Final answer:
After the Saint-Mihiel offensive, the Allies continued their momentum with the Meuse-Argonne offensive, contributing to the end of World War I with the Armistice of November 11, 1918. Subsequently, there were extensive treaty negotiations and a period of recovery and rebuilding in war-torn Europe, which led to the reformation of borders and sociopolitical landscapes.
Step-by-step explanation:
After the Saint-Mihiel offensive, which saw the Allies, with significant American assistance, successfully push back the Germans in September 1918, the Allied forces continued their advances against the German armies. The next significant action was the Meuse-Argonne offensive.
This campaign was part of the final Allied push that would ultimately lead to the end of World War I with the signing of the Armistice on November 11, 1918. Following the armistice, treaty negotiations commenced, notably resulting in the Treaty of Versailles.
The Great War left Europe and the participating countries in devastation, both physically and emotionally. French society, after the war, faced the difficult task of recovery and rebuilding, amid political changes and social upheaval.
The landscape of post-war Europe involved the creation of new nations, the redrawing of borders, and the setting of the stage for future conflicts, expressed by the rise of new ideologies and the eventual start of World War II, where France was conquered and divided by Nazi Germany leading to the establishment of the Vichy government.
Moreover, the personnel involved in the war—such as fruit pickers, factory workers, nurses, and ambulance drivers—had to adjust to a post-war society and find new roles or revert to their pre-war lives.
