Now we were well within the danger zone. I knew it by the screens of woven reeds and grass matting which had been erected along one side of the road in order to protect the troops and transport using that road from being seen by the Austrian observers and shelled by the Austrian guns. Practically all of the roads on the Italian side of the front are, remember, under direct observation by the Austrians. In fact, they command everything. Everywhere they are above the Italians. From the observatories which they have established on every peak they can see through their powerful telescopes what is transpiring down on the plain as readily as though they were circling above it in an airplane. As a result of the extraordinary advantage which the Austrians enjoy in this respect, it has been found necessary to screen certain of the roads not only on both sides but above, so that in places the traffic passes for miles through literal tunnels of matting. This road masking is a simple form of the art of concealment to which the French have given the name "camouflage," which has been developed to an extraordinary degree on the Western Front. That the Italians have not made a greater use of it is due, no doubt, to the wholly different conditions under which they are fighting.
Now the crowded road that we were following turned sharply into a narrow valley, down which a small river twisted and turned on its way to the sea. Though the Italian positions ran along the top of the hill slope just above us, and though less than a thousand yards away were the Austrian trenches, that valley, for many miles, was literally crawling with men and horses and guns. Indeed it was difficult to make myself believe that we were within easy range of the enemy and that at any instant a shell might fall upon that teeming hillside and burst with the crash that scatters death.
Despite the champagne-cork popping of the rifles and the basso profundo of the guns, it was a scene of ordered, yes, almost peaceful industry which in no way suggested war but reminded me, rather, of the Panama Canal at the busiest period of its construction (I have used the simile before, but I use it again because I know none better), of the digging of the New York subway, of the laying of a transcontinental railway, of the building of the dam at Assuan. Trenches which had recently been captured from the Austrians were being cleared and renovated and new trenches were being dug, roads were being repaired, a battery of monster howitzers was being moved into ingeniously concealed positions, a whole system of narrow-gauge railway was being laid down, enormous quantities of stores were being unloaded from wagons and lorries and neatly stacked, soldiers were building great water-tanks on stilts, like those at railway sidings, giant shells were being lowered from trucks and flat-cars by means of cranes; to the accompaniment of saws and hammers a city of wooden huts was springing up on the reverse slope of the hill as though at the wave of a magician's wand.
As I watched with fascinated eyes this scene of activity, as city idlers watch the laborers at work in a cellar excavation, a shell burst on the crowded hillside, perhaps five hundred yards away. There was a crash like the explosion of a giant cannon-cracker; the ground leaped into flame and dust. A few minutes afterward I saw an ambulance go tearing up the road.
"Just a chance shot," said the staff-officer who accompanied me. "This valley is one of the few places on our front which is invisible to the Austrian observers. That's why we have so many troops in here. The Austrian aviators could spot what is going on here, of course, but our fliers and our anti-aircraft batteries have been making things so hot for them lately that they're not troubling us much. That's the great thing in this game—to keep control of the air. If the Austrian airmen were able to get over this valley and direct the fire of their guns we wouldn't be able to stay here an hour."
My companion had thought that it might be possible to follow the road down the valley to Monfalcone and the sea, and so it would have been had the weather continued misty and rainy. But the sun came out brightly just as we reached the beginning of an exposed stretch of the road; an Austrian observer, peering through a telescope set up in a monastery on top of a mountain ten miles away, caught sight of the hurrying gray insect which was our car; he rang up on the telephone a certain battery and spoke a few words to the battery commander; and an instant later on the road along which we were travelling Austrian shells began to fall. Shells being expensive, that little episode cost the Emperor-King several hundred kronen, we figured. As for us, it merely interrupted a most interesting morning's ride.
Leaving the car in the shelter of a hill, we toiled up a steep and stony slope to a point from which I was able to get an admirable idea of the general lay of Italy's Eastern Front. Coming toward me was the Isonzo—a bright blue stream the width of the Thames at New London—which, happy at escaping from its gloomy mountain defile, went rioting over the plain in a great westward curve. Turning, I could catch a glimpse, through a notch in the hills, of the white towers and pink roofs of Monfalcone against the Adriatic's changeless blue. To the east of Monfalcone rose the red heights of the Carso, the barren limestone plateau which stretches from the Isonzo south into Istria. And beyond the Carso I could trace the whole curve of the mountains from in front of Trieste up past Gorizia and away to the Carnia. The Italian front, I might add, divides itself into four sectors: the Isonzo, the Carnia and Cadore, the Trentino, and the Alpine.
Directly below us, not more than a kilometre away, was a village which the Austrians were shelling. Through our glasses we could see the effects of the bombardment as plainly as though we had been watching a football game from the upper tier of seats in the Yale Bowl. They were using a considerable number of guns of various calibers and the crash of the bursting shells was almost incessant. A shell struck a rather pretentious building, which was evidently the town hall; there was a burst of flame, and a torrent of bricks and beams and tiles shot skyward amid a geyser of green-brown smoke. Another projectile chose as its target the tall white campanile, which suddenly slumped into the street, a heap of brick and plaster. Now and again we caught glimpses of tiny figures—Italian soldiers, most likely—scuttling for shelter. Occasionally the Austrians would vary their rain of heavy projectiles with a sort of shell that went bang and released a fleecy cloud of smoke overhead and then dropped a parcel of high explosive that burst on the ground. It was curious to think that the guns from which these shells came were cunningly hidden away in nooks and glens on the other side of that distant range of hills, that the men serving the guns had little if any idea what they were firing at, and that the bombardment was being directed and controlled by an officer seated comfortably at the small end of a telescope up there on a mountain top among the clouds. Yet such is modern war. It used to be one of the artillerist's tenets that his guns should be placed in a position with a "commanding" range of view. But nowadays guns "command" nothing. Instead they are tucked away in gullies and leafy glens and excavated gun-pits, and their muzzles, instead of frowning down on the enemy from an eminence, stare blindly skyward from behind a wall of hills or mountains. The Italians evidently grew tired of letting the Austrians have their way with the town, for presently some batteries of heavy guns behind us came into action and their shells screamed over our heads. Soon a brisk exchange of compliments between the Italian and Austrian guns was going on over the shattered roofs of the town. We did not remain overlong on our hillside and we were warned by the artillery officer who was guiding us to keep close to the ground and well apart, for, were the Austrians to see us in a group, using maps and field-glasses, they probably would take us for artillery observers and would send over a violent protest cased in steel.
On none of the European battle-fronts is there a more beautiful and impressive journey than that from Udine up to the Italian positions in the Carnia. The Carnia sector connects the Isonzo and Trentino fronts and forms a vital link in the Italian chain of defense, for, were the Austrians to break through, they would take in flank and rear the great Italian armies operating on the two adjacent fronts. West of the Carnia, in Cadore, the Italians are campaigning in one of the world's most famous playgrounds, for, in the days before the Great War, pleasure-seekers from every corner of Europe and America swarmed by the tens of thousands in the country round about Cortina and in the enchanted valleys of the Dolomites. But now great gray guns are emplaced in the shady glens where the honeymooners used to stroll; on the terraces of the tourist hostelries, where, on summer afternoons, men in white flannels and women in dainty frocks chattered over their tea, now lounge Italian officers in field uniforms of gray; the blare of dance music and the popping of champagne corks has been replaced by the blare of bugles and the popping of rifles.
