One Day on The Somme by Barry Cuttell. I bought this at the Thiepval Memorial shop about 10 years ago, I usually date them inside the cover but forgot for this one. Anyway, I love this book – brilliantly detailed, mapped and explained objective by objective. It looks, reads and feels like a work of love and spiral makes it so practical and easy to use. Always in the backpack and not heavy! No prizes for guessing tomorrow’s field book.
