Civil War Union Army Officer. He enlisted in the 10th Connecticut Volunteer Infantry, and recieved a commission of 2nd Lieutenant on November 27, 1861. He rose in rank after that, becoming a 1st Lieutenant on January 1, 1862, then regimental Adjutant on August 5, 1862. In the Union assaults on Confederate positions at Morris Island, Soutn Carolina in July 1863, he was capture and imprisoned in Columbia, South Carolina. He remained a captive of the Confederate forces until April 1864, when he was paroled. The attrition among the officers of the 10th Connecticut due to the constant campaigning in the war facilitated his promotion from Adjutant to Major on September 24, 1864. He would serve at that rank for less then a month, being killed in action in the Union army operations at Darbytown Road, near Richmond, Virginia on October 13th. His death was lamented by not only his own regiment, but by brigade commander Colonel Harris Plaisted of the 11th Maine Volunteer Infantry, who wrote in his official report "Major Camp was killed: he fell among the foremost of his comrades and within a few yards of the enemy's line. Our cause cannot boast of a nobler martyr than Henry W. Camp. His name will be recorded with those of Ellsworth and Winthrop, youthful heroes who have given their lives for their country". Soon after the end of the conflict the 10th Connecticut's chaplain, Reverend H. Clay Trumbull, published a biography of Major Camp entitled "The Knightly Soldier".
