The World Goes to War

This episode picks up as Germany's rapid advance slows and trenches begin to dominate the Western Front. We'll track the early battles that turned a fast war into a brutal deadlock: the Marne, the race to the sea, and the rise of trench warfare. We also look east, where Russia moved faster than anyone expected and forced Germany to divert troops. Meanwhile, new players entered the war, Italy switched sides, the Ottomans joined in, and the entire Middle East became part of the fight.
