The swampy ground along the banks of the various streams which crossed the line was generally impassable, so that it was sufficient to organise the spurs for defence, and to wire the gaps in the line where the streams flowed through. For the first half of January, however, the hard frost made it possible to move across these marshes, and constant patrolling was necessary to ensure the safety of the line.
Almost the only events which involved any fighting occurred on the night of the 9th/10th of January. In order to assist some operations of the 37th Division, the 20th carried out a demonstration in which artillery, Stokes mortars, machine guns, Lewis guns and rifle grenades all played a part. The 37th Division raided the enemy’s trenches twice during the night, and on both occasions the enemy put down a heavy barrage for an hour on the front and support lines of the 20th Division.
At 4.45 A.M. on 10th of January a party of the enemy, estimated at 30 to 50 strong, attempted to raid the left company of the 6th K.S.L.I. in the left sub-sector. The forward posts were temporarily driven in, but the positions were quickly retaken, and though the Germans failed to capture any of the K.S.L.I., they left two of their own party prisoners in our hands. About this time the 37th Division on the right was relieved by the 4th Australian Division.
On the 22nd of January the artillery of the 37th Division was relieved by that of the 20th, which from that date formed the Northern Group, under Major H. Price Williams, M.C. The battery positions extended between Zillebeke and Hooge. It was laid down that the policy of the artillery in this sector should be defensive and not aggressive, as it was not desired to stir the enemy into activity without good cause. Accordingly, while no favourable opportunity of inflicting loss on the enemy was missed, no harassing fire or fire without a definite object was carried out.
Throughout this period our patrols were active, as it was considered important that we should keep command of “No Man’s Land.” This was successfully done. A number of patrols went out from each brigade every night, and although they kept the enemy’s trenches and posts constantly under observation, as a rule no parties of the enemy were met. One patrol of the 7th D.C.L.I. had an unpleasant experience and was forced to spend a considerably longer time in front of the line than was expected. A liaison patrol of one N.C.O. and one man of this battalion had been sent out on the night of the 24th/25th to the battalion on the left. The patrol had encountered an enemy machine gun and the N.C.O. had been killed. An officer and one man of the D.C.L.I. went out at 4 A.M. on the 25th to investigate. They also found the machine gun, which opened fire on them at fifteen yards’ range. Fortunately they escaped, and they crawled away eastwards. At daybreak they found themselves between the enemy’s posts, and there they had to remain concealed in a shell-hole all day. As soon as it became dark they moved towards their own trenches, coming across a post of the enemy on the way, and then being driven back by Lewis gun fire from our line. Having thus had to spend another night out, they eventually rejoined their battalion at daybreak on the 26th.
Good work was done also by the machine gun companies. Between the 23rd and the 29th the 59th Machine Gun Company fired 36,000 rounds in indirect fire, and in conjunction with trench mortars silenced all the enemy’s forward machine guns near the Menin road, making the reliefs much easier to carry out.
On the 31st the Division was transferred from the IXth to the XXIInd Corps, under Lieut.-General Sir A. Godley, but as the XXIInd Corps took over the Menin road sector, this involved no change in the dispositions. On the night of the 7th/8th February the Divisional line was extended to the left as far as a point 600 yards east of the south-east corner of Polygon Wood. A readjustment of the inter-brigade boundary then became necessary, so that after this time each brigade had two battalions in the front line.
Meanwhile, the organisation of the Division had been changed. It had been decided to reduce all infantry brigades to three battalions each. On the 3rd of February three battalions—the 6th Oxford and Bucks L.I. (Lieut.-Colonel Boyle), the 10th K.R.R.C. (Lieut.-Colonel Sheepshanks), and the 10th R.B. (Lieut.-Colonel Morgan-Owen)—were told that they were to be broken up at once. The 7th K.O.Y.L.I. (Lieut.-Colonel Janson) were to leave the Division. The preparation of rolls and the many details which had to be settled in a short time involved a great deal of work, but it was quickly carried out. A certain number of the 10th K.R.R.C. and the 10th R.B. joined the 11th K.R.R.C. and the 11th R.B. and so remained in the Division, and in all units officers were given, as far as possible, their choice of various battalions to which they might go. In general, complete companies were posted to other battalions of their own regiments.
The order came as a great shock to battalions all of which had a fine record and in which esprit de corps stood high, and both officers and men felt the disbandment keenly.
By the 8th of February only a few headquarter details were left. Lieut.-Colonel Morgan Owen, commanding the 10th R.B., returned on the 12th from a conference to find that his battalion no longer existed. About the middle of the month the last few details went to the Divisional Wing of the Corps Reinforcement Camp.
