Final answer:
The European allies entering the war influenced the American effort positively, providing military support, naval blockade, and cutting off British supplies. The Continental Army faced challenges at Valley Forge due to lack of manpower, organizational difficulties, discipline problems, and equipment shortages.
Step-by-step explanation:
The entrance of European allies into the war had a significant influence on the American effort. One key ally was France, which provided military support to the American forces. The French naval blockade prevented British reinforcements from reaching America and cut off British supplies. The French army also played a crucial role in the decisive American victory at the Battle of Yorktown. The support from European allies boosted the morale and resources of the Continental Army, enhancing their chances of winning the war.
However, the Continental Army still faced numerous challenges during the winter at Valley Forge. The soldiers suffered from lack of manpower, organizational difficulties, discipline problems, and equipment shortages. Many soldiers lacked bayonets and muskets, and the uniforms varied across units. The harsh winter conditions added to their hardships. Despite these challenges, the Continental Army managed to survive and eventually transform into a more professional fighting force under the guidance of figures like Baron von Steuben.
The European allies' entrance to both the American Revolutionary War and World War I crucially benefited the American military efforts through relief, recognition, and reinvigoration of the allied troops, despite the considerable logistical challenges faced at Valley Forge and the initial shock of modern warfare.
The entrance of European allies, specifically France after the Battle of Saratoga, had a significant impact on the American Revolutionary War. This alliance provided much-needed relief to the American troops and brought an international dimension to what had primarily been a colonial struggle. France's support was vital as it came with military assistance and recognition of American independence, which, in less than ten years would precipitate into the French Revolution, fundamentally altering the European landscape. Additionally, the American effort during the war faced tremendous challenges, as exemplified by the plight of the Continental Army at Valley Forge. Facing a lack of manpower, disorganization, discipline issues, and shortages of equipment and proper uniforms, the fledgling army struggled terribly. Yet, under the severe conditions of an unforgiving winter and training from European officers like Baron von Steuben, they emerged as a more disciplined and effective fighting force.
Meanwhile, in World War I, the American Expeditionary Force (AEF) provided a fresh and fervent boost to the weary Allied forces on the Western Front. Under General John J. Pershing, this injection of new American soldiers—dubbed doughboys—helped counter the effects of German submarines with the addition of naval escorts and shifted the balance on the Western Front as America's industrial might was also geared towards the war effort.
