For the next two or three weeks we studied maps and aeroplane photographs, marking out our routes, starting-points, rear ammunition-dumps, forward dumps, and lines of supply. At last, then, our goal loomed up and these months of training, for the most part interesting, but at times terribly boring, would bear fruit. Two direct results were noticeable now on looking back to the time when we joined. First, each man in the Battalion knew how to run a tank, how to effect slight repairs, how to work the guns, and how to obtain the best results from the machine. Second, and very important, was the fact that the men and officers had got together. The crews and officers of each section knew and trusted each other. The strangeness of feeling that was apparent in the first days had now entirely disappeared, and that cohesion of units which is so essential in warfare had been accomplished. Each of us knew the other's faults and the mistakes he was prone to make. More important still, we knew our own faults and weaknesses and had the courage to carry on and overcome them. A few nights before we moved up the line, we gave a grand concert. Borwick and the Old Bird planned it. On an occasion of this sort, the Old Bird never grumbled at the amount of work he was obliged to do. Some weeks before we had bought a piano from one of the inhabitants of the village, and the piano was naturally the _piece de resistance_ of the concert. The Old Bird went around for days at a time, humming scraps of music with unintelligible words which it afterwards developed at the concert were awfully good songs of his own composing. The Battalion tailor was called in to make up rough Pierrot costumes. The Old Bird drilled us until we begged for mercy, while Borwick strummed untiringly at the piano. At last the great night arrived. A stage had been built at one end of a hangar, and curtains hung up. The whole of the Staff and H.Q. had been invited, and the _maire_, the _cure_, the _medecin_ of the village, and their families were also to attend. Promptly at eight o'clock, the concert began, with Borwick at the piano. Everything went off without a hitch. Although "K" Company provided most of the talent, the Battalion shared the honours of the entertainment. Each song had a chorus, and so appreciative was our audience that the choruses were repeated again and again. The one "lady" of the Troupe looked charming, and "she" arranged for "her" voice to be entirely in keeping with "her" dress and paint. The French spectators enjoyed it hugely. They were a great encouragement, for they laughed at everything uproariously, though it could not have been due to their understanding of the jokes. At ten o'clock we finished off with "God Save the King," and went back to our billets feeling that our stay in the village had been splendidly rounded off. IV MOVING UP THE LINE
