Lincoln promoted Grant to Lieutenant General

Lincoln was concerned that Grant might be considering a presidential candidacy in 1864. He arranged for an intermediary to inquire into Grant's political intentions, and once assured that he had none, Lincoln promoted Grant to the newly revived rank of Lieutenant General, a rank which had been unoccupied since George Washington. Authorization for such a promotion "with the advice and consent of the Senate" was provided by a new bill which Lincoln signed the same day he submitted Grant's name to the Senate. His nomination was confirmed by the Senate on March 2, 1864.
