One of the most interesting books on the Great War I've read recently. Cook's research into a hitherto neglected area of the First World War will open your eyes to both the extent and horror of chemical warfare and the amazing efforts made to minimize the effects. Usually mentioned merely in passing in many well regarded histories of WWI, the in depth treatment of gas warfare in all of its aspects brings a whole different view of the First World War battlefield.
Five stars for actually providing something new and original!
