Harry Truman actually said...

"Any such investigation, trial, or action so begun may be completed in accordance with the provisions of the Manual for Courts-Martial, 1928."

"Nothing contained in this manual shall be construed to invalidate any investigation, trial in which arraignment has been had, or other action begun prior to February 1, 1949."

"The maximum punishment for an offense committed prior to February 1, 1949, shall not exceed the applicable limit in effect at the time of the commission of such offense."

"This manual shall be in force and effect in the Army of the United States on and after February 1, 1949 with respect to all court-martial processes taken on or after February 1, 1949."
