|One Hundred and Twenty-third Illinois Infantry. — Col., James
Monroe; Lieut.-Col., Jonathan Biggs; Maj., James A. Connolly. This
regiment was organized at Mattoon, Cos. A, C, D, H, I and K being from
Coles county, B from Cumberland, E from Clark, F and G from Clark and
Crawford. It was mustered into service at Camp Terry, Mattoon, Sept. 6,
1862. On Sept. 19 the regiment was loaded into freight cars at Mattoon
and transported to Louisville, Ky., where it was at once put to work to
fortify the city against Bragg who was then advancing on it. On Oct. 8,
just 19 days after leaving Mattoon, the regiment was engaged in the
battle of Perryville, where it lost 36 killed and 180 wounded. Early in
March, 1863, it was attacked beyond Stone's river, while halted on
Breed's hill with arms stacked and ranks broken by a large cavalry
force, but forming under fire and repelling the attack, it waded Stone's
river, carrying off its wounded, and withdrew to Murfreesboro. On March
20 the brigade, including the regiment, was attacked and surrounded by
Morgan's cavalry, about 5000 strong, with 6 pieces of artillery, near
Milton, Tenn., about 12 miles out from Murfreesboro, but the enemy was
driven from the field, leaving his dead and wounded and 2 pieces of
artillery. In the affair at Hoover's gap in June the regiment lost
several in killed and wounded. In September it forded the river above
Chattanooga and led the advance of Crittenden's corps to Ringgold and
Tunnel Hill, Ga., constantly skirmishing during the three days' advance.
It was engaged in the battle of Chickamauga, taking its place in line
with the infantry of the 14th corps, to which it belonged. In October it
engaged in the battle at Farmington, Tenn., in which Wheeler was
severely punished and driven from the state. It participated throughout
the entire Atlanta campaign and then returned northward in pursuit of
Hood, continuing so engaged until Nov. 1, when it moved to Louisville,
Ky. In the spring of 1865 the regiment participated in the "Wilson Raid"
into Alabama and Georgia, and this marked the close of its career as an
organization. It was mustered out at Edgefield, Tenn., June 27, 1865.
