The mountain warfare of Italy is extraordinarily unlike that upon any other front. From the Isonzo to the Swiss frontier we are dealing with high mountains, cut by deep valleys between which there is usually no practicable lateral communication. Each advance must have the nature of an unsupported shove along a narrow channel, until the whole mountain system, that is, is won, and the attack can begin to deploy in front of the passes. Geographically Austria has the advantage. She had the gentler slope of the mountain chains while Italy has the steep side, and the foresight of old treaties has given her deep bites into what is naturally Italian territory; she is far nearer the Italian plain than Italy is near any practicable fighting ground for large forces; particularly is this the case in the region of the Adige valley and Lake Garda.
The legitimate war, so to speak, in this region is a mountaineering war. The typical position is roughly as follows. The Austrians occupy valley A which opens northward; the Italians occupy valley B which opens southward. The fight is for the crest between A and B. The side that wins that crest gains the power of looking down into, firing into and outflanking the positions of the enemy valley. In most cases it is the Italians now who are pressing, and if the reader will examine a map of the front and compare it with the official reports he will soon realise that almost everywhere the Italians are up to the head of the southward valleys and working over the crests so as to press down upon the Austrian valleys. But in the Trentino the Austrians are still well over the crest on the southward slopes. When I was in Italy they still held Rovereto.
Now it cannot be said that under modern conditions mountains favour either the offensive or the defensive. But they certainly make operations far more deliberate than upon a level. An engineered road or railway in an Alpine valley is the most vulnerable of things; its curves and viaducts may be practically demolished by shell fire or swept by shrapnel, although you hold the entire valley except for one vantage point. All the mountains round about a valley must be won before that valley is safe for the transport of an advance. But on the other hand a surprise capture of some single mountain crest and the hoisting of one gun into position there may block the retreat of guns and material from a great series of positions. Mountain surfaces are extraordinarily various and subtle. You may understand Picardy on a map, but mountain warfare is three-dimensional. A struggle may go on for weeks or months consisting of apparently separate and incidental skirmishes, and then suddenly a whole valley organisation may crumble away in retreat or disaster. Italy is gnawing into the Trentino day by day, and particularly around by her right wing. At no time I shall be surprised to see a sudden lunge forward on that front, and hear a tale of guns and prisoners. This will not mean that she has made a sudden attack, but that some system of Austrian positions has collapsed under her continual pressure.
Such briefly is the idea of mountain struggle. Its realities, I should imagine, are among the strangest and most picturesque in all this tremendous world conflict. I know nothing of the war in the east, of course, but there are things here that must be hard to beat. Happily they will soon get justice done to them by an abler pen than mine. I hear that Kipling is to follow me upon this ground; nothing can be imagined more congenial to his extraordinary power of vivid rendering than this struggle against cliffs, avalanches, frost and the Austrian.
To go the Italian round needs, among other things, a good head. Everywhere it has been necessary to make roads where hitherto there have been only mule tracks or no tracks at all; the roads are often still in the making, and the automobile of the war tourist skirts precipices and takes hairpin bends upon tracks of loose metal not an inch too broad for the operation, or it floats for a moment over the dizzy edge while a train of mule transport blunders by. The unruly imagination of man's heart (which is “only evil continually”) speculates upon what would be the consequences of one good bump from the wheel of a mule cart. Down below, the trees that one sees through a wisp of cloud look far too small and spiky and scattered to hold out much hope for a fallen man of letters. And at the high positions they are too used to the vertical life to understand the secret feelings of the visitor from the horizontal. General Bompiani, whose writings are well known to all English students of military matters, showed me the Gibraltar he is making of a great mountain system east of the Adige.
“Let me show you,” he said, and flung himself on to the edge of the precipice into exactly the position of a lady riding side-saddle. “You will find it more comfortable to sit down.”
But anxious as I am abroad not to discredit my country by unseemly exhibitions I felt unequal to such gymnastics without a proper rehearsal at a lower level. I seated myself carefully at a yard (perhaps it was a couple of yards) from the edge, advanced on my trousers without dignity to the verge, and so with an effort thrust my legs over to dangle in the crystalline air.
“That,” proceeded General Bompiani, pointing with a giddy flourish of his riding whip, “is Monte Tomba.”
I swayed and half-extended my hand towards him. But he was still there—sitting, so to speak, on the half of himself.... I was astonished that he did not disappear abruptly during his exposition....

The fighting man in the Dolomites has been perhaps the most wonderful of all these separate campaigns. I went up by automobile as far as the clambering new road goes up the flanks of Tofana No. 2; thence for a time by mule along the flank of Tofana No. 1, and thence on foot to the vestiges of the famous Castelletto.
The aspect of these mountains is particularly grim and wicked; they are worn old mountains, they tower overhead in enormous vertical cliffs of sallow grey, with the square jointings and occasional clefts and gullies, their summits are toothed and jagged; the path ascends and passes round the side of the mountain upon loose screes, which descend steeply to a lower wall of precipices. In the distance rise other harsh and desolate-looking mountain masses, with shining occasional scars of old snow. Far below is a bleak valley of stunted pine trees through which passes the road of the Dolomites.
As I ascended the upper track two bandages men were coming down on led mules. It was mid-August, and they were suffering from frostbite. Across the great gap between the summits a minute traveller with some provisions was going up by wire to some post upon the crest. For everywhere upon the icy pinnacles are observation posts directing the fire of the big guns on the slopes below, or machine-gun stations, or little garrisons that sit and wait through the bleak days. Often they have no link with the world below but a precipitous climb or a “teleferic” wire. Snow and frost may cut them off absolutely for weeks from the rest of mankind. The sick and wounded must begin their journey down to help and comfort in a giddy basket that swings down to the head of the mule track below.
Originally all these crests were in Austrian hands; they were stormed by the Alpini under almost incredible conditions. For fifteen days, for example, they fought their way up these screes on the flanks of Tofana No. 2 to the ultimate crags, making perhaps a hundred metres of ascent each day, hiding under rocks and in holes in the daylight and receiving fresh provisions and ammunition and advancing by night. They were subjected to rifle fire, machine-gun fire and bombs of a peculiar sort, big iron balls of the size of a football filled with explosive that were just flung down the steep. They dodged flares and star shells. At one place they went up a chimney that would be far beyond the climbing powers of any but a very active man. It must have been like storming the skies. The dead and wounded rolled away often into inaccessible ravines. Stray skeletons, rags of uniform, fragments of weapons, will add to the climbing interest of these gaunt masses for many years to come. In this manner it was that Tofana No. 2 was taken.
Now the Italians are organising this prize, and I saw winding up far above me on the steep grey slope a multitudinous string of little things that looked like black ants, each carrying a small bright yellow egg. They were mules bringing back balks of timber....
But one position held out invincibly; this was the Castelletto, a great natural fortress of rock standing out at an angle of the mountain in such a position that it commanded the Italian communications (the Dolomite road) in the valley below, and rendered all their positions uncomfortable and insecure. This obnoxious post was practically inaccessible either from above or below, and it barred the Italians even from looking into the Val Travenanzes which it defended. It was, in fact, an impregnable position, and against it was pitted the invincible 5th Group of the Alpini. It was the old problem of the irresistible force in conflict with the immovable object. And the outcome has been the biggest military mine in all history.
The business began in January, 1916, with surveys of the rock in question. The work of surveying for excavations, never a very simple one, becomes much more difficult when the site is occupied by hostile persons with machine guns. In March, as the winter's snows abated, the boring machinery began to arrive, by mule as far as possible and then by hand. Altogether about half a kilometre of gallery had to be made to the mine chamber, and meanwhile the explosive was coming up load by load and resting first here, then there, in discreetly chosen positions. There were at the last thirty-five tons of it in the inner chamber. And while the boring machines bored and the work went on, Lieutenant Malvezzi was carefully working out the problem of “il massimo effetto dirompimento” and deciding exactly how to pack and explode his little hoard. On the eleventh of July, at 3.30, as he rejoices to state in his official report, “the mine responded perfectly both in respect of the calculations made and of the practical effects,” that is to say, the Austrians were largely missing and the Italians were in possession of the crater of the Castelletto and looking down the Val Travenanzes from which they had been barred for so long. Within a month things had been so tidied up, and secured by further excavations and sandbags against hostile fire, that even a middle-aged English writer, extremely fagged and hot and breathless, could enjoy the same privilege. All this, you must understand, had gone on at a level to which the ordinary tourist rarely climbs, in a rarefied, chest-tightening atmosphere, with wisps of clouds floating in the clear air below and club-huts close at hand....
Among these mountains avalanches are frequent; and they come down regardless of human strategy. In many cases the trenches cross avalanche tracks; they and the men in them are periodically swept away and periodically replaced. They are positions that must be held; if the Italians will not face such sacrifices, the Austrians will. Avalanches and frostbite have slain and disabled their thousands; they have accounted perhaps for as many Italians in this austere and giddy campaign as the Austrians....

It seems to be part of the stern resolve of Fate that this, the greatest of wars, shall be the least glorious; it is manifestly being decided not by victories but by blunders. It is indeed a history of colossal stupidities. Among the most decisive of these blunders, second only perhaps of the blunder of the Verdun attack and far outshining the wild raid of the British towards Bagdad, was the blunder of the Trentino offensive. It does not need the equipment of a military expert, it demands only quite ordinary knowledge and average intelligence, to realise the folly of that Austrian adventure. There is some justification for a claim that the decisive battle of the war was fought upon the soil of Italy. There is still more justification for saying that it might have been.
There was only one good point about the Austrian thrust. No one could have foretold it. And it did so completely surprise the Italians as to catch them without any prepared line of positions in the rear. On the very eve of the big Russian offensive, the Austrians thrust eighteen divisions hard at the Trentino frontier. The Italian posts were then in Austrian territory; they held on the left wing and the right, but they were driven by the sheer weight of men and guns in the centre; they lost guns and prisoners because of the difficulty of mountain retreats to which I have alluded, and the Austrians pouring through reached not indeed the plain of Venetia, but to the upland valleys immediately above it, to Asiago and Arsiero. They probably saw the Venetian plain through gaps in the hills, but they were still separated from it even at Arsiero by what are mountains to an English eye, mountains as high as Snowdon. But the Italians of such beautiful old places and Vicenza, Marostica, and Bassano could watch the Austrian shells bursting on the last line of hills above the plain, and I have no doubt they felt extremely uneasy.
As one motors through these ripe and beautiful towns and through the rich valleys that link them—it is a smiling land abounding in old castles and villas, Vicenza is a rich museum of Palladio's architecture and Bassano is full of irreplaceable painted buildings—one feels that the things was a narrow escape, but from the military point of view it was merely an insane escapade. The Austrians had behind them—and some way behind them—one little strangulated railway and no good pass road; their right was held at Pasubio, their left was similarly bent back. In front of them was between twice and three times their number of first class troops, with an unlimited equipment. If they had surmounted that last mountain crest they would have come down to almost certain destruction in the plain. They could never have got back. For a time it was said that General Cadorna considered that possibility. From the point of view of purely military considerations, the Trentino offensive should perhaps have ended in the capitulation of Vicenza.
I will confess I am glad it did not do so. This tour of the fronts has made me very sad and weary with a succession of ruins. I can bear no more ruins unless they are the ruins of Dusseldorf, Cologne, Berlin, or suchlike modern German city. Anxious as I am to be a systematic Philistine, to express my preference for Marinetti over the Florentine British and generally to antagonise aesthetic prigs, I rejoiced over that sunlit land as one might rejoice over a child saved from beasts.
On the hills beyond Schio I walked out through the embrasure of a big gun in a rock gallery, and saw the highest points upon the hillside to which the Austrian infantry clambered in their futile last attacks. Below me were the ruins of Arsiero and Velo d'Astico recovered, and across the broad valley rose Monte Cimone with the Italian trenches upon its crest and the Austrians a little below to the north. A very considerable bombardment was going on and it reverberated finely. (It is only among mountains that one hears anything that one can call the thunder of guns. The heaviest bombardments I heard in France sounded merely like Brock's benefit on a much large scale, and disappointed me extremely.) As I sat and listened to the uproar and watched the shells burst on Cimone and far away up the valley over Castelletto above Pedescala, Captain Pirelli pointed out the position of the Austrian frontier. I doubt if the English people realise that the utmost depth to which this great Trentino offensive, which exhausted Austria, wasted the flower of the Hungarian army and led directly to the Galician disasters and the intervention of Rumania, penetrated into Italian territory was about six miles.
