Although Leale submitted a report in 1867 to Representative Benjamin F. Butler's House commission investigating the assassination, Leale's account of Lincoln's death was not publicly revealed until the 100th anniversary of Lincoln's birth in 1909. In that year Leale spoke on "Lincoln's Last Hour" to the New York commandery of the Military Order of the Loyal Legion of the United States. His 1865 written report to the Surgeon General of the United States was thought lost until 2008, when a 22-page photocopy was found in the Georgetown University Library and published.
