Charles Russell Lowell, Jr., the older brother of James Jackson Lowell, was an aide-de-camp to Major General George B. McClellan in the Union Army. He was with McClellan at both the Seven Days Battle (also known as the Peninsula Campaign) and the Battle of Antietam. He died later in the war on 20 October 1864 from wounds received at the Battle of Cedar Creek.
Like his brother, Charles Russell Lowell, Jr., was remembered in a eulogy given by Cyrus A. Bartol at West Church, Boston. The tribute was titled The Purchase by Blood and began, "That is to say, the blood has in it a certain price or power to purchase. Any thing in the world is worth what you can buy with it; and blood is incomparable treasure, by this rule."
