Battle of Gettysburg
The regiment lost 10 killed, 23 wounded and 4 missing at Gettysburg out of 75 men - almost 50% casualties. It was only three companies strong after its losses at Chancellorsville. When Lt. Col. Mervin fell, Major James H. Coburn took command of the regiment.
From the regiment's monument at Gettysburg: "The 27th Regt. Conn. Vols. commanded by Lieut. Colonel Henry C. Merwin and forming a part of the 4th Brigade, 1st Division, 2nd Corps charged over this ground the afternoon of July 2, 1863."
"The 4th Brigade forced the enemy from the Wheat Field and beyond the woods in front where the advanced position of the 27th Regt. is indicated by a tablet on the crest of the ledge. On this spot Lieut. Col. Merwin was killed while gallantly leading his command of 75 officers and men 38 of whom were killed or wounded in the charge. Eight companies of the regt. captured at Chancellorsville were still prisoners of war."
"Capt. Jedediah Chapman Jr. was also killed in the charge wile commanding a company organized from detached members of the eight companies taken prisoner at Chancellorsville."
