"That being the general idea, so to speak, I wandered off one day to see the bridge. As I expected, it was guarded, but by somewhat indifferent-looking Huns—evidently only lines of communication troops. For all that, I hadn't an idea how I was going to do it. Still, luck, always luck; the more you buffet her the better she treats you.

"One week after I got there I heard the battery was going out: and they were going out that night. As a matter of fact, that hadn't occurred to me before—the fact of them moving by night, but it suited me down to the ground. It appeared they were timed to leave at midnight, which meant they'd cross the bridge about a quarter or half past. And so at nine that evening I pushed gently off and wandered bridgewards.

"Then the fun began. I was challenged, and, having answered thickly, I pretended to be drunk. The sentry, poor devil, wasn't a bad fellow, and I had some cold sausage and beer. And very soon a gurgling noise pronounced the fact that he found my beer good.

"It was then I hit him on the base of his skull with a bit of gas-pipe. That sentry will never drink beer again." Brent frowned. "A nasty blow, a dirty blow, but a necessary blow." He shrugged his shoulders and then went on.

"I took off his top-coat and put it on. I put on his hat and took his rifle and rolled him down the embankment into a bush. Then I resumed his beat. Discipline was a bit lax on that bridge, I'm glad to say; unless you pulled your relief out of bed no one else was likely to do it for you. As you may guess, I did not do much pulling.

"I was using two slabs of gun-cotton to make sure—firing them electrically. I had two dry-cells and two coils of fine wire for the leads. The cells would fire a No. 13 Detonator through thirty yards of those leads—and that thirty yards just enabled me to stand clear of the bridge. It took me twenty minutes to fix it up, and then I had to wait.

"By gad, old boy, you've called me a cool bird; you should have seen me during that wait. I was trembling like a child with excitement: everything had gone so marvellously. And for the first time in the whole show it dawned on me that not only was there a chance of getting away afterwards, but that I actually wanted to. Before that moment I'd assumed on the certainty of being killed."

For a moment he looked curiously in front of him, and a slight smile lurked round the corners of his mouth. Then suddenly, and apropos of nothing, he remarked, "Kathleen Goring tea'd with me yesterday. Of course, it was largely due to that damned orange-skin, but I—er—did not pass a sleepless night."

Which I took to be indicative of a state of mind induced by the rind of that nutritious fruit, rather than any reference to his broken leg. For when a man has passed unscathed through parachute descents and little things like that, only to lose badly on points to a piece of peel, his sense of humour gets a jog in a crucial place. And a sense of humour is fatal to the hopeless, undying passion. It is almost as fatal, in fact, as a hiccough at the wrong moment.

"It was just about half-past twelve that the train came along. I was standing by the end of the bridge, with my overcoat and rifle showing in the faint light of the moon. The engine-driver waved his arm and shouted something in greeting and I waved back. Then I took the one free lead and waited until the engine was past me. I could see the first of the guns, just coming abreast, and at that moment I connected up with the battery in my pocket. Two slabs of gun-cotton make a noise, as you know, and just as the engine reached the charge, a sheet of flame seemed to leap from underneath the front wheels. The driver hadn't time to do a thing—the engine had left the rails before he knew what had happened. And then things moved. In my wildest moments I had never expected such a success. The engine crashed through the parapet wall and hung for a moment in space. Then it fell downward into the water, and by the mercy of Allah the couplings held. The first two guns followed it, through the gap it had made, and then the others overturned with the pull before they got there, smashing down the wall the whole way along. Every single gun went wallop into the Scheldt—to say nothing of two passenger carriages containing the gunners and their officers. The whole thing was over in five seconds; and you can put your shirt on it that before the last gun hit the water yours truly had cast away his regalia of office and was legging it like a two-year-old back to the veuve Demassiet and Tournai. It struck me that bridge might shortly become an unhealthy spot."
