This Regiment was organized at Augusta, Me., in October, 1862, to serve nine months, and on the 29th of October left that place for New York.

On the 31st of October they went into camp at East New York, and there remained until the 12th of January, 1863, when they embarked for New Orleans, La., arriving in that city on the 14th of February.

On the 26th of February they embarked on board the steamer Eastern Queen for Bonnet Carre, forth miles above New Orleans, and there were assigned to the 3d Brigade, 2d Division, under command of Gen. Nickerson. During their stay at that place, detachments from the regiment were engaged in active duties at different times and places.

On the 21st of May they were ordered to Port Hudson, where they remained through the whole siege of that place. They were constantly on duty from the time of the investment of Port Hudson until they started for home, and were often engaged with the enemy. They lost heavily from disease, not less than 184 men having died.

On the 24th of July they left Port Hudson for Maine, via Cairo, Ill., arriving on the 5th of August at Augusta, where the men were mustered out and discharged the U. S. service on the 25th of the same month, by Lieut. F. E. Crossman, 17th U. S. Infantry.
