Dooly W. Great Weapons of World War I

Walker, 1969. — 430 p.THE FIRST WORLD WAR was a transition in mammoth conflict between the Civil War and World War II. Some weapons, familiar to General Grant and General Lee, reached their ultimate in the appalling slaughter "over there." Others, just introduced, proved the mightiest tools of the next global clash.
The first conflict was bad enough. Fifty years of nature's balm have not erased its physical ravages from the face of Europe. Apart from the structures that were destroyed, forests were leveled, and even the ground was affected at scenes of massive battles. In some sections of the old Western Front where the earth was churned with mixtures of high explosives and chemicals during repeated bombardments, the soil remains unsuitable for agriculture. Signs affixed to rusting fences proclaim the areas still dangerous.
