Wargames through the Ages was first published to fill a gap in literature of the hobby of wargaming. It was a one volume summary from the outbreak of the American Civil War and the concludes with the end of World War II in 1945. Between 1860 and 1945, the shape of warfare, armies, tactics and equipment underwent a wholesale change. In the same era, the map of Europe was redrawn and the machinations of world politics saw the introduction of military movements by land, sea and air on an international scale hitherto unconsidered. In 1861, the cavalry retained a still significant, if diminishing, role in the schemes of battle commanders; but by 1945 massive technological advances, culminating in the introduction of computerised planning had so altered the situation that a fundamentally new approach was necessitated as it is for the wargamer. The author has therefore considered at length the problem of formulating new rules, and the classification and assessment of armies and their conditions.
