The Second Battle of the Aisne (Bataille du Chemin des Dames or Seconde bataille de l'Aisne, 16 April – mid-May 1917) was the main part of the Nivelle Offensive, a Franco-British attempt to inflict a decisive defeat on the German armies in France. The Entente strategy was to conduct offensives from north to south, beginning with an attack by the British Expeditionary Force (BEF) then the main attack by two French army groups on the Aisne. General Robert Nivelle planned the offensive in December 1916, after he replaced Joseph Joffre as Commander-in-Chief of the French Army. The objective of the attack on the Aisne was to capture the prominent 80 km (50 mi), east–west ridge of the Chemin des Dames, 110 km (68 mi) north-east of Paris and then advance northwards to capture the city of Laon. When the French armies met the British advancing from the Arras front, the Germans would be pursued towards Belgium and the German frontier. The offensive began on 9 April, when the British began the Battle of Arras.
