Soon after this episode there came upon the scene what were commonly known as “Cook’s Tourists.” These were officers whose units were still at home, and who were sent out to gain experience by being attached to batteries for a short period. At times the tourist laid himself open to being the victim of many practical jokes, and this certainly contributed to the liveliness of the mess. A certain officer was escorted down to the front line trenches one day, and, as usual, the party was armed with periscopes. All of a sudden he emitted a cry of delight, as, gazing through the instrument, he told us of how crowds of the enemy were walking along a road. Could we not get our guns on to them quickly? This seemed an incredible occurrence, as, in this sector, not a single German had been seen for days on end. The mystery was speedily solved, however. By some means or other, he had been holding the periscope so that it faced the opposite direction, and what he actually saw was a party of our own men walking leisurely along the road some way behind our lines. Needless to say, this officer came in for a considerable amount of chaff, and, in course of time, was solemnly presented with a paper medal, suitably inscribed, on which reversed periscopes figured prominently. The festive season was now drawing near, which necessitated the gathering of provisions, for the men were to celebrate the 25th of December by having a special dinner, and presently leave was opened to our unit and the first lucky ones departed for “Blighty.” Some sort of gift was due the enemy on this occasion, and it took the shape of a sharp five minutes’ bombardment, from every gun in the area, on the stroke of midnight on Xmas Eve. In spite of this gruelling, the enemy next morning showed signs of wishing to fraternise with our men in the front line, but strict orders had been issued in advance that this was not to be countenanced. The Germans showed themselves freely above the parapet, and one could see that they had been dressed up smartly for the occasion, probably in order to impress us with their appearance. However, there was “nothing doing.” Little or no sniping took place, but the artillery went through their usual routine, in fact rather increased their fire that day. The men’s dinner was a great success, and all seemed pleased with their fare—pork and potatoes, vegetables, plum pudding and fruit, with plenty of beer or stout to wash it down. The Officers’ Mess was lively also, and our first ’Xmas, under war conditions, was voted most successful. Next day the Padre turned up, and a service was held in one of the barns, but, in the middle of the address, on “Peace on earth, goodwill towards men,” there was a sudden call for “action.” A rush was made to the guns, and, after a few minutes’ argument with the enemy, we returned and finished listening to the discourse. Somehow or other one could not help feeling that the two happenings were incongruous!
