After about a month’s work, Montagu Parker and Robin Duff returned to England for a few weeks. Of the English contingent Clarence Wilson, Cyril Foley and the Pearsons engineer Mr Walsh, remained in Jerusalem. On the 30th August, Foley and Walsh explored the Dragon’s Shaft, which connects to Warren’s Shaft. They believed this might well be the perpendicular passage to which the cyphers referred so frequently. As it was some distance into the tunnel, they could only bring short ladders to the bottom of the shaft. There they lashed seven six-feet ladders together. They did this by candlelight, standing in water. Then they tossed a coin to see who would have the dubious privilege of ascending first and the engineer Walsh lost, so he climbed the ladders. Foley watched Walsh disappear into the dark and stepped back so that anything or anyone falling would not hit him. Twenty minutes later, Walsh descended and informed Foley:
“I’ve had rather an exciting time. There’s a slope of rock at the top of the shaft, and I got onto it, but it was so slippery I slid back, and if I had not luckily struck the top of the ladder you would have seen me sooner.”
Foley decided to look for himself and he climbed up. At the top, the ladder was not resting on anything as the shaft sloped away at a forty-five degree angle. He could see a large domed roof above him. To his right was a steep passageway filled with boulders approached by a slope ‘as slippery as ice’. He was contemplating that only he, Walsh, Charles Warren and Sergeant Birtles had seen this spot in 1,800 years when:
“I heard a movement away up the passage and, to my intense horror, something came rushing down it with a speed of thought. Before I could move a dreadful shape hit me full on the shoulder knocking the candle out of my hand and leaving me in opaque darkness. Being deprived of all volition through sheer terror, I mechanically beat all records down the ladder”
Once he had composed himself, he realised a bat had flown into him, drawn by the light from his candle. After seven hours in the tunnel, Foley and Walsh decided they had earned dinner.
