This is a two-tape set, and is the first half of a two-set series of tapes on World War I. (The second half is called 1914-1918 The Crucible).
Together, they are an excellent review of World War I -- its origins, the soldiers who fought it, the big battles and strategies, the impact on society, and the aftermath. It uses classic film footage, archive photos, and expert commentary to weave together the complex story of the war.
This first half, naturally, explores the origins of war and traces the war through the first couple of years of warfare, when the combatants slowly came to realize they were locked in a tragic stalemate that was devastating to all concerned.
This is big, lavish and authoritative; a great introduction to this vital bit of history.
