Orders were therefore being issued that these mounds were to be levelled down so that a man could stand on the fire-step and have a clear field of fire all round him. The German attack, however, came before this order could be put into effect, with the result that the men in their deep trenches were suddenly assailed from their flanks and rear by an enemy whom they could not see to shoot before he was within bombing range of them. They thus had little opportunity of offering effective resistance to the enfilade attack, and were, no doubt, in consequence rapidly overwhelmed. The levelling down of the excavated earth during trench construction subsequently became a standing order in the Division. CHAPTER XV. THE GERMAN OFFENSIVE (_Contd._)--THE BATTLE OF THE LYS. On 1st April the Division moved by train to an area near Bethune, where it remained for a few days resting and refitting. The only event of interest that occurred in this area was the accidental bombing by daylight of the vicinity of Divisional headquarters by a British reconnaissance aeroplane, fortunately without casualties. On 7th April the Division was transferred to the XIth Corps, and was moved to an area in rear of the Portuguese Divisions, which at the time were holding the line about Neuve Chapelle and Festubert. Divisional headquarters was established at Robecq, a village which it had occupied on its first arrival in France. The 152nd Brigade were billeted at Ham en Artois, the 153rd Brigade at Busnes--or Business, as the Jocks called it,--the 154th Brigade at Gonnehem, and the Divisional artillery at Amettes. The units were in the throes of reorganisation under most difficult circumstances. Some three thousand men had joined as reinforcements, but few new officers had arrived; moreover, the authorities at the base had made confusion worse confounded by posting Gordons to Black Watch battalions, and Seaforths to Argylls, and thereby had considerably tried the temper of the men and increased the difficulties of their commanders. While the Division was resting in this area, there was much speculation as to whether the enemy's effort had not spent itself in the south, and whether he was likely to make a similar attempt in this part of the front, with a view to threatening the Channel ports. Ultimately the same white directing posts were reported on the enemy's front as had appeared opposite to the Division just prior to the German attack on 21st March, and it was then generally felt that a new offensive in this part of the front could be anticipated with certainty. At this time arrangements were being made for the relief of the two Portuguese Divisions in the line, with a view to the frontage held by them being taken over by the 50th and another Division. This relief was planned to take place on 10th April.
