The author of this book, my brother, died in a French military hospital of the effects of exposure in the last fierce fighting that broke the Prussian power over Christendom; fighting for which he had volunteered after being invalided home. Any notes I can jot down about him must necessarily seem jerky and incongruous; for in such a relation memory is a medley of generalisation and detail, not to be uttered in words. One thing at least may fitly be said here.
