After scraping off the remains of the mud it had carried from the trenches, the Battalion settled down at Hedauville to a normal programme for ten days. The weather was bad, and a good deal of sickness now occurred among the troops, until so many officers were sick that leave for the others was stopped. Of general interest little occurred to mark this first fortnight of December. At its close the Battalion marched back to Martinsart and reoccupied its former huts. Battalion and Brigade were now in support, and our energies were daily devoted to working parties in the forward area. As these were some of the most arduous ever experienced by the Battalion I will describe an example. I take December 16--a Saturday. My company was warned for working party last night, so at 6 a.m. we get up, dress, and, after a hurried breakfast, parade in semi-darkness. As the outing is not a popular one and reduction in numbers is resented by the R.E., the roll is called by Sergeant-Major Brooks (recently back from leave and in the best of early morning tempers) amid much coughing and scuffling about in the ranks. At 7 a.m. we start our journey towards the scene of labour, some 80 strong (passing for 100). We go first along a broad-gauge railway line (forbidden to be used for foot traffic) and afterwards through Aveluy and past Crucifix Corner to near Mouquet Farm. After a trivial delay of perhaps 40 minutes, the D.C.L.I. or 479 have observed our arrival and tools are counted out and issued, the homely pick and shovel. The task is pleasantly situated about 150 yards in front of several batteries of our field guns (which open fire directly we are in position) and consists in relaxing duckboards, excavating the submerged sleepers of a light railway or digging the trench for a buried cable. Perhaps the work only requires 50, not 100 (nor even 80) men. Very well! It is a pity those others came, but here are a thousand sandbags to fill, and there a pile of logs dumped in the wrong place last night, so let them get on with it! For six hours we remain steadily winning the war in this manner and mildly wondering at the sense of things and whether the Germans will shell the batteries just behind our work--until, without hooter or whistle, the time to break off has arrived. By 3 p.m. the party is threading its way back, and as darkness falls once more reaches the camp. Cries of 'Dinner up' and 'Tea up' resound through the huts, and all is eating and shouting.
