why was there more movement on the eastern rather than on the western front of wwi
Eastern Front (World War I) While World War I on the Western Front developed into trench warfare, the battle lines on the Eastern Front were much more fluid and trenches never truly developed. This was because the greater length of the front ensured that the density of soldiers in the line was lower so the line was easier to break. Once broken, the sparse communication networks made it difficult for the defender to rush reinforcements to the rupture in the line, mounting rapid counteroffensives to seal off any breakthrough.
American Expeditionary Forces The American Expeditionary Forces (AEF) was the expeditionary force of the United States Army during World War I. It was established on July 5, 1917, in France under the command of General John J. Pershing. During the United States campaigns in World War I it fought alongside the French Army, British Army, Canadian Army and Australian Army on the Western Front, against the German Empire. A minority of the AEF troops also fought alongside the Italian Army in that same year, against the Austro-Hungarian Army. The AEF helped the French Army on the Western Front during the Aisne Offensive (at the Battle of Château-Thierry (1918) and Battle of Belleau Wood) in the summer of 1918, and the AEF fought its major actions in the Battle of Saint-Mihiel and the Meuse-Argonne Offensive in the latter part of 1918.
