DESCRIPTIONS ABOUND of military actions in which cavalry have played a major part. Tactics, the names of regiments, the men involved, their arms and uniforms - all these are covered in detail in countless books, films and articles. Yet little is said about the horse, without whom very little would have been achieved in the military sphere, in any era. This may be because, with rare exceptions, military historians are not horsemen or women, and the latter are seldom military historians. Ann Hyland is both of these things. In this latest volume in her acclaimed Warhorse series, she gives a comprehensive account of the horse in war from the beginning of the 17th century to the end of the American Civil War. The modern era saw a period of tremendous transition for the warhorse which began with the change from the accepted, but erroneous, concept of the medieval Great Horse, whose body mass was not always so great, to the better bred, more mobile, speedier animal that evolved from the seventeenth to the nineteenth century. Many changes hinged on four breeds of horse: the Arabian, the Barb, the Andalusian, and the English Thoroughbred.All influenced the cavalry of the era, particularly when crossed onto each country's native mares. Using many eyewitness accounts by those who took part in these and other campaigns, as well as official sources, Ann Hyland gives us a moving picture of the sacrifices demanded of - and made by, with so little complaint - this most noble of creatures. In the midst of dreadful carnage and in often appalling conditions, we catch glimpses of the bond which existed between these horses of war and the men who rode and cared for them. The Warhorse in the Modern Era is a fascinating and readable book which will appeal to both military history buffs and horse lovers alike.
