He was wounded in action six times, slightly at Cold Harbor on June 3, 1864, and Monocacy on July 9, 1864, and was hit four times at Cedar Creek on October 19, 1864. Due to his wounds and other medical reasons, he resigned his commission on December 17, 1864 and was mustered out of the volunteer service. His departure from the regiment, was "greatly regretted by the officers and men, and their personal regard and regret found expression in a highly complimentary parting testimonial, signed by all but two of the officers of the regiment. In this paper they also requested Colonel Henry to carry home with him and present to the Legislature of Vermont the tattered colors of the regiment, under which no less than twenty of the color guard had been killed or wounded."
