Robert Georges Nivelle was a French artillery general officer who served in the Boxer Rebellion and the First World War. In May 1916, he succeeded Philippe Pétain as commander of the French Second Army in the Battle of Verdun, leading counter-offensives that rolled back the German forces in late 1916. During these actions, he and General Charles Mangin were accused of wasting French lives. He gave his name to the Nivelle Offensive.
