Barrel of a Musket [EPUB ebook] 

A cautious and naturally scared, ordinary British soldier, Walker, is fighting in the wars against Napoleon Bonaparte’s French Army. He is joined throughout the battles by his friend Bob, who sometimes seems a crazy soldier. Bob seems to have a mystery life behind him. They are served loyally by their two horses, ‘;Boring’ and ‘;Scallibad the Great’.
