So Mosby returned to Fauquier County to take the parole. For him, the fighting was over, but he was soon to discover that the war was not. At that time, Edwin M. Stanton was making frantic efforts to inculpate as many prominent Confederates as possible in the Booth conspiracy, and Mosby's name was suggested as a worthy addition to Stanton's long and fantastic list of alleged conspirators. A witness was produced to testify that Mosby had been in Washington on the night of the assassination, April 14. At that time, Stanton was able to produce a witness to almost anything he wanted to establish. Fortunately, Mosby had an alibi; at the time in question, he had been at Hancock's headquarters, discussing armistice terms; even Stanton couldn't get around that. However, he was subjected to considerable petty persecution, and once he was flung into jail without charge and held incommunicado. His wife went to Washington to plead his case before President Johnson, who treated her with a great deal less than courtesy, and then before General Grant, who promptly gave her a written order for her husband's release. Then, in 1868, he did something which would have been social and political suicide for any Southerner with a less imposing war record. He supported Ulysses S. Grant for President. It was about as unexpected as any act in an extremely unconventional career, and, as usual, he had a well-reasoned purpose. Grant, he argued, was a professional soldier, not a politician. His enmity toward the South had been confined to the battlefield and had ended with the war. He had proven his magnanimity to the defeated enemy, and as President, he could be trusted to show fairness and clemency to the South. While Virginia had not voted in the election of 1868, there is no question that Mosby's declaration of support helped Grant, and Grant was grateful, inviting Mosby to the White House after his inauguration and later appointing him to the United States consulate at Hong Kong. After the expiration of his consular service, Mosby resumed his law practice, eventually taking up residence in Washington. He found time to write several books--war reminiscences and memoirs, and a volume in vindication of his former commander, Jeb Stuart, on the Confederate cavalry in the Gettysburg campaign. He died in Washington, at the age of eighty-three, in 1916. The really important part of John Mosby's career, of course, was the two years and three months, from January, 1863, to April, 1865, in which he held independent command. With his tiny force--it never exceeded 500 men--he had compelled the Union army to employ at least one and often as high as three brigades to guard against his depredations, and these men, held in the rear, were as much out of the war proper as though they had been penned up in Andersonville or Libby Prison.
