General Adelbert Ames - he was governor of Mississippi during reconstruction.
Colonel of the 20th Maine 8/20/1862-5/20/1863
Ames, Adelbert, brigadier-general, was born in Rockland,
Me., Oct. 31, 1835. He was graduated at West Point in 1861,
and assigned to the 5th artillery. At the battle of Bull Run
he was wounded, and was brevetted for gallantry in that
action. He was present at the siege of Yorktown, and the
battles of Gaines, mill, Malvern hill, Fredericksburg,
Chancellorsville, Antietam, and Gettysburg, besides many minor
engagements in Virginia throughout the Civil war. Having been
brevetted colonel for gallantry, he commanded a brigade and at
times a division, in the Army of the Potomac in the operations
before Petersburg in 1864. Gallant conduct at the capture of
Fort Fisher in 1865 won for him the brevet of major-general of
volunteers, and, later, he was brevetted major-general, U. S.
A., for "gallant and meritorious conduct in the field during
the rebellion." After the war he was promoted to the full
rank of lieutenant-colonel in the regular army, and on July
15, 1868, was appointed temporary governor of Mississippi, his
authority being extended later to include the 4th military
district. In 1870 he was elected United States senator, a
position which he resigned three years later to accept the
office of governor. This office he resigned in 1876, removing
to New York, and later to Lowell, Mass. On June 20, 1898, he
was appointed brigadier-general of volunteers, in which
capacity he served throughout the war with Spain.
