For a really different perspective try John Terraine’s DOUGLAS HAIG: THE EDUCATED SOLDIER and/or Terraine’s shorter THE WESTERN FRONT 1914-1918. In both he defends the Brit from the usual comic book depiction as the butcher of the Western Front and argues that Haig was destined for victory while Napoleon was destined for defeat (citing the nature and abilities of both men).
For the Eastern Front others have recommended Alexander Solzhenitsyn’s AUGUST 1914. I love Solzhenitsyn’s philosophy of history and how certain short time periods are “knots” of incredible events and change such as another knot in November of 1916 (lead-up events to the October 1917 Revolution). In AUGUST 1914 Solzhenitsyn writes of a prewar schoolboy calling out to the elderly Leo Tolstoy and relates their reflections on philosophy and other exchanges of Russian home front thinking. It is not just the military maneuvers and the epic battle of Tannenberg. It is written like a novel but it is based upon true narratives and accounts that Solzhenitsyn collected.
In CANCER WARD Solzhenitsyn hit the top of his craft and the great Bethell and Burg translation makes the Engish version an easy read for an AS lengthy book. It is largely an autobiographical experience but goes again into the philosophy of life itself. I think it is his greatest work.
Can think of no 20th Century author that had a better understanding of history, human nature and the inevitable admixture that led to world tragedy. Solzhenitsyn in August 1914 painfully and accurately recorded the why and the actual events that doomed Russia between 1900-1917. Cancer Ward examines that the decadence and decline of Russia after 1920 did not happen in a vacuum. It demonstrated how the worst aspects of human nature, which are always present, were actually encouraged and celebrated in a decadent destructive frenzy. Solshenitsyn, like all great writers, had a universal perspective. Like Shakespeare his understanding of human nature, psychology and events transcends his beloved Russia and is applicable to all. Western readers would do well to reread Cancer Ward. Intelligent readers would recognize themselves and current times.It would be readily apparent that history is not a static,dead concept, but recurs because human nature does not change, and when a society surrenders to its baser instincts, the outcomes are very predictable. Solzhenitsyn was a very spiritual man. He understood the concept of “original sin” and that if man to be “saved” (even in this realm) he needed to experience a transcendence that each generation or each culture needed to achieve in their time.
