How does evidence shape Schlieffen Plan?

Narrative sequence: answer How does evidence shape Schlieffen Plan by focusing on Part two: The First World War: stalemate. Use the chronology of BA Conflict and tension: the First World War, 1894-1918, select named evidence connected to Study the Schlieffen Plan, including reasons for the plan, its failure, the Battle of the Marne and its contribution to stalemate, and order events accurately, show movement from one development to the next, and avoid jumping chronology.

This exam-style task requires a developed historical argument rather than a list of facts. Begin with the relevant period from Paper 1 Section B: Wider world depth studies, then anchor the answer in Part two: The First World War: stalemate. The evidence should connect to Study the Schlieffen Plan, including reasons for the plan, its failure, the Battle of the Marne and its contribution to stalemate and be explained through cause, consequence, change, continuity, significance or interpretation as appropriate. A strong final judgement shows why the selected evidence is more convincing than a vague or unsupported claim.
