The Twenty-fifth Regiment Connecticut Volunteers was recruited in Hartford and Tolland counties, and rendezvoused at Camp Halleck, Hartford. On the 14th of November, 1862, the regiment left Hartford for Camp Buckingham, Centerville, L. L, its numerical strength being eight hundred and eleven (811), It formed a part of General Banks division, and after a short stay at Centerville, embarked for New Orleans, La. No official report of its movements prior to the month of March, 1863, has been received by the Adjutant General.

On the 13th of March the regiment, together with the whole army, advanced toward Port Hudson, on the Bayou Sara and Clinton roads. That night bivouacked about eight miles from Baton Rouge. On the 14th, advanced some five miles further and there took up a position, being but a short distance from the enemy's works. The object of the expedition (attracting the attention of the enemy while the Union fleet passed the batteries, and the masking of a movement on the Clinton road by another portion of the army having been accomplished, the entire army fell back in a most severe storm, which, while it seriously affected the comfort of our own forces, frustrated the design of the enemy to attack our columns.

The sufferings of the members of the 25th regiment are reported as almost unendurable. On the 16th the regiment bivouacked about eight miles above Baton Rouge in advance of the army. On the 28th of March the regiment embarked for Donaldsonville. On the 31st the regiment started for Thibodeaux where it arrived on the 2d of April, thence by rail to Bayou Boeuf, and on the 9th marched to Brashear City where it remained until the 12th, when it commenced its skirmishing with the enemy. On the morning of the 14th the regiment was thrown to the front and right to skirmish and cover the advance of the main body, and shortly after began the battle of Irish Bend, in which the regiment sustained a total loss of ninety-six (96), while only one (1) of the whole was reported missing, all the others being either killed or wounded. The regiment was commanded by Colonel Bissell in person, and behaved with all the courage and steadiness of veterans. It was in this battle that Second Lieutenant Daniel P. Dewey, of Co. A, a brave and gallant young officer, laid down his life. He was loved and respected for his bravery, fidelity and soldierly qualities, and his loss is severely felt by his comrades.

From the date of the battle of Irish Bend, until May 25th, the regiment was engaged in marches, and was for the most part without communication with its baggage; at one time officers and men being without a change of clothing for a month.

On the 24th of May commenced the investment of the works before Port Hudson, this regiment being assigned the centre. The regiment was under the command of Major McManus during the battle, Colonel Bissell being absent and quite ill.

That the regiment bore a conspicuous part in this battle is fully attested in the official reports. Some of its men were without rations for more than forty hours, and yet they performed their duties without a murmur. The regiment sustained an aggregate loss of twenty-eight (28) officers and men.

Again on the 14th and 15th of June the regiment participated in another attack upon the enemy s works, and sustained a loss of eighteen (18) killed, wounded and missing. After such a long and tedious campaign the regiment became greatly reduced, and on the morning of the 26th of June, Adjutant Ward reported but one hundred and forty (140) men fit for duty. By the bravery displayed on the field of battle, and the patient endurance on the many long and arduous marches, the regiment has won for itself a high and lasting reputation. It continued in active service in the Department of the Gulf until the expiration of its term of service, and was finally mustered out August 26, 1863.
