Answer:
The entry of the US in WWI sent the Germans back from the western front in France as the Germans plan at a swift attack failed and turned into a long out numbered trench battle.
Explanation:
The Schrieffer Plan’s strategy required that France be defeated swiftly with a right hook strategy into France and allowed the Germans to fight a 2 front battle on the western front with France and the Russian eastern front.– but this didn’t happen due to heavy armament of the US troops on the western front. That failure led to sustained trench warfare on the Western Front. In those grim battles of attrition, such as the Battle of the Somme and the Battle of Verdun, Allied forces ultimately outnumbered the Germans eventually sending them to retreat and surrender.
