For soldiers in the Great War, going over the top was a comparatively rare event; much more frequently, they were bored and lonely and missing their families at home. Needing an outlet for their affection, many found it in the animal kingdom. Tommy's Ark looks at the war through the eyes of the soldiers who were there, and examines their relationship with a strange and unexpected range of animal life, from horses, dogs and cats to monkeys and birds - even in one case a golden eagle. Animals became mascots - some Welsh battalions had goats as mascots, some of the Scots had donkeys. And then there were the animals and insects that excited curiosity amongst men drawn into the army from the industrial heartlands of Britain, men who had little knowledge of, let alone daily contact with, wildlife. Civilians turned soldiers observed the natural world around them, from the smallest woodlouse to voles, mice and larger animals such as deer and rabbit. Richard van Emden explores his subject far more radically than previous attempts, revealing how, for example, a lemur was taken on combat missions in the air, a lion was allowed to pad down the front line trenches and how a monkey lost its leg during the fighting at Delville Wood on the Somme. Illustrated with more than sixty previously unseen or rarely published photographs, drawn mainly from the author's own extraordinary collection.

Conventional histories of the Great War have tended to focus on the terrible attritional battles of Ypres, of Arras and of the Somme. What they do not tell us is what life was like for the ordinary soldier, what mattered to him, and how he survived, both physically and mentally. Now for the first time, one of Britain's leading military historians, Richard van Emden tells the story of the Great War exclusively through the words and images of soldiers on the ground. In Tommy's War, he gathers some of the very best first-hand material written about the War, some of it published at the time and forgotten, some of it previously unpublished, but all of it wonderfully descriptive and immediate, and often wickedly funny. Tommy humour, frequently very dark, played a vital part in men's mental survival, particularly in times of great stress. Until now its critical role in victory has been overlooked. Richard van Emden restores the balance, giving weight to the soldiers' natural inclination to laugh during their darkest moments. Illustrating these eyewitness accounts with soldiers' own photographs taken on privately owned cameras, often tiny Vest Pocket Kodaks – the smart phones of their day – van Emden has created an entirely new and fresh history of the Great War, giving us a glimpse of 'Tommy Atkins' as he has never been seen before.
