It takes someone who really understands their subject to be able to write sparingly and still make the reader think. We all know the essence of this, the most horrid of wars. Gas, shells, machine guns, senseless offensives - we all have a vile image of trenches. Unlike other writers, Howard does not set out to alter this image. This book is an introduction to the military history of the war. The Eastern Front, Gallipoli, the war at sea are all covered and a truly global image emerges of powers pouring their lifeblood into a conflict that showed little sign of abating. This is the essence of the war. Howard shows how German victories on both the Eastern Front at the start of the war, and the Western Front at the end of the war, could not achieve the Clausewitzian victory of the Franco-Prussian war. He shows how dogged Allied tactical problem solving, especially in artillery support, and mobilisation of resources, especially in America, enabled the victors to press on to final victory. This was total war, this was grinding, grueling, starving, industrial war, won by deep pockets and sheer determination. This is the introduction to Strachan's in depth study. This is the book that anyone interested in the Twentieth Century should read. This is distilled historical thought.
