On August 29, 1916, General Paul von Hindenburg replaced Von Falkenhayn as German chief of staff. An excerpt from the article:
"He served as Chief of the Imperial German General Staff for part of the First World War before his eventual dismissal by Kaiser Wilhelm II. Having joined the army at an early age Falkenhayn served as a military instructor to the Chinese army in 1899, where he remained until 1903. During the Chinese Boxer Rebellion he was a member of the German General staff, seeing action when the Allies marched to relieve besieged Peking.
Upon his return to Germany, Falkenhayn continued to serve on the German General staff, and was appointed Prussian Minister of War in 1913. Whilst in this role he and Helmuth von Moltke, then Chief of Staff, frequently clashed. However, with the declaration of war in August 1914 and the German setback at the Marne, the Kaiser, Wilhelm II, dismissed Moltke and replaced him with Falkenhayn on 14 September 1914.
Falkenhayn's cautious nature appeared to make him well-suited to the realities of trench warfare, unlike many of his contemporaries. He was inclined to consider defensive rather than offensive operations - a sound strategy but one ill-suited to the Eastern Front. His approach led him to reject an ambitious plan to capture the entire Russian army championed by Paul von Hindenburg and Erich Ludendorff.
Falkenhayn however believed that the real war was being fought on the other front, the Western Front. He conceived the idea of besieging the historic French city of Verdun in early 1916, of "bleeding it white" as he phrased it. He planned to draw the bulk of the French army into the Verdun salient, thus effectively tying up the French army, and then to methodically destroy them with concentrated artillery fire.
Certainly French losses at Verdun were significant, as were German casualties. It succeeded in diverting French attention solely towards the defence of Verdun, to the extent that the British offensive on the Somme on 1 July 1916 was executed as much as anything else to provide relief for the French forces at Verdun. Even so, the German Verdun offensive was ultimately a failure; indeed, by the time the Somme offensive was started the French were already beginning to claw back ground.
With the failure of the Verdun offensive, for which the German Chancellor, Theobald von Bethmann-Hollweg, was scathing, together with the Russian resurgence at the hands of Brusilov, the loss of Bitolj to the Serbs, and the fall of Gorizia to Italy, the Kaiser finally decided to replace Falkenhayn with the more aggressive von Hindenburg on 29 August 1916 when he heard news of Roumania's declaration of war with Austria-Hungary."
