On the 4th June I accompanied Johnson, the battalion engineer, and Cozens, the adjutant, on an expedition to the north. We drove through Lillers and Bailleul to Ouderdom. I had not seen Bailleul since March 1915, when the 5th Divisional Cyclist Company, in which I had just received a commission, moved north to Ouderdom. Bailleul had not changed. It was still a clean and pleasant town, where you could buy fish. Tina, an almost legendary damsel, whose wit and beauty were known in five armies, had arisen and was about to disappear. The "Allies Tea Room" had opened. The lunatic asylum still held good baths that were open to officers twice a week. The "Faucon" was as dingy as ever.

In June the back area of the salient was like a disturbed ant-heap. We were making every possible preparation for an attack, and apparently we did not mind in the very least whether or not the enemy knew all about it. The countryside was "stiff" with light railways, enormous dumps, fresh sidings, innumerable gun-pits, new roads, enlarged camps. No advertisement of the impending attack was neglected. The enemy, of course, realised what was happening, and acted accordingly. He had brought up a large number of long-range guns, and his aeroplanes flew over on every fine day. He had, too, the advantage of direct observation over all the forward area. The results were unpleasant enough, even in June. Dumps would "go up" with a pleasing regularity. Camps and railheads were always being shelled. Bombing continued by day and by night. In front we destroyed the German trenches, breastworks and fortifications, and shelled their batteries. They retaliated in kind, and the unprejudiced observer would have found it difficult to award the prize. The enemy were scoring heavily with their gas shells.

We drove first to Ouderdom, a vast and enticing railhead, which the enemy shelled methodically each night, much to the annoyance of "B" Tank Battalion, who lived, for reasons of state, at the edge of the railhead. Their tanks were housed with disarming frankness in a series of canvas stalls surrounded by a high canvas screen. The whole erection was perhaps three-quarters of a mile in circumference. The tanks were so obviously concealed that the enemy never suspected their existence. The shells that dropped each night into the camp were the ordinary courtesies of warfare, although they did at last produce a move.

We had an excellent lunch with the Engineers of the battalion, Johnson expatiated on his new "unditching beam," we inspected certain novelties that had been fitted to the tanks, and then from a windmill on a hillock we watched the smoke of a "practice barrage." We drove on by Dranoutre, where in '14 I was despatch-rider to a brigade of the 5th Division, over the hill to the headquarters of "A" battalion in some pleasant woods, untroubled by the enemy. After drinks, salutations, and some "shop," we returned in the cool of the evening, stopping in the square at Hazebrouck for dinner and a good bottle of burgundy. It had been a fine day, with just enough sun. All the woods were fresh and green, and there was a purple sunset.

The Battle of Messines was fought four days later. The attack was a complete and overwhelming success. The whole of the Ridge, which for so many weary months had dominated our lines, was captured at a low cost. "A" and "B" battalions of tanks were useful but not indispensable. The ground was difficult and in places impossible. Many tanks became ditched. Certain tanks retrieved a local situation finely by the stout repulse of a strong counter-attack. We received the impression that, if the weather had been wet, tanks could not have been used. Although we did not realise it at the time, the battle of Messines was the first and only successful act in a tragedy of which the last act was never played.

An expedition to the Salient only sharpened our appreciation of the quiet and charm of Humières. What more could man want in the year of grace 1917 than to lie under the trees, sipping a cool drink, and watch Wright, the left-handed mainstay of our side, open his shoulders to a half-volley, or, when the sun had gone in, to stroll out and scrape together a lucky "6" instead of the usual "4"? We had no "seasons" at Humières. Each evening during the week we would play cricket, and on Sunday we would play a company of "F" battalion at football, and beat them by some outrageous score​—​12-love, I think it was​—​or, while we were indulging in the equivalent of a little net practice, the football enthusiasts would be crowded round the goal at the other end of the field. Whichever game we played, the company won most of its matches.

No self-respecting battalion would ever allow its period of rest to go by without battalion sports, and "D" battalion respected itself mightily. Our pet athletes started to train as soon as we reached Humières. After the Messines battle there was some doubt whether it might not be necessary to postpone the sports until after the next "show." Rumours of an immediate move came thick and fast, but the Fates were not so unkind, and our sports were held on the eve of things.

My company had prepared the way with a minor affair. The field was small and uneven, and in the longer races there were so many laps that, as our company wag exclaimed, it was a wonder the runners did not get giddy before they finished. If the times were doubtful, the enjoyment was unstinted, and after mess all the seats and the company piano were brought out into the open, and we sang songs until it was quite dark.

The battalion sports, a few days later, were a social event. An immense field positively sprouted with dark-blue flags, the colour of the battalion. There were pipes and drums from the 51st Division. The staff were conspicuously resplendent, while the Countess and her daughters were the centre of attraction. It was a splendid afternoon, although Battalion Headquarters won the cup. They would not have tried to win it, some one said, if they had not been able to drink out of it.

In the evening there was the usual entertainment of the "Follies" type under the direction of the "Old Bird." It was organised more or less on the spur of the moment. Supported by an issue of free beer it was an uproarious success, although it was sometimes not too easy to translate the jokes into French for the benefit of the Countess and her daughters.
