CHAPTER IV.

SPYING OUT THE LAND.

For thirty hours the flight had "stood by" for a long reconnaissance. We

were dragged from bed at 4.30 of dawn, only to return gratefully beneath

the blankets three-quarters of an hour later, when a slight but steady

rain washed away all chance of an immediate job. The drizzle continued

until after sundown, and our only occupations throughout the day were to

wade from mess to aerodrome, aerodrome to mess, and to overhaul in

detail machines, maps, guns, and consciences.

Next morning again we dressed in the half-light, and again went back to

bed in the daylight. This time the show had been postponed because of

low clouds and a thick ground-mist that hung over the reeking earth. It

was a depressing dawn--clammy, moist, and sticky.

But by early afternoon the mist had congealed, and the sheet of clouds

was torn to rags by a strong south-west wind. The four craft detailed

for the reconnaissance were therefore lined outside their shed, while

their crews waited for flying orders. I was to be in the leading bus,

for when C.'s death left vacant the command of A Flight, the good work

of my pilot had brought him a flight-commandership, a three-pipped

tunic, and a sense of responsibility which, to my relief, checked his

tendency to over-recklessness. He now came from the squadron office with

news of a changed course.

"To get the wind behind us," he explained, "we shall cross well to the

south of Peronne. Next, we go to Boislens. After that we pass by

Nimporte, over the Foret de Charbon to Siegecourt; then up to Le Recul

and back by Princebourg, St. Guillaume, and Toutpres.

"As regards the observers, don't forget to use your field-glasses on the

rolling stock; don't forget the precise direction of trains and motor

transport; don't forget the railways and roads on every side; don't

forget the canals; and for the Lord's and everybody else's sake, don't

be surprised by Hun aircraft. As regards the pilots--keep in close

formation when possible; don't straggle and don't climb above the proper

height."

The pilots ran their engines once more, and the observers exchanged

information about items such as Hun aerodromes and the number of railway

stations at each large town. An air reconnaissance is essentially the

observer's show; its main object being to supply the "I" people at

headquarters with private bulletins from the back of the German front.

The collection of reconnaissance reports is work of a highly skilled

nature, or ought to be. Spying out the land is much more than a search

of railways, roads, and the terrain generally. The experienced observer

must know the German area over which he works rather better than he

knows Salisbury Plain. The approximate position of railway junctions and

stations, aerodromes, factories, and depots should be familiar to him,

so that he can without difficulty spot any new feature. Also he must be

something of a sleuth, particularly when using smoke as a clue. In the

early morning a thin layer of smoke above a wood may mean a bivouac. If

it be but a few miles behind the lines, it can evidence heavy artillery.

A narrow stream of smoke near a railway will make an observer scan the

line closely for a stationary train, as the Boche engine-drivers usually

try to avoid detection by shutting off steam. The Hun has many other

dodges to avoid publicity. When Allied aircraft appear, motor and horse

transport remain immobile at the roadside or under trees. Artillery and

infantry are packed under cover; though, for that matter, the enemy very

rarely move troops in the daytime, preferring the night or early

morning, when there are no troublesome eyes in the air.

To foil these attempts at concealment is the business of the observers

who gather information for Army Headquarters and G. H.Q. For observers

on corps work the detective problems are somewhat different. This

department deals with hidden saps and battery positions, and draws and

photographs conclusions from clues such as a muzzle-blast, fresh tracks,

or an artificial cluster of trees. All reconnaissance observers must

carry out a simultaneous search of the earth for movement and the sky

for foes, and in addition keep their guns ready for instant use. And

should anything happen to their machines, and a forced landing seem

likely, they must sit tight and carry on so long as there is the

slightest hope of a safe return.

A nos moutons. I made a long list in my note-book of the places where

something useful was likely to be observed, and tried my gun by firing a

few shots into the ground. We hung around, impatient at the long delay.

"Get into your machines," called the Squadron Commander at last, when a

telephone message had reported that the weather conditions toward the

east were no longer unfavourable. We took to the air and set off.

V. led his covey beyond Albert and well south of the Somme before he

turned to the left. Then, with the strong wind behind us, we raced

north-east and crossed the strip of trenches. The pilot of the emergency

machine, which had come thus far to join the party if one of the other

four dropped out, waved his hand in farewell and left for home.

Archie barked at us immediately, but he caused small trouble, as most of

his attention was already claimed by a party of French machines half a

mile ahead. Anyhow we should have shaken him off quickly, for at this

stage of the journey, with a forty-mile wind reinforcing our usual air

speed of about ninety-five miles an hour, our ground speed was

sufficient to avoid lingering in any region made unhealthy by A.-A.

guns. The water-marked ribbon of trenches seemed altogether puny and

absurd during the few seconds when it was within sight. The winding

Somme was dull and dirty as the desolation of its surrounding basin.

Some four thousand feet above the ground a few clouds moved restlessly

at the bidding of the wind.

Passing a few small woods, we arrived without interruption over the

railway junction of Boislens. With arms free of the machine to avoid

unnecessary vibration, the observers trained their glasses on the

station and estimated the amount of rolling stock. A close search of the

railway arteries only revealed one train. I grabbed pencil and

note-book and wrote: "Boislens, 3.5 P.M. 6 R.S., 1 train going

S.W."

Just west of our old friend Mossy-Face were two rows of flagrantly new

trenches. As this is one of the points where the enemy made a stand

after their 1917 spring retreat, it can be assumed that even as far back

as last October they were preparing new lines of defence, Hindenburg or

otherwise. Not far west of these defence works were two troublesome

aerodromes at Bertincourt and Velu, both of which places have since been

captured.

A hunt for an aerodrome followed. V., who knew the neighbourhood well,

having passed above it some two-score times, was quick to spot a group

of hitherto unnoted sheds north of Boislens, towards Mossy-Face. He

circled over them to let me plot the pin-point position on the map and

sketch the aerodrome and its surroundings. The Hun pilots, with thoughts

of a possible bomb-raid, began to take their machines into the air for

safety.

"Got 'em all?" Thus V., shouting through the rubber speaking-tube, one

end of which was fixed inside my flying-cap, so that it always rested

against my ear.

"Correct. Get on with the good work."

The good work led us over a region for ever associated with British

arms. Some of the towns brought bitter memories of that anxious August

three years back. Thus Nimporte, which saw a desperate but successful

stand on one flank of the contemptible little army to gain time for the

main body; Ventregris, scene of a cavalry charge that was a glorious

tragedy; Labas, where a battery of horse-gunners made for itself an

imperishable name; Siegecourt, where the British might have retired into

a trap but didn't; and Le Recul itself, whence they slipped away just in

time.

In the station at Nimporte a train was waiting to move off, and two more

were on their way to the military base of Pluspres. Both attempted to

hide their heads by shutting off steam immediately the drone of our

engines made itself heard; but we had spotted them from afar, and

already they were noted for the information of Brass Hats.

The next item of interest was activity at a factory outside a little

town. Black trails of smoke stretched away from the chimneys; and

surely, as we approached a minute ago, a short column of lorries was

passing along a road towards the factory. Yet when we reached the spot

there was no sign of road transport. Nevertheless, I was certain I had

seen some motor vehicles, and I entered the fact in my note-book.

Likewise I took care to locate the factory site on my map, in case it

deserved the honour of a bomb attack later.

Our bus led the way across the huge unwieldy Foret de Charbon, patterned

in rectangular fashion by intersecting roads, and we arrived at

Siegecourt. This is at once a fortress and an industrial town. There are

several railway stations around it, and these added greatly to the

observers' collection of trains and trucks. The Huns below, with

unpleasant memories of former visits from British aircraft, probably

expected to be bombed. They threw up at us a large quantity of

high-explosive shells, but the shots were all wide and we remained

unworried. To judge by the quality of the A.-A. shooting each time I

called there, it seemed likely that half-trained A.-A. gunners were

allowed to cut their active service teeth on us at Siegecourt.

Having squeezed Siegecourt of all movement, we headed for Le Recul. Here

the intricate patchwork of railway kept the observers busy, and six more

trains were bagged. Then, as this was the farthest point east to be

touched, we turned to the left and travelled homeward.

It was soon afterwards that our engine went dud. Instead of a rhythmic

and continuous hum there was at regular intervals a break, caused by one

of the cylinders missing explosion at each turn of the rotary engine.

The rev.-counter showed that the number of revolutions per minute had

fallen off appreciably. Decreased revs. meant less speed, and our only

chance to keep with the others was to lose height continuously. We were

then nearly fifty miles from the lines.

I noticed the gap in the engine's drone as soon as it began. An airman

is accustomed to the full roar of his engine, and it never distracts

his attention, any more than the noise of a waterfall distracts those

who live near it. But if the roar becomes non-continuous and irregular

he is acutely conscious of the sound.

When the machine began to lose height I knew there was a chronic miss.

V. looked round and smiled reassuringly, though he himself was far from

reassured. He tried an alteration in the carburettor mixture, but this

did not remedy matters. Next, thinking that the engine might have been

slightly choked, he cut off the petrol supply for a moment and put down

the nose of the machine. The engine stopped, but picked up when the

petrol was once more allowed to run. During the interval I thought the

engine had ceased work altogether, and was about to stuff things into my

pocket in readiness for a landing on hostile ground.

We continued in a westerly direction, with the one cylinder still

cutting out. To make matters worse, the strong wind that had been our

friend on the outward journey was now an enemy, for it was drifting us

to the north, so that we were obliged to steer almost dead into it to

follow the set course.

As we passed along the straight canal from Le Recul to Princebourg many

barges were in evidence. Those at the side of the canal were taken to be

moored up, and those in the middle to be moving, though the slowness of

their speed made it impossible to decide on their direction, for from a

height of ten thousand feet they seemed to be stationary. About a dozen

Hun machines were rising from aerodromes at Passementerie, away to the

left, but if they were after us the attempt to reach our height in time

was futile.

Between Le Recul and Princebourg we dropped fifteen hundred feet below

the three rear machines, which hovered above us. Though I was far from

feeling at home, it was necessary to sweep the surrounding country for

transport of all kinds. This was done almost automatically, since I

found myself unable to give a whole-hearted attention to the job, while

the infernal motif of the engine's rag-time drone dominated everything

and invited speculation on how much lower we were than the others, and

whether we were likely to reach a friendly landing-ground. And all the

while a troublesome verse chose very inopportunely to race across the

background of my mind, in time with the engine, each cut-out being the

end of a line. Once or twice I caught myself murmuring--

"In that poor but honest 'ome,

Where 'er sorrowin' parints live,

They drink the shampyne wine she sends,

But never, never can fergive."

Slightly to the east of Princebourg, a new complication appeared in the

shape of a small German machine. Seeing that our bus was in

difficulties, it awaited an opportunity to pounce, and remained at a

height slightly greater than ours, but some distance behind the bus that

acted as rearguard to the party. Its speed must have been about ten

miles an hour more than our own, for though the Hun pilot had probably

throttled down, he was obliged to make his craft snake its way in short

curves, so that it should not come within dangerous range of our guns.

At times he varied this method by lifting the machine almost to stalling

point, letting her down again, and repeating the process. Once I saw

some motor transport on a road. I leaned over the side to estimate their

number, but gave up the task of doing so with accuracy under the double

strain of watching the Hun scout and listening to the jerky voice of the

engine.

As we continued to drop, the German evidently decided to finish us. He

climbed a little and then rushed ahead. I fired at him in rapid bursts,

but he kept to his course. He did not come near enough for a dive,

however, as the rest of the party, two thousand feet above, had watched

his movements, and as soon as he began to move nearer two of them fell

towards him. Seeing that his game was spoiled the Boche went down

steeply, and only flattened out when he was low enough to be safe from

attack.

Near St Guillaume an anti-aircraft battery opened fire. The Hun pilot

then thought it better to leave Archie to deal with us, and he annoyed

us no more. Some of the shell-bursts were quite near, but we could not

afford to lose height in distance-dodging, with our machine in a dubious

condition twenty-five miles on the wrong side of the trenches.

Toutpres, to the south-west, was to have been included in the list of

towns covered, but under the adverse circumstances V. decided not to

battle against the wind more than was necessary to get us home. He

therefore veered to the right, and steered due west. The south-west wind

cut across and drifted us, so that our actual course was north-west. Our

ground speed was now a good deal greater than if we had travelled

directly west, and there was no extra distance to be covered, because of

a large eastward bend in the lines as they wound north. We skirted the

ragged Foret de Quand-Meme, and passed St Guillaume on our left.

The behaviour of the engine went from bad to worse, and the vibration

became more and more intense. Once again I thought it would peter out

before we were within gliding distance of British territory, and I

therefore made ready to burn the machine--the last duty of an airman let

in for the catastrophe of a landing among enemies. But the engine kept

alive, obstinately and unevenly. V. held down the nose of the machine

still farther, so as to gain the lines in the quickest possible time.

Soon we were treated to a display by the family ghost of the clan

Archibald, otherwise an immense pillar of grey-white smoky substance

that appeared very suddenly to windward of us. It stretched up

vertically from the ground to a height about level with ours, which was

then only five and a half thousand feet. We watched it curiously as it

stood in an unbending rigidity similar to that of a giant waxwork, cold,

unnatural, stupidly implacable, half unbelievable, and wholly

ridiculous. At the top it sprayed round, like a stick of asparagus. For

two or three months similar apparitions had been exhibited to us at rare

intervals, nearly always in the same neighbourhood. At first sight the

pillars of smoke seemed not to disperse, but after an interval they

apparently faded away as mysteriously as they had appeared. What was

meant to be their particular branch of frightfulness I cannot say. One

rumour was that they were an experiment in aerial gassing, and another

that they were of some phosphorous compound. All I know is that they

entertained us from time to time, with no apparent damage.

Archie quickly distracted our attention from the phantom pillar. We had

been drifted to just south of Lille, possibly the hottest spot on the

whole western front as regards anti-aircraft fire. Seeing one machine

four to five thousand feet below its companions, the gunners very

naturally concentrated on it. A spasmodic chorus of barking coughs

drowned the almost equally spasmodic roar of the engine. V. dodged

steeply and then raced, full out, for the lines. A sight of the dirty

brown jig-saw of trenches heartened us greatly. A few minutes later we

were within gliding distance of the British front. When we realised that

even if the engine lost all life we could reach safety, nothing else

seemed to matter, not even the storm of shell-bursts.

Suddenly the machine quivered, swung to the left, and nearly put itself

in a flat spin. A large splinter of H.E. had sliced away part of the

rudder. V. banked to prevent an uncontrolled side-slip, righted the bus

as far as possible, and dived for the lines. These we passed at a great

pace, but we did not shake off Archie until well on the right side, for

at our low altitude the high-angle guns had a large radius of action

that could include us. However, the menacing coughs finally ceased to

annoy, and our immediate troubles were over. The strain snapped, the air

was an exhilarating tonic, the sun was warmly comforting, and everything

seemed attractive, even the desolated jumble of waste ground below us. I

opened a packet of chocolate and shared it with V., who was trying hard

to fly evenly with an uneven rudder. I sang to him down the

speaking-tube, but his nerves had stood enough for the day, and he

wriggled the machine from one side to the other until I became silent.

Contrariwise to the last, our engine recovered slightly now that its

recovery was not so important, and it behaved well until it seized up

for better or worse when we had landed.

From the aerodrome the pilots proceeded to tea and a bath, while we, the

unfortunate observers, copied our notes into a detailed report,

elaborated the sketches of the new aerodromes, and drove in our unkempt

state to Headquarters, there to discuss the reconnaissance with

spotlessly neat staff officers. At the end of the report one must give

the height at which the job was done, and say whether the conditions

were favourable or otherwise for observation. I thought of the absence

of thick clouds or mist that might have made the work difficult. Then I

thought of the cylinder that missed and the chunk of rudder that was

missing, but decided that these little inconveniences were unofficial.

And the legend I felt in duty bound to write was: "Height 5,000-10,000

ft. Observation easy."
