Twenty-fourth Infantry.--Col., George M. Atwood; Lieut. Cols., Charles T. Bean, Eben Hutchinson; Majs., Eben Hutchinson, William Holbrook.  This regiment was mustered into the U. S. service at Augusta, Oct. 16, 1862, to serve for nine months.  On the 29th it left for New York and reported to Maj. Gen. Banks.  The regiment was detained at East New York by sickness until Jan. 12, 1863, when it embarked for New Orleans, arriving there Feb. 14.  On the 26th it was ordered to Bonnet Carre, 40 miles above New Orleans, and was there assigned to the 3d brigade, 2nd division, under command of Gen. Nickerson.

While at this place details from the regiment were variously engaged in active duties at different times and places.  On May 21, it was ordered to Port Hudson and participated in the entire siege of that stronghold, including the desperate assaults of May 27 and June 14, but suffered few casualties.

The southern climate, however, worked havoc in their ranks, as they lost 184 men from disease and nearly 100 more were discharged for disability.  Of the 900 men who went out with the regiment, 570 returned.  It left Port Hudson for Maine, via Cairo, Ill., July 24, arrived at Augusta on Aug. 6, and was mustered out on the 25th of the same month, after a term of service of nearly one year.  None was killed in battle or died of wounds.
