‘Drive me somewhere to breakfast, Archie,’ I said, ‘for I’m perishing hungry.’

He and I got into the tonneau, and the driver swung us out of the station road up a long incline of hill. Sir Archie had been one of my subalterns in the old Lennox Highlanders, and had left us before the Somme to join the Flying Corps. I had heard that he had got his wings and had done well before Arras, and was now training pilots at home. He had been a light-hearted youth, who had endured a good deal of rough-tonguing from me for his sins of omission. But it was the casual class of lad I was looking for now.

I saw him steal amused glances at my appearance.

‘Been seein’ a bit of life, sir?’ he inquired respectfully.

‘I’m being hunted by the police,’ I said.

‘Dirty dogs! But don’t worry, sir; we’ll get you off all right. I’ve been in the same fix myself. You can lie snug in my little log hut, for that old image Gibbons won’t blab. Or, tell you what, I’ve got an aunt who lives near here and she’s a bit of a sportsman. You can hide in her moated grange till the bobbies get tired.’

I think it was Archie’s calm acceptance of my position as natural and becoming that restored my good temper. He was far too well bred to ask what crime I had committed, and I didn’t propose to enlighten him much. But as we swung up the moorland road I let him know that I was serving the Government, but that it was necessary that I should appear to be unauthenticated and that therefore I must dodge the police. He whistled his appreciation.

‘Gad, that’s a deep game. Sort of camouflage? Speaking from my experience it is easy to overdo that kind of stunt. When I was at Misieux the French started out to camouflage the caravans where they keep their pigeons, and they did it so damned well that the poor little birds couldn’t hit ’em off, and spent the night out.’

We entered the white gates of a big aerodrome, skirted a forest of tents and huts, and drew up at a shanty on the far confines of the place. The hour was half past four, and the world was still asleep. Archie nodded towards one of the hangars, from the mouth of which projected the propeller end of an aeroplane.

‘I’m by way of flyin’ that bus down to Farnton tomorrow,’ he remarked. ‘It’s the new Shark–Gladas. Got a mouth like a tree.’

An idea flashed into my mind.

‘You’re going this morning,’ I said.

‘How did you know?’ he exclaimed. ‘I’m due to go today, but the grouse up in Caithness wanted shootin’ so badly that I decided to wangle another day’s leave. They can’t expect a man to start for the south of England when he’s just off a frowsy journey.’

‘All the same you’re going to be a stout fellow and start in two hours’ time. And you’re going to take me with you.’

He stared blankly, and then burst into a roar of laughter. ‘You’re the man to go tiger-shootin’ with. But what price my commandant? He’s not a bad chap, but a trifle shaggy about the fetlocks. He won’t appreciate the joke.’

‘He needn’t know. He mustn’t know. This is an affair between you and me till it’s finished. I promise you I’ll make it all square with the Flying Corps. Get me down to Farnton before evening, and you’ll have done a good piece of work for the country.’

‘Right-o! Let’s have a tub and a bit of breakfast, and then I’m your man. I’ll tell them to get the bus ready.’

In Archie’s bedroom I washed and shaved and borrowed a green tweed cap and a brand-new Aquascutum. The latter covered the deficiencies of my raiment, and when I commandeered a pair of gloves I felt almost respectable. Gibbons, who seemed to be a jack-of-all-trades, cooked us some bacon and an omelette, and as he ate Archie yarned. In the battalion his conversation had been mostly of race-meetings and the forsaken delights of town, but now he had forgotten all that, and, like every good airman I have ever known, wallowed enthusiastically in ‘shop’. I have a deep respect for the Flying Corps, but it is apt to change its jargon every month, and its conversation is hard for the layman to follow. He was desperately keen about the war, which he saw wholly from the viewpoint of the air. Arras to him was over before the infantry crossed the top, and the tough bit of the Somme was October, not September. He calculated that the big air-fighting had not come along yet, and all he hoped for was to be allowed out to France to have his share in it. Like all good airmen, too, he was very modest about himself. ‘I’ve done a bit of steeple-chasin’ and huntin’ and I’ve good hands for a horse, so I can handle a bus fairly well. It’s all a matter of hands, you know. There ain’t half the risk of the infantry down below you, and a million times the fun. Jolly glad I changed, sir.’

We talked of Peter, and he put him about top. Voss, he thought, was the only Boche that could compare with him, for he hadn’t made up his mind about Lensch. The Frenchman Guynemer he ranked high, but in a different way. I remember he had no respect for Richthofen and his celebrated circus.

At six sharp we were ready to go. A couple of mechanics had got out the machine, and Archie put on his coat and gloves and climbed into the pilot’s seat, while I squeezed in behind in the observer’s place. The aerodrome was waking up, but I saw no officers about. We were scarcely seated when Gibbons called our attention to a motor-car on the road, and presently we heard a shout and saw men waving in our direction.

‘Better get off, my lad,’ I said. ‘These look like my friends.’

The engine started and the mechanics stood clear. As we taxied over the turf I looked back and saw several figures running in our direction. The next second we had left the bumpy earth for the smooth highroad of the air.

I had flown several dozen times before, generally over the enemy lines when I wanted to see for myself how the land lay. Then we had flown low, and been nicely dusted by the Hun Archies, not to speak of an occasional machine-gun. But never till that hour had I realized the joy of a straight flight in a swift plane in perfect weather. Archie didn’t lose time. Soon the hangars behind looked like a child’s toys, and the world ran away from us till it seemed like a great golden bowl spilling over with the quintessence of light. The air was cold and my hands numbed, but I never felt them. As we throbbed and tore southward, sometimes bumping in eddies, sometimes swimming evenly in a stream of motionless ether, my head and heart grew as light as a boy’s. I forgot all about the vexations of my job and saw only its joyful comedy. I didn’t think that anything on earth could worry me again. Far to the left was a wedge of silver and beside it a cluster of toy houses. That must be Edinburgh, where reposed my portmanteau, and where a most efficient police force was now inquiring for me. At the thought I laughed so loud that Archie must have heard me. He turned round, saw my grinning face, and grinned back. Then he signalled to me to strap myself in. I obeyed, and he proceeded to practise ‘stunts’— the loop, the spinning nose-dive, and others I didn’t know the names of. It was glorious fun, and he handled his machine as a good rider coaxes a nervous horse over a stiff hurdle. He had that extra something in his blood that makes the great pilot.

Presently the chessboard of green and brown had changed to a deep purple with faint silvery lines like veins in a rock. We were crossing the Border hills, the place where I had legged it for weary days when I was mixed up in the Black Stone business. What a marvellous element was this air, which took one far above the fatigues of humanity! Archie had done well to change. Peter had been the wise man. I felt a tremendous pity for my old friend hobbling about a German prison-yard, when he had once flown a hawk. I reflected that I had wasted my life hitherto. And then I remembered that all this glory had only one use in war and that was to help the muddy British infantryman to down his Hun opponent. He was the fellow, after all, that decided battles, and the thought comforted me.

A great exhilaration is often the precursor of disaster, and mine was to have a sudden downfall. It was getting on for noon and we were well into England — I guessed from the rivers we had passed that we were somewhere in the north of Yorkshire — when the machine began to make odd sounds, and we bumped in perfectly calm patches of air. We dived and then climbed, but the confounded thing kept sputtering. Archie passed back a slip of paper on which he had scribbled: ‘Engine conked. Must land at Micklegill. Very sorry.’ So we dropped to a lower elevation where we could see clearly the houses and roads and the long swelling ridges of a moorland country. I could never have found my way about, but Archie’s practised eye knew every landmark. We were trundling along very slowly now, and even I was soon able to pick up the hangars of a big aerodrome.

We made Micklegill, but only by the skin of our teeth. We were so low that the smoky chimneys of the city of Bradfield seven miles to the east were half hidden by a ridge of down. Archie achieved a clever descent in the lee of a belt of firs, and got out full of imprecations against the Gladas engine. ‘I’ll go up to the camp and report,’ he said, ‘and send mechanics down to tinker this darned gramophone. You’d better go for a walk, sir. I don’t want to answer questions about you till we’re ready to start. I reckon it’ll be an hour’s job.’

The cheerfulness I had acquired in the upper air still filled me. I sat down in a ditch, as merry as a sand-boy, and lit a pipe. I was possessed by a boyish spirit of casual adventure, and waited on the next turn of fortune’s wheel with only a pleasant amusement.

That turn was not long in coming. Archie appeared very breathless.

‘Look here, sir, there’s the deuce of a row up there. They’ve been wirin’ about you all over the country, and they know you’re with me. They’ve got the police, and they’ll have you in five minutes if you don’t leg it. I lied like billy-o and said I had never heard of you, but they’re comin’ to see for themselves. For God’s sake get off . . . You’d better keep in cover down that hollow and round the back of these trees. I’ll stay here and try to brazen it out. I’ll get strafed to blazes anyhow . . . I hope you’ll get me out of the scrape, sir.’

‘Don’t you worry, my lad,’ I said. ‘I’ll make it all square when I get back to town. I’ll make for Bradfield, for this place is a bit conspicuous. Goodbye, Archie. You’re a good chap and I’ll see you don’t suffer.’

I started off down the hollow of the moor, trying to make speed atone for lack of strategy, for it was hard to know how much my pursuers commanded from that higher ground. They must have seen me, for I heard whistles blown and men’s cries. I struck a road, crossed it, and passed a ridge from which I had a view of Bradfield six miles off. And as I ran I began to reflect that this kind of chase could not last long. They were bound to round me up in the next half-hour unless I could puzzle them. But in that bare green place there was no cover, and it looked as if my chances were pretty much those of a hare coursed by a good greyhound on a naked moor.

Suddenly from just in front of me came a familiar sound. It was the roar of guns — the slam of field-batteries and the boom of small howitzers. I wondered if I had gone off my head. As I plodded on the rattle of machine-guns was added, and over the ridge before me I saw the dust and fumes of bursting shells. I concluded that I was not mad, and that therefore the Germans must have landed. I crawled up the last slope, quite forgetting the pursuit behind me.

And then I’m blessed if I did not look down on a veritable battle.

There were two sets of trenches with barbed wire and all the fixings, one set filled with troops and the other empty. On these latter shells were bursting, but there was no sign of life in them. In the other lines there seemed the better part of two brigades, and the first trench was stiff with bayonets. My first thought was that Home Forces had gone dotty, for this kind of show could have no sort of training value. And then I saw other things — cameras and camera-men on platforms on the flanks, and men with megaphones behind them on wooden scaffoldings. One of the megaphones was going full blast all the time.

I saw the meaning of the performance at last. Some movie-merchant had got a graft with the Government, and troops had been turned out to make a war film. It occurred to me that if I were mixed up in that push I might get the cover I was looking for. I scurried down the hill to the nearest camera-man.

As I ran, the first wave of troops went over the top. They did it uncommon well, for they entered into the spirit of the thing, and went over with grim faces and that slow, purposeful lope that I had seen in my own fellows at Arras. Smoke grenades burst among them, and now and then some resourceful mountebank would roll over. Altogether it was about the best show I have ever seen. The cameras clicked, the guns banged, a background of boy scouts applauded, and the dust rose in billows to the sky.

But all the same something was wrong. I could imagine that this kind of business took a good deal of planning from the point of view of the movie-merchant, for his purpose was not the same as that of t............
