During February 1915, the division launched minor attacks and captured several German positions. Trench raids followed, until the 2nd Division took part in the Battle of Neuve Chapelle in March, and suffered over 600 casualties. Trench raids were sandwiched between the division's activities in the Battle of Festubertpart of the Second Battle of Artoisin May, and the Battle of Loos (September–October). The bloody fighting of the former saw minor advances made, heavy casualties inflicted on the Germans, and a further 5,446 divisional casualties. At Loos, the division deployed chemical weapons for the first time. However, due to light wind, the gas clouds hung along the division's line. The first day's attack had mixed results, and ranged from an attack that stalled as soon as the men left their trenches, to sections of the German first line of trenches being captured. Afterwards, minor attacks were launched and German counterattacks fended off. By the end of the battle, the division had lost 3,400 men with the majority inflicted on the first day.
