I saw a ghost at Béthune. He was a man called Private Challoner who had been at Lancaster with me and again in F company at Wrexham. When he went out with a draft to join the First Battalion he shook my hand and said: ‘I’ll meet you again in France, sir.’ He had been killed at Festubert in May and in June he passed by our C Company billet where we were just having a special dinner to celebrate our safe return from Cuinchy. There was fish, new potatoes, green peas, asparagus, mutton chops, strawberries and cream, and three bottles of Pommard. Challoner looked in at the window, saluted and passed on. There was no mistaking him or the cap-badge he was wearing. There was no Royal Welch battalion billeted within miles of Béthune at the time. I jumped up and looked out of the window, but saw nothing except a fag-end smoking on the pavement. Ghosts were numerous in France at the time. There was constant mining going on in this Cambrin-Cuinchy sector. We had the prospect of being blown up at any moment. An officer of the R.E. tunnelling company was awarded the Victoria Cross while we were here. A duel of mining and counter-mining was going on. The Germans began to undermine his original boring, so he rapidly tunnelled underneath them. It was touch and go who would get the mine ready first. He won. But when he detonated it from the trench by an electric lead, nothing happened. He ran down again into the mine, retamped the charge, and was just back in time to set it off before the Germans. I had been into the upper boring on the previous day. It was about twenty feet under the German lines. At the end of the gallery I found a Welsh miner, one of our own men who had transferred to the Royal Engineers, on listening duty. He cautioned me to silence. I could distinctly hear the Germans working somewhere underneath. He whispered: ‘So long as they work, I don’t mind; it’s when they stop.’ He did his two-hour spell by candle-light. It was very stuffy. He was reading a book. The mining officer had told me that they were allowed to read; it didn’t interfere with their listening. It was a paper-backed novelette called _From Mill Girl to Duchess_. The men of the tunnelling companies were notorious thieves, by the way. They would snatch things up from the trench and scurry off with them into their borings; just like mice.
