The greatest defeat ever experienced by the British Army was that in the Mountain Passes of Afghanistan. Angus Cameron, the hero of this book, having been captured by the friendly Afghans, was compelled to be a witness of the calamity. His whole story is an intensely interesting one, from his boyhood in Persia; his employment under the government at Herat; through the defense of that town against the Persians; to Cabul, where he shared in all the events which ended in the awful march through the Passes from which but one man escaped. Angus is always at the point of danger, and whether in battle or in hazardous expeditions shows how much a brave youth, full of resources, can do, even with so treacherous a foe. His dangers and adventures are thrilling, and his escapes marvelous.
