The Twentieth Connecticut Volunteer Infantry was originally recruited in Hartford, New Haven, and Middlesex counties, rendezvoused at New Haven, and started for Washington September 11, 1862, with nine hundred and eighty-one (981) officers and men. It was assigned to the Army of the Potomac, and was attached to the 2d Brigade, 1st Division, 12th Army Corps.

On the 1st of April, 1863, the regiment was reported at Stafford Court House, Va. It broke camp on the 27th of April, and crossing .the Rappahannock river at Kelly s Ford, and the Rapidan at Germania Bridge, participated in the battle of Chancellorsville, May 1st, 2d and 3d, under command of Lieut. -Colonel Wooster, Colonel Ross being absent in command of the 2d Brigade.

The regiment behaved most gallantly during the engagement, and was highly complimented for its bravery. Second Lieutenant David N. Griffith of Co. F, was killed in the entrenchments by a musket shot in the forehead, and fell with his sword in his hand, a pattern of determined courage and bravery. Sergeant-Major John S. Root was killed by a shell at the barricades, in the early part of the action, and was noted for coolness and courage. The total loss of the regiment in this engagement was one hundred and ninety-seven (197) officers and men.

On the 3d of July, 1863, the regiment participated in the battle of Gettysburg, occupying the right of the line, as a part of the 1st Brigade, 1st Division, 12th Army Corps. On the night of the 2d of July, it lay in line of battle in a cornfield ready at an instant s notice. On the morning of the 3d a portion of the regiment was thrown forward as skirmishers, and for over five hours were unceasingly engaged with the enemy. The entire regiment was hotly engaged for more than six hours, and were constantly under arms during the nights of the 3d and 4th.

In his official report, dated August 1, 1863, Lieut-Colonel Wooster remarks: "Each officer and man then with me seemed intent only on doing his whole duty, cheerfully and promptly executing every order." Total loss during the engagement, twenty-eight (28).

In September, 1863, the regiment was transferred to the Army of the Cumberland, and proceeded by rail via Indianapolis, Louisville, and Nashville, to Bridgeport, Ala., where it arrived Oct. 3d. It was engaged in fatigue and picket duty, and participated in several slight skirmishes with the enemy during the autumn months. January 20, 1864, while a portion of the regiment was guarding Tracy City, Tenn., the place was attacked by rebel cavalry. The enemy were repulsed, and soon retired. Captain Andrew Upson, commanding the Post, was mortally wounded, and died Feb. 19. Private Russell, Co. B, was killed.

The regiment was changed to different localities during the winter and early spring, and on the l0th, of May, 1864, took part in the battle of Resaca, Ga. On the 19th of the same month it was engaged with the enemy at Cassville, Ga. Aggregate loss in the two engagements, twenty-one (21) killed, wounded and missing. Colonel Ross, in his report dated May 22, 1864, remarks, "the 20th Connecticut and 19th Michigan regiments, assisted by no other troops in line of battle, with fixed bayonets, assaulted and captured Cassville, and occupied it until the morning of the 20th of May."

The regiment continued its march with Sherman s army, and on the 20th of July participated in the battle of Peach Tree Creek, Ga. Lieut.-Colonel Buckingham, commanding the regiment, characterizes the battle as one of unusual severity, and quotes the language of captured rebel officers, who admitted that it was the most severe battle in which they had ever participated, and that their loss was far greater than ever before during the war. Col. Buckingham also speaks in the highest terms of the action of his command. It lost in this engagement fifty-five (55) in killed, wounded and missing, among the wounded six (6) commissioned officers.

Again on the 21st of July the Twentieth was engaged with the enemy near Atlanta, and sustained a total loss of- ten (10) men.

On the 25th of August the regiment marched to Turner s Ferry on the Chattahoochie river ; 27th it engaged in a skirmish with the enemy ; Sept. 2d it participated in the capture of Atlanta, Ga., in which vicinity it remained, furnishing large details for work on the fortifications about the city, until November 15th, when in conjunction with the left wing, Army of Georgia, it moved toward Savannah, Ga., which it reached on the l0th of December.

It was engaged in various siege operations against that place until the 21st, when the enemy having evacuated the city, the regiment entered with the 20th Corps, and took possession, capturing a large amount of artillery and other ordnance stores, and over 30,000 bales of cotton. On the 4th of January the regiment moved north and went into camp on Hardee's plantation, six miles from Savannah, where it remained until the 16th.

On the 16th it broke camp, and on the 17th marched to Hardeesville, ten miles, where it encamped and remained until the 29th of the same month. The regiment continued its march at intervals, until the 15th of March, when they encountered the enemy at Silver Run, N. C., and after a short engagement drove them from their line of works. The regiment s loss in this engagement was nineteen (19) officers and men.

On the 19th of the same month it participated in the battle of Bentonville, and fully sustained its reputation for courage and valor which it had already established on many a hard fought battle field.

During the campaign the regiment marched more than five hundred miles, destroyed miles of railroad track, built corduroy roads, captured and supplied itself with rations; endured wet, cold, hunger and fatigue without a murmur, and was finally mustered-out of service June 13, 1865, numbering five hundred and six (506) present and absent.
