My Dear Lads,  
The present story was written and published a few months, only, after the termination of the Franco-German war. At that time the plan--which I have since carried out in The Young Buglers, Cornet of Horse, and In Times of Peril, and which I hope to continue, in further volumes--of giving, under the guise of historical tales, full and accurate accounts of all the leading events of great wars, had not occurred to me. My object was only to represent one phase of the struggle--the action of the bodies of volunteer troops known as franc tireurs.
 
The story is laid in France and is, therefore, written from the French point of view. The names, places, and dates have been changed; but circumstances and incidents are true. There were a good many English among the franc tireurs, and boys of from fifteen to sixteen were by no means uncommon in their ranks. Having been abroad during the whole of the war, I saw a good deal of these irregulars, and had several intimate friends amongst them. Upon the whole, these corps did much less service to the cause of France than might have been reasonably expected. They were too often badly led, and were sometimes absolutely worse than useless.
 
But there were brilliant exceptions, and very many of those daring actions were performed which--while requiring heroism and courage of the highest kind--are unknown to the world in general, and find no place in history. Many of the occurrences in this tale are related, almost in the words in which they were described to me, by those who took part in them; and nearly every fact and circumstance actually occurred, according to my own knowledge. Without aspiring to the rank of a history, however slight, the story will give you a fair idea of what the life of the franc tireurs was, and of what some of them actually went through, suffered, and performed.
 
Yours sincerely,
 
The Author.
