On the night of the 31st March the Brigade returned to the trenches, relieving the Sirhind Brigade in a sector north of Neuve Chapelle village, the right boundary of which was Sign Post Lane, a road running through the lines in the direction of the Bois du Biez.
The 4th London was again in Brigade Reserve, and moved from Paradis at 7 a.m. to Les Huit Maisons, where it remained in temporary billets until dusk when it advanced to Croix Barbée, Battalion Headquarters occupying a house at the corner of Loretto and Edward Roads. This house will be in the recollection of those who served in this area in 1917 as the site of St Vaast R.E. dump. Here the Battalion was again under instruction in trench duties with the Connaughts, who were in the right subsection of the new Brigade sector, but on this occasion companies went into the line in turn as a whole, the companies not actually in trenches occupying reserve posts at Loretto, Green Barn, and St Vaast.
The right subsection was defended by breastworks and was immediately facing Pietre, the hamlet which had stood between our troops and success on the afternoon of the 10th March. It included the peculiar feature of the Duck's Bill, in regard to which a word of description may not be out of place. The name Duck's Bill brings to the minds of most 4th London men the picture of a large defended mine crater quite close to the German line, and approached by a defended sap which was generally full of water. Such it was in the winter of 1916/17, but in the spring of 1915 the Duck's Bill was a ruined farmhouse standing on a knoll just in front of the cross-road connecting Sign Post Lane with Sunken Road. This ruin was surrounded by a horseshoe trench, the points of the horseshoe resting on the cross-road, which was barricaded and connected with the front line by a rough breastwork. The defences here were still in an unfinished condition as the farmhouse was the extreme point of our advance in this sector in the battle, and the road barricades were under the continual watch of German snipers in Pietre. On the night of our entry into this sector the farmhouse had just been demolished by German incendiary shells and the ruins were still smouldering.
"A Bosche had been buried," writes Captain Moore, "in the hastily constructed parapet, face downward, and with his booted feet sticking into our trench. They were Bosche boots, so presumably were on Bosche feet, and every time one passed in the dark one knocked them—a truly gruesome spot."
The Duck's Bill farmhouse was finally disposed of when the mine crater was blown in 1916.
The reserve posts to which the companies in reserve were detailed were defended keeps forming with others the Croix Barbée line of defence. The aftermath of the battle, which had taken the form of such vigorous shelling by the enemy, now exhausted itself and this tour proved particularly quiet. The enemy's attention was paid principally to the roads and communications in rear of our trenches, but his shelling was sporadic and harmless.
On the 11th April the Battalion moved out of Croix Barbée, marching at 5 p.m. for Paradis, where it was joined the following day by the remaining units of the Brigade, now in Divisional reserve.
Of the rest in Paradis little need be said. The twelve days were spent in training under company arrangements and in bathing, completing issues of deficiencies in clothing, etc. On the 16th and 17th April, however, practice attacks on trenches were carried out as a brigade exercise, and although no definite information was, at the time, conveyed to the units as regards the purpose of the practice, the exercise was in preparation for the rôle which the Brigade would be called upon to play during its next tour in the line. It was, therefore, with the greater satisfaction that the 4th Londons carried out the exercises in leading the assaulting columns beside the Connaught Rangers.
The novitiate of the Battalion was now over, and it was accepted as being in every way able to do its full duty as a unit of the Ferozepore Brigade, and the knowledge that it had "found itself" was in itself the best possible incentive to all ranks to uphold worthily the honour of their regiment. The weather was of the most perfect spring type, and the ground and dykes were once more in their normal condition for the time of year. Speculation was rife, therefore, as to the task which was destined to be set the Brigade on its return to the line.
