Custer was interred at West Point in 1877 but an appointed committee could not raise enough funds for an equestrian statue to mark his grave. So in 1880 James Wilson MacDonald was hired to create an 8 foot bronze of Custer armed with a pistol and sword. As you say Libby objected to the finished image and convinced Robert Lincoln, secretary of war, to remove the statue in 1884. She also squashed plans for a copy of the statue to be erected in D.C. The statue went into storage at West Point until about 1900 when it was sent to Stanford White at an ornamental foundry in NYC who was to sever the statue to create a bust.
White was shot to death in a sex scandal that rocked the city in 1906. The whereabouts of the statue in now unknown.
Libby had an obelisk erected on the statue's pedestal at West Point.
Michigan appropriated $25K for an equestrian statue for Custer that was built in Monroe, MI in 1910.
