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.
In addition to this, every northward movement of the Confederate Army after January, 1863, was accompanied by a diversionary operation of Mosby's command, sometimes tactically insignificant but always contributing, during the critical time of the operation, to the uncertainty of Union intelligence. Likewise, every movement to the south of the Army of the Potomac was hara.s.sed from behind.
It may also be noted that Sheridan, quite capable of dealing with the menace of Stuart, proved helpless against the Mosby nuisance, although, until they were wiped out, Blazer's Scouts were the most efficient anti-Mosby outfit ever employed. In spite of everything that was done against them, however, Mosby's Rangers stayed in business longer than Lee's army, and when they finally surrendered, it was not because they, themselves, had been defeated, but because the war had been literally jerked out from under them.
Mosby made the cavalry a formidable amalgamation of fire power and mobility and his influence on military history was felt directly, and survived him by many years. In his last days, while living in Washington, the old Confederate guerrilla had a youthful friend, a young cavalry lieutenant fresh from West Point, to whom he enjoyed telling the stories of his raids and battles and to whom he preached his gospel of fire and mobility. This young disciple of Mosby's old age was to make that gospel his own, and to practice it, later, with great success. The name of this young officer was George S. Patton, Jr.--H. Beam Piper
Jeb Stuart left John Singleton Mosby behind Northern lines "to look after loyal Confederate people." But before the war was over, Mosby did a lot more than that....
