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. Before he died he did at least two things that he desired. One may seem much greater than the other; but he would not have shrunk from naming them together. He saw the end of an empire that was the nightmare of the nations; but I believe it pleased him almost as much that he had been able, often in the intervals of bitter warfare and by the aid of a brilliant memory, to put together these pages on the history, so necessary and so strangely neglected, of the great democracy which he never patronised, which he not only loved but honoured.
