The enduring image of World War I is of men stuck in muddy trenches, and of vast armies deadlocked in a fight neither could win. It was a war of barbed wire, poison gas, and horrific losses as officers led their troops on mass charges across No Man’s Land and into a hail of bullets. While these impressions are all too true, they hide the fact that trench warfare was dynamic and constantly evolving throughout the war as all armies struggled to find a way to break through the opposing lines.
Needless to say, the First World War came at an unfortunate time for those who would fight in it. After an initial period of relatively rapid maneuver during which the German forces pushing through Belgium and the French and British forces attempting to stymie them made an endless series of abortive flanking movements that extended the lines to the sea, a stalemate naturally tended to develop. The infamous trench lines soon snaked across the French and Belgian countryside, creating an essentially futile static slaughterhouse whose sinister memory remains to this day.
If trench warfare was inevitable during the war, it is only because the events leading up to the First Battle of the Marne were quite different. The armies at the beginning of the war moved quickly through the land, but the First Battle of the Marne devolved into a bloody pitched battle that led to the construction of trenches after the Germans retreated, blocked in their pursuit of Paris. When the aftermath disintegrated into a war between trenches, some Germans thought they had the upper hand since they were occupying French territory, but with fewer soldiers than the combined Allied nations and fewer resources and supplies, it was possibly only a matter of time before they were ultimately defeated.
