In this sector the 1/4th Londons found their own supports which were billeted in cellars in South Maroc, a mining village built on the unattractive "square" plan of American cities, and consisting of innumerable rows of artisans' dwellings, then unhappily in a state of complete ruin. The cellars of these dwellings, however, still afforded sufficient cover for the concentration unobserved by the Germans of a considerable body of troops, and the Germans were evidently somewhat disturbed at the prospect of this for their artillery, both light and heavy, paid continual attention to the village both day and night.
This sector having once more come into occupation by British troops an enormous amount of work was immediately necessary to complete the front line and company supplies of small arms ammunition, bombs, rifle grenades and trench stores of all sorts; and this support and reserve companies were kept busily engaged in this work throughout the tour of duty.
In this sector also the steel shrapnel helmet first made its appearance, so far as the 1/4th Londons were concerned. It is amusing to look back on the distrust with which its advent was first regarded by all ranks alike—although afterwards, when once its efficiency and protective qualities had been tested, it was as highly prized as it had been previously shunned. The first issue was made at the rate of one helmet per fire bay, the honour of wearing it falling to the man on sentry duty for the time being, and most remarkably disinclined the men were to assume this undesired badge of office.
On the 9th the 140th Brigade was relieved in the line by the 142nd, moving on the 13th into the Loos sector, where it took over the trenches of the 141st Brigade. The 1/4th Londons did not take part in this relief but remained in the right subsection, temporarily under the orders of the 142nd Brigade, with the 22nd Londons on their left. Here the Battalion remained until the 16th, when it was relieved by the 17th Battalion, rejoining the 140th Brigade in rest billets at Haillicourt.
On the 19th January Lieut.-Col. L. T. Burnett left the Battalion on short leave, and as it unfortunately proved, permanently, for he fell seriously ill while on leave and was unable to return to duty for nearly a year. The command was assumed during his absence by Major W. G. Clark, D.S.O., while Major S. Elliott became temporarily second in command. The loss of Lieut.-Col. Burnett was keenly felt. His nine months' command had been marked by a striking advance in the Battalion's efficiency and by the unswerving loyalty of all ranks under his command. Later he joined the Reserve Battalion in England, being subsequently transferred to employment in the War Office.
At Haillicourt the Battalion spent a few days in rest and training and returned to the trenches on the 24th January, occupying the same subsector as on the previous occasion with the 7th Londons once more on its left.
This tour of duty was marked by particularly heavy artillery activity on both sides, the Germans shelling our trenches and Maroc daily with great accuracy and using a good deal of gas shell. A certain number of casualties inevitably occurred, but, having regard to the continued intensity of the bombardment, the number was remarkably small.
On the 27th January the Kaiser's birthday was celebrated, and it was somewhat confidently anticipated that, as in 1915, the Germans would endeavour to score some success against the British. It had been known for some time that enemy mining operations in this area had been proceeding apace, and it therefore appeared not improbable that the Germans would endeavour to time the firing of their mines for the 27th. Preparations to meet this possibility were made. The Kaiser's birthday did indeed prove to be a day of considerable activity, and though the Germans delivered an abortive attack against the 15th Division on the left no infantry movement occurred opposite the 140th Brigade; and their activity was confined to shell fire, which assumed serious proportions on the 27th and again on the 28th. Our artillery, however, was ready with heavy retaliatory fire and by the evening of the 30th conditions in the Maroc sector had reverted to something approaching quietness.
During this period the newly arrived 16th (Irish) Division of the New Army was attached to the 47th Division for instruction in trench warfare, the 1/4th Londons taking over the supervision of the 8th Munsters, among whom unfortunately several casualties were caused by hostile shell fire on the 30th. The 31st January was marked principally by heavy British artillery fire, which elicited but little response from the enemy and inflicted considerable damage on his wire and defences generally.
The following day the 140th Brigade handed over its trenches to the 142nd, the 1/4th Londons being relieved by the 21st Londons and proceeding to rest billets in Haillicourt.
