They remained at Arlington Heights until the 3d of November, when they were ordered to Fortress Monroe, Va., where they arrived on the 7th, thence proceeded to Newport News, and there remained until the 2d of December.

On the 4th of December they left for New Orleans, arriving in that city on the 15th, and immediately proceeded to Baton Rouger, which they occupied on the 17th. On the 31st they were assigned to the 1st Brigade of Grover's Division. They remained at Baton Rouge until the 13th of March, 1863, when they took part in a reconnoissance to the rear of Port Hudson, after which they returned to Monticello Bayou.

On the 26th of March they joined the expedition up the Atchafalya Lake, and on the 13th of April safely landed at "Irish Bend," where, after crossing the Bayou Teche, they encamped for the night.

Early on the morning of the 14th they moved in the direction of Franklin, met the enemy, and after a spirited engagement, drove them from the field.

On the 6th of May they moved towardsPort Hudson, arriving at that place on the 1st of June, and on the 9th participated in an assault on the enemy's works, but were compelled to fall back and were soon after withdrawn, returning to their former duties.

On the 14th of June they again participated in an assault on the enemy's works, which, however, was unsuccessful, and after dark they were withdrawn and returned to the position they occupied before the battle.

After the surrender of Port Hudson on the 8th of July, they were quartered inside the works, and there remained until the 24th, when they started for Maine, passing up the Mississippi River by boat to Cairo, then by rail to Bangor, where they arrived on the 8th of August, and were mustered out and discharged the U. S. service on the 15th of the same month by Lieut. F. E. Crossman, 17th U. S. Infantry.
