A slight change in organization took place under Hardee’s tactics; instead of four lieutenants to a company, there were only two. Consequently few new men were elected to fill vacancies until the regiment had adjusted itself to the new régime. The officers of the regiment at the great Concord encampment, besides Col. Cowdin, were: Lieutenant Colonel, Isaac S. Burrell (postmaster of Roxbury, and later City Marshal); Major, Isaac F. Shephard. The captains commanding companies were: 1st, Thomas L. D. Perkins (proprietor of a smoke-house); 3d, Henry A. Snow (treasurer of a bleachery); 6th, Edward Pearl; 7th, Walter S. Sampson (a mason and builder); 8th, Clark B. Baldwin (a merchant); 9th, Arthur Dexter; and 10th, Joshua Jenkins. With the Civil War less than two years off, it is well to look ahead and see how many of these militiamen rendered service in the hour of their country’s need. Of the Colonel we have already spoken. The Lieutenant Colonel commanded the 42d Regiment in 1862, and again in 1864, as we shall see. The Major presently removed to Missouri for business reasons, where he served with Nathaniel Lyon, and ultimately commanded the 51st U. S. Colored Infantry, and was promoted to be Brigadier General. Four of the seven captains went to war. Capts. Snow and Pearl served three months each at the beginning of the regiment’s three years of service, and then received their discharges. Capt. Sampson took his company into the 6th Regiment, and led them thru Baltimore on April 19, 1862, under deadly fire from the rioters. Later he served as Captain in the 22d Infantry during the Peninsular campaign, commanding that regiment at Gaines Mill. Capt. Baldwin remained in Col. Cowdin’s regiment when his company transferred themselves to the new 4th Battalion of Rifles and ultimately to the 13th Regiment; and became commander of a new 4th Company, and from 1862 to 1864 was Lieutenant Colonel of the regiment. Baldwin was a most profane man, and during the ensuing campaign stragglers could identify their regiment from a distance by the sound of his swearing. When Baldwin was made prisoner at the Wilderness, his captors marvelled at his vocabulary; and came up to his tent in successive reliefs to listen. Once a youthful fifer who had been caught by the then Lieutenant Colonel straggling, was punished by having a log loaded on his shoulder as he marched. This lad has put on record, that regulations provided for “a field officer at the head of a regiment and a mule at the rear”; and that Col. Baldwin was deemed well-qualified for either end of the column. But the testimony is confessedly biassed.
