The burden of the Great War was not shouldered by soldiers alone: the tasks, the camaraderie, the day-to-day life and the devastation were all shared with the animals that accompanied the forces abroad.

The horses that took part in the last cavalry charges or hauled heavy guns are the most famous examples, but were far from alone: pigeons carried vital messages, dogs sniffed out wounded soldiers, camels were used as beasts of burden in the desert, and even ships' cats and baby orang-utans had their parts to play.

From noted historian Neil R. Storey, this book looks at all the practical ways in which animals were essential to the war effort, but is equally interested in their roles as companions, mascots and morale boosters - on land, in the air and at sea.
