Grant freed his slaves —
In Mary Robinson’s July 24, 1885, recollections, during an interview for the St. Louis Republican memorial to Grant following his death, she noted that “he always said he wanted to give his wife’s slaves their freedom as soon as he was able.” In 1859, Grant freed William Jones, the only slave he is known to have owned. During the Civil War, some slaves at White Haven simply walked off, as they did on many plantations in both Union and Confederate states. Missouri’s constitutional convention abolished slavery in the state in January 1865, freeing any slaves still living at White Haven.
“I Ulysses S. Grant…do hereby manumit, emancipate and set free from Slavery my Negro man William, sometimes called William Jones…forever.”
