Organized at Lynnfield, Mass., and arrived at Washington August 30, 1861. It was stationed in Maryland, along the Upper Potomac, until March, 1862, when it was assigned to Dana's (3d) Brigade, Sedgwick's (2d) Division, Second Corps, with which command it then moved to the Peninsula. It was hotly engaged at Glendale, its losses there and at Malvern Hill, amounting to 19 killed, 84 wounded, and 42 missing. At Glendale, Colonel Hinks was wounded, and Major Henry J. Howe was killed. The regiment was engaged at Antietam, in Sedgwick's contest in the woods around the Dunker Church, losing there 8 killed, 108 wounded, and 30 missing; Colonel Hinks was again severely wounded. The loss at Fredericksburg was 14 killed, 83 wounded, and 8 missing. In this engagement, the Nineteenth -- under Captain Weymouth--crossed the river in boats, together with the Seventh Michigan, acting as a forlorn hope. The boats crossed in the face of the enemy's fire from the opposite bank, which had hitherto prevented the laying of the pontoons. The Nineteenth, under Colonel Devereux, distinguished itself at Gettysburg, winning especial mention in the histories of that battle; its casualties there were 9 killed, 61 wounded, and 7 missing, out of 141 engaged. During the Wilderness campaign it was in Webb's (1st) Brigade, Gibbon's (2d) Division, and fought in all the subsequent battles of the Second Corps.
