George L. Whitcomb was born around 1840 in Littleton, Massachusetts, to Vandola and Mary Whitcomb. His father was a farmer who owned $2,000 of real estate by 1850. He grew up and attended school in Littleton, and by the early 1860s, he was working as a farmer. In January 1861, he insisted that, “if the secession states have one jot of common sense they will not provoke an open collision with the Federal government in so unequal a contest as it must of course be.” If war broke out, he predicted, the South could expect only “defeat and disgrace.”
He enlisted in the Union army on July 23, 1862, and he mustered in as a corporal in Company E of the 33rd Massachusetts Infantry on August 5. The regiment took part in the Battle of Chancellorsville and the Battle of Gettysburg. He was wounded on October 29, 1863, and he died near Chattanooga, Tennessee, on November 12, 1863.
