- James Dixon Nicholson (17488) enlists at Alston, Cumberland.
- Battalion is incorporated into the 5th Army.
- Letter from Cumberland County Council Health Department: "enclosing....an account for £1. 6. 4. Incurred for needles used in inoculating your men....We have most gladly given our services and will always be willing to do whatever we can, and I think you will agree that the Army ought to bear this cost." 
- Copy letter from Lt-Col. Machell: "The Cumberland Infirmary at Carlisle, kindly agreed to accept a limited number of our more serious cases on payment of 1/9 per day, the amount allowed for our messing. This is by far the best arrangement that can be made. Our own ambulance takes our sick from our medical detention room in the camp, straight to the Infirmary."
- Letter from General Collings to Lt-Col. Machell: "to let you know how pleased I was with all you showed me today. When you see Lord Lonsdale will you tell him how greatly I was struck with the evidence of what he has done for the Battalion and of the interest he takes in its welfare. I shall write to Western Command informing them of my inspection and satisfaction and I shall also mention about the quality of the boots as there is a very general complaint and something should, if possible, be done in the matter." 
- Officer Struck Off: "the Officer Commanding wishes to place on record his appreciation of the services rendered by Colonel Haworth....in raising and training C Company which he brought to Headquarters....feels the Westmorland Company will never lose the impression of Colonel Haworth’s personality, and thanks him for contributing this splendid contingent to the ranks of the Lonsdale Battalion." 
- Order for 148 axes, 148 pick axes and 222 shovels.
- Relieves the 17th Highland Light Infantry in the F1 sector near Aveluy.[a] During this period one man is wounded.
- Lt-Col. P.W. Machell, for period 7–14 January:
"It is delightful how easily all the working parties can be arranged, and how satisfactorily an immense amount of work is done with a minimum amount of fatigue to the men, by careful and systematic arrangement beforehand. We do more than twice what the others do, and our men do it twice as easily. It is all very small, but it is good to see the result, both in the work and in the men themselves....I have three patrols every night. They go cautiously at first, and I get them to go a bit wider every night, so as gradually to get confidence.
One of our patrols bumped into a German one a few night ago. Germans retired and we got our machine-gun on to them; one German got left, and was brought in in triumph, everyone much pleased. Last night patrol, under Matthews, the police sergeant, got right inside the German wire and located a big working party in the open. Got back and put a M.G. and a lot rifles on to them—groans, lights flying about, silence for half an hour, and then retaliation with whizz-bangs and rifle grenades—no effect. Quite good. It has given them a start, so much turns on the way the first things go. We have located a spot where I believe they are making a trench mortar battery, so we have arranged for our artillery to flatten this place quite out to-morrow. The new R.A. is first class."
