribed by Union soldiers or supporters during the Civil War.  The two most prominent signatures belong to brothers Albert S. and T. W. Thompson; the former was a Union soldier, while the latter served as Deputy Provost Marshal and was responsible for locating Union deserters.  Union soldier Thomas L. Bailey also carved his name into the rock; the fourth name, A. Parker, may have been either a fellow soldier or a resident of the area who added his name after the war.  The rock was carved at a time when Union supporters and Southern sympathizers fought for control of southern Illinois, and as the Thompson family were among the most prominent Union supporters, it represents an attempt to physically claim the area for the North.  The Confederate sympathizers' inability to deface the names signifies their gradual loss of power in the area.  The rock is now one of the few surviving Civil War sites in Illinois.
