At the time, millions of indigenous people were scattered across North America in hundreds of different tribes. Between 1622 and the late 19th century, a series of wars known as the American-Indian Wars took place between Indians and American settlers, mainly over land control.

Their widespread presence on the battlefields was documented by government photographers covering the war. Today, hundreds of photographs of dogs and cats and horses can be found among the Wor...

Horse and  camel-mounted troops  were used throughout the war, particularly in the desert campaigns, but on the  Western Front  cavalry charges became increasingly difficult as the fighting became deadlocked and trench warfare took over. Over the course of the twentieth century, the role of cavalry continued to change as combat became more mechanised.
