Organized at Lynnfield by the efforts of the Hon. Henry Wilson, who afterwards became vice-president of the United States. The regiment arrived at Hall's Hill, Va., on October 13, 1861, and, encamping there, was engaged in perfecting its drill and discipline until March, 1862, when it commenced active service in the Peninsular Army. It served there in Martindale's (1st) Brigade, Morell's (1st) Division, Fitz John Porter's Corps. It was engaged in Porter's great battle at Gaines's Mill, where it was one of the last to yield its ground, holding its position so long that it lost several prisoners thereby. Its casualties at Gaines's Mill were 58 killed, 108 wounded, and 117 captured or missing; many of the latter were either killed or wounded. Colonel Gove, who commanded the Twenty-second in that battle, was killed, and Major Tilton was wounded and captured. More hard fighting followed immediately, at Malvern Hill, swelling its losses in the Seven Days Battle to 69 killed, 153 wounded, and 124 missing; total, 346. At Gettysburg, General Barnes commanded the division, Colonel Tilton, the brigade, and Lieutenant-Colonel Thomas Sherwin, the regiment; its casualties on that field were 8 killed, 27 wounded, and 1 missing, The regiment went into winter-quarters near Bealton, Va., building in addition to their huts, a neat chapel which was used by the men as a church and as a Lyceum; it was also used as a lodge room by Warren Army Lodge, No. 1, F.A.M. The Twenty-second, though small in numbers, sustained a heavy percentage of loss at the Wilderness and Spotsylvania, losing 121 in killed and wounded -- nearly half its strength.
