World War I, also known in its time as the “Great War” or the “War to End all Wars”, was an unprecedented holocaust in terms of its sheer scale. Fought by men who hailed from all corners of the globe, it saw millions of soldiers do battle in brutal assaults of attrition which dragged on for months with little to no respite. Tens of millions of artillery shells and untold hundreds of millions of rifle and machine-gun bullets were fired in a conflict that demonstrated man’s capacity to kill each other on a heretofore unprecedented scale, and as always, such a war brought about technological innovation at a rate that made the boom of the Industrial Revolution seem stagnant.

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.

For much of 1917, things went the Germans’ way. With the Bolshevik Revolution underway, the Germans were able to move soldiers to the Western front as the Russians quit the war. Moreover, the Allied powers had failed badly in its Nivelle Offensive in May 1917 and suffered a defeat in November against at the Battle of Caporetto in Slovenia. Unbelievably, the French and British had not bothered to coordinate their commands until after those defeats, but they finally formed a Supreme War Council to coordinate their armies’ movements and strategies.

Despite those successes, when the United States joined the war in April 1917, it began mobilizing four million soldiers to join the war. The central powers knew that it would take months before the United States could land a substantial number of troops in Europe to join the fighting, and the Germans hoped to force the Allied powers to quit before the United States could make a difference.

Thus, the Germans’ spring offensive began in March 1918, using new infantry tactics to move on the most lightly defended points of the Allied trenches. The Germans quickly obtained a breakthrough and broke the Allied lines, pushing the Allied forces back nearly 40 miles, and the Germans were once again within less than 100 miles of Paris. Once again, however, the Allied powers halted the Germans’ drive, with the help of reinforcing American and Australian troops. The Germans were right back where they started by July 1918, at which time about 10,000 Americans were arriving in France each day.

Nestled between green forests and flowing rivers, the country around the French city of Soissons was an idyllic scene of small villages, golden wheat fields, cow pastures, and sloping ravines. It was, and still is, also the site of a convergence of the French railroad and highway system, making it a fiercely coveted area by both sides during World War I. In July 1918, its bucolic milieu stood interrupted here and there by the appearance of blackened ruins of tanks and burned out farm buildings. After five weeks of German possession, Allied commanders decided it was time to take this strategic area back.

After four years of brutal, savage, and devastating fighting, the battle fought there in July 1918 marked the beginning of the end of the war as the Allied forces begin to put the German invaders on the run.
