Second Battle of Artois
The Battle of Festubert (15–25 May 1915) was an attack by the British army in the Artois region of France on the western front during World War I. The offensive formed part of a series of attacks by the French Tenth Army and the British First Army in the Second Battle of Artois . After the failure of the breakthrough attempt by the First Army in the attack at Aubers Ridge (9 May 1915) tactics of a short hurricane bombardment and an infantry advance with unlimited objectives, were replaced by the French practice of slow and deliberate artillery-fire intended to prepare the way for an infantry attack.
