(D) ** Schlieffen Plan
EXPLANATIONS BELOW
Concept note-1: -In 1905 and 1906, Schlieffen devised an army deployment plan for a decisive (war-winning) offensive against the French Third Republic. German forces were to invade France through the Netherlands and Belgium rather than across the common border.
Concept note-2: -Prior to World War I, The Schlieffen Plan established that, in case of the outbreak of war, Germany would attack France first and then Russia. Instead of a ‘head-on’ engagement, which would lead to position warfare of inestimable length, the opponent should be enveloped and its armies attacked on the flanks and rear.
Concept note-3: -The Schlieffen Plan was a battle plan drawn up by German military strategists. Its purpose was to secure victory in a war against both France and Russia. It formed the basis of Germany’s offensive in August 1914 but its successes were limited.
