Most anthologies of WW1 poetry concentrate on the well-known poets such as Wilfred Owen, Siegfried Sassoon and Ivan Gurney. This book doesn't. Instead it looks mainly at the writings of the common Tommy in the trenches (who nevertheless must have been pretty literate). Other interesting poems are from the despised conscientious objectors which were often circulated on smuggled magazines.
The book takes a chronlogical approach and each section has a brief and useful summary of the major events that formed that time period which then also act as the themes for the sections.
Some of the poems are caustic, some humorous; all are poignant. It's fascinating to see such gems produced under such cataclysmic circumstances.
I can't recommend this book highly enough. You can dip into it; read whole sections, or read it from cover to cover.It's immensely enriching and ultimately uplifting to hear these voices from the past.
