The first attack on Fort Fisher, during the American Civil War, failed utterly; the second succeeded magnificently. The commanders of the latter learned from the experience of the former; the lessons of both attempts were valuable for the great amphibious operations of the mid-twentieth century, and they remain instructive today.
