Twenty-First Regiment Infantry

This Regiment was organized at Augusta, Me., Oct. 1th, 1862, to serve nine months, and left the State on the 21st.

Arriving at Jersey City, they were ordered to report to Major General N. P. Banks, Commanding Department of the Gulf, and were quartered at East New York, where they remained two months, and then proceeded to New Orleans, arriving in that city on the 1st day of February, 1863.

They immediately proceeded to Baton Rouge and were assigned to the 1st Brigade, 1st Division, 19th Army Corps.

At Baton Rouge they were occupied in doing pictet duty and in protecting the city from repeated attacks of guerillal.

On the 14th of March they were among the first to approach the works of Port Hudson to co-operate with the fleet which passed those works on that memorable night.

Again on the 21st of May they met the enemy on Port Hudson plains, where they fought against superior numbers.

They participated in the siege of Port Hudson, and in the assaults on the 27th of May and on the 14th of June, losing in these engagements, 88 men killed and wounded.

During this siege their term of service had expired, but they volunteered to remain until the taking of the place was accomplished, which was done on the 9th of July, 1863, when they were assigned to the 2d brigade of the post forces.

On the 25th of July they embarked for Maine, and arrived at Augusta on the 7th of August, where they were mustered out and discharged the U. S. service Aug. 27th, by Lieut. F. E. Crossman, 17th U. S. Infantry.
