Since the bitter struggle at Ypres in November 1914, the enemy had, in the opinion of Sir John French, shown certain signs of weakening on the Western Front, and this was attributed by him to the success which was attending the Russian offensive in East Prussia, and to the consequent withdrawal of German troops from the West. In order to assist our Russian Allies as far as possible it was necessary to have resort to active operations with the main object of holding as many of the German reserves as possible in the West, and efforts to this end were already being made by the French at Arras and in Champagne. The ravages caused during the winter trench warfare by sickness and "trench-foot," which had had especially disastrous effects on those regular divisions composed of troops withdrawn from tropical garrisons, rendered necessary the early cultivation of a vigorous offensive spirit, and these combined considerations led Sir John French to the decision to take the offensive as soon as the condition of the ground in Flanders should afford such an undertaking a reasonable prospect of success. By the beginning of March the conditions were considered sufficiently favourable, and the terrain selected for the proposed offensive was the German positions opposed to the First Army and defending the lower slopes of the Aubers Ridge. The objective of the First Army's attack was the advancement of our line to the high ground about Illies and Hermies as a prelude to the occupation of La Bassée, and this involved as a first local objective the capture of the village of Neuve Chapelle. The Aubers Ridge is a strongly marked hill feature, which runs in a south-westerly direction from Lille until it loses itself in the marshlands in the neighbourhood of La Bassée. Neuve Chapelle, which had already changed hands several times in the fighting of the previous autumn, is a small village, the immediate surroundings of which are much intersected with orchards and fences, about 1000 yards from the lowest slopes of the Ridge, which, immediately opposite to it, are covered by a considerable wood called the Bois du Biez. The German defensive position skirted in front (or to the north-west) of Neuve Chapelle and then making a sharp turn southwards, followed the line of the Estaires-La Bassée Road, for some 600 yards, from its junction with Foresters Lane (Rue des Berceaux) to its junction with the Rue du Bois, where once more turning slightly to the west it left the hamlet of Richebourg L'Avoué in the British lines, and finally made a wide sweep once more to the south in the direction of Festubert (see Map No. 1). The front of attack allotted to the Indian Corps was that part which followed the alignment of the La Bassée road between Rue du Bois and Foresters Lane, the actual capture of the greater part of Neuve Chapelle being entrusted to the 8th Division.
