A detailed, illustrated account of The First Battle of the Marne, which saved France from defeat in the First World War and led directly the establishment of the trenches.

In 1914 the Germans launched an offensive that swept through Belgium and into France, threatening to crush French resistance in one fell swoop. However, through careful maneuvering and stubborn resistance, the French Army, aided by the BEF, blunted the assault, winning an important strategic victory that kept France in the war. This victory ensured that Germany would have to fight a two-front war, and the Western Front descended into the stalemate of trench warfare.

One of the most important battles in the First World War, the First Battle of the Marne would be the last battle of maneuver to be seen on the Western Front for several years to come.
