Grant and Lincoln's invitation

[Eva Elisabeth]

Kees, I think Mary left because the "Ord-incident" still "plagued" her (made her feel ashame), plus at the time she left the fall of Richmond was slow in coming. Abraham Lincoln, too, worried he had to go home without seeing this. Mary maybe felt she'd have to "hide" "open end" in her cabin and thus left. A return makes a fresh start easier. BTW, Carl Schurz also traveled a part of the way back with her. She left Tad with his father and to play with Gen. Grant's son.
Just to add - also aboard on April 6: James Speed and William T. Otto (Assistant Secretary of the Interior).
