At Gettysburg, when the corps was forced to retreat back through the town to Cemetery Hill, Col Charles Coster took a brigade of Steinwehr's division out to the edge of the town, where it sacrificed itself buying time for the retreating soldiers of the other two divisions.
Ved Gettysburg, da korpset blev tvunget til at trække sig tilbage gennem byen til Cemetery Hill, førte oberst Charles Coster en brigade fra Steinwehr's division ud til udkanten af byen, hvor den ofrede sig selv og dermed gav tid til at de retirerende tropper fra de to andre divisioner kunne nå i sikkerhed.
