Though many collectors have a working knowledge of these entrenching tools and bayonets, few know all the interesting details of these colorful tools and blades. Forty years of collecting and ten years of intensive research have produced these thorough, accurate and fully documented studies.A fascinating look at the development and issuance of these often forgotten items. The book is divided into four major chapters. The first is a needed albeit brief history of the “serious disconnect between the recognition of the value of entrenchments and the availability of portable, appropriate, and accessible tools with which the soldier could construct hasty entrenchments.” The second chapter is a review of the important Boards of Officers that recommended various elements for field trial. The third chapter, profusely illustrated, details single functioning tools. Chapter four addressed multi-function tools. A detailed, well rounded bibliography rounds out the book. Excellent!
