The Twelfth Regiment Connecticut Volunteers was recruited at Camp Lyon, Hartford, early in the year 1862, and left for Ship Island, Mississippi Sound, February 24th, 1862, with ten hundred and eight (1008) men. This fine regiment was known as the " Charter Oak Regiment" was commanded by Colonel Henry C. Deming, and was attached to Major General Benjamin F. Butler s Division. The men were armed with Sharps and Windsor rifles.

The regiment was stationed in or near New Orleans, as a portion of the army of the Department of the Gulf, during the year 1862, and a part of 1863. Colonel Henry C. Deming was for the greater part of the time engaged in performing the duties of a civic officer, in consequence of which the command devolved upon Lieut. Colonel Ledyard Colburn. On the 31st of January, 1863, Colonel Deming resigned, and Lieut. Colonel Colburn was promoted to the Colonelcy.

On the 27th of October, 1862, the regiment participated in the battle of Georgia Landing, near Labadierville, La., and sustained a loss of nineteen (19) men in killed, wounded and missing.

On the 27th of March, 1863, Company "A" thirty-five men, embarked on board the gun boat Diana, in connection with one company from the 160th New York, to make a reconnoissance into Grand Lake to the mouth of theTeche. Returning through Atchafalaya, they were fired upon near Pattersonville, and after a severe fight of an hour, were all captured. They are reported to have fought with the greatest gallantry, and only surrendered when surrounded by greatly superior numbers, after the boat had been disabled.

On the 9th of April following, the regiment started on an expedition against the enemy, and left Brashear City for Berwick, where it remained until the llth, when it marched to a point one mile above Pattersonville. On the 13th, soon after daylight the regiment was formed in support of the 21st Indiana Battery, which opened upon the enemy s fortifications and gunboat "Diana" which had taken position upon the left.

After the silencing and withdrawal of the "Diana" the regiment was advanced to the front of the enemy s works, and successively during the day supported Carruth's, Mack's, Duryea's and Bainbridge's batteries. Companies E, F, and G, were advanced as skirmishers, and approached to speaking distance of the enemy s entrenchments, and were actively engaged during the whole afternoon, with very apparent effect. The object of the expedition being gained, the regiment was marched to Opelousas, where it arrived on the evening of the 20th.

Lieut. Colonel Peck speaks in the highest terms of the conduct of the regiment as a whole, and mentions the names of Major George N. Lewis, and Captains Granniss and Brennan, as deserving of great praise.

The regiment continued in the Department of the Gulf, attached to the army under General Banks in Louisiana, and bore a conspicuous part in the siege of Port Hudson. It was engaged in that siege from- May 25th to July 9th, 18G3, and sustained an aggregate loss of one hundred and eight (108) officers and men.

In closing his report of the siege of Port Hudson, Lieut. Colonel Peck writes: "On the night of the 8th of July, for the first time since we advanced to the front, we were permitted to sleep without an uninterrupted accompaniment of artillery and musketry. On the 9th, with martial music and flying colors, we marched into Port Hudson."

In the Spring of 1864, more than three-quarters of the regiment re-enlisted as veterans, and returned to Connecticut on furlough. On the 8th of May, it returned to New Orleans, La., and remained in that vicinity until July 6th, 1864, when it embarked for Fort Monroe, Va., and finally, on the 7th of August, joined the army under General Sheridan, in the Shenandoah Valley. At the battle of Opequan (Winchester), September 19th, 1864, the regiment lost seventy-one (71) officers and men, killed and wounded; among them Lieut. Colonel Frank H. Peck, commanding, who was struck by a piece of shell and mortally wounded, while gallantly leading the regiment into action ; also there were killed 1st Lieutenants William S. Buckley and George W. Steadman, brave and efficient officers.

On the 22d of September was fought the battle of Fisher s Hill, and although the Twelfth occupied a more important position throughout the engagement, it most happily sustained no loss.

On the l0th of October, Lieut. Colonel George N. Lewis (promoted from Major, vice Peck killed in action) reported for duty, who until that time had been absent in Connecticut, from the effect of a wound received at Port Hudson, in May, 1863, and assumed the command.

The regiment, under Colonel Lewis, participated in the battle of Cedar Creek, Va., and sustained a total loss of one hundred and seventy (170) officers and men. It was in this engagement that Captain John P. Lowell and 2d Lieutenants Horace E. Phelps and George M. Benton, received their death wounds, the two former dying on the field, the latter a few days later in hospital. All are mentioned as brave and meritorious officers, who were loved and respected by their comrades.

The severe losses sustained by the command, and the near expiration of the term of service of such as did not re-enlist, necessitated the consolidation of the regiment. And accordingly, under provision of Special Order No. 45, Head Quarters, Middle Military Division, of November 26th, 1864, the 12th Battalion Connecticut Vet. Vol. Infantry was organized, and continued to serve in Virginia, under the command of Lieut. Colonel Lewis, until its final muster-out, August 12th, 1865.

In January and February, 1864, four hundred and thirty-six (436) men re-enlisted as veterans for a term of three years, and subsequent to the organization of the regiment about four hundred (400) new recruits joined its ranks.

The regiment participated in the following general ENGAGEMENTS.

Georgia Landing, La., October 27th, 1862. Loss in killed, 3 enlisted men; wounded, 15 enlisted men; taken prisoner, 1 commissioned officer. Total loss, 19.
