BLOWING UP THE CASTELLETTO

It was about the middle of last July that the laconic Italian bulletin

recorded, in effect, that the blowing of the top off a certain

mountain in the Dolomite region had been accomplished with complete

success, and that a considerable extension of line had been possible

as a consequence.

That was about all there was to it, I believe; and yet the wonder

engendered by the superb audacity of the thing had haunted me from the

first. There was no suggestion of a hint of how it was done, or even

why it was done. All that was left to the imagination, and the

result--in my own case at least--was the awakening of a burning

interest in the ways of the warriors who were wont to throw mountain

peaks and fragments of glacier at one another as the everyday

plains-bred soldier throws hand-grenades, which, waxing rather than

waning as the weeks went by, finally impelled me to attempt a visit to

the Austro-Italian Alpine Front at a time of year when the weather

conditions threatened to be all but, if not quite, prohibitive.

“With twenty-five degrees of frost at sea-level in France,” observed a

French officer at Amiens to whom I confided the plan, “what do you

expect to find at 10,000 feet on the Tyrol?”

“A number of things which they don’t do at sea-level in France or

anywhere else,” I replied, “but especially _why_ they blow the tops

off mountain peaks, and _how_ they blow the tops off mountain peaks.”

Even in Rome and Milan (though there were some who claimed social

acquaintance with the Titans who had been conforming Alpine scenery to

tactical exigency), they still spoke vaguely of the thing as

“_fantastico_” and “_incredibile_,” as men might refer to operations

in the Mountains of the Moon.

But once in the Zona di Guerra, with every rift in the lowering

cloud-blanket that so loves to muffle the verdant plain of Venezia in

its moist folds revealing (in the imminent loom of the snowy barrier

rearing itself against the cobalt of the northern sky) evidence that

the “mountain-top” part of the story had at least some foundation of

fact, whether the “blowing off” part did or not, things took on a

different aspect. On my very first day at General Headquarters I met

officers who claimed to have seen with their own eyes a mountain whose

top had been blown off; indeed, they even mentioned the names of the

_montagna mutilati_, showed me where they were on the map, pointed out

the strategical advantages which had already accrued from taking them,

and those which might be expected to accrue later.

They were still there, I was assured, even if their tops had been

blown off. They were still held by the Alpini. Two of the most

important of them were not so far away; indeed, both could be plainly

seen from where we were--if other and nearer mountains did not stand

between, and, of course, if the accursed storm-clouds would only lift.

And so, at last, the names of Castelletto and Col di Lano took

sharpened shape as something more than mystic symbols.

“But can I not go and see them?” I asked. “You have told me _why_ you

blew them up, but not _how_; yet that is the very thing that I came

out to find about at first hand.”

They shook their heads dubiously. “Not while this weather lasts,” one

of them said. “It has snowed in the Alps every day for over a month.

The _valangas_ are coming down everywhere, and (even if you were

willing to risk being buried under one of them) the roads in places

will not be open for weeks. You might wait here a month or so, and

even then be disappointed so far as getting about on the Alpine Front

is concerned. Best see what you can of the Isonzo Front now and come

back for the Alps in the spring.”

That seemed to settle it so far as seeing the Castelletto and Col di

Lano was concerned. Regarding the way in which they were mined,

however, one of the officers at the Ufficio Stampa said that he would

endeavour to arrange to have the Castelletto--much the greater

operation of the two--report put at my disposal, as well as a set of

photographs which had been taken to show the progress of this mighty

work.

“We have never given out any of the photographs before,” he said, “and

only portions of the report; but since you came to Italy on purpose to

learn about the mountain whose top was blown off, the Comando Supremo

may be moved to make a special dispensation in your favour.”

Exclusive permission to make use of both report and photographs was

granted me in due time, and since the former makes clear both the

“why” and the “how” of the unprecedented Castelletto operation, it

will perhaps be best to summarise it first as a sort of drab

background for the more vivid and intimate personal details which a

lucky turn of the fitful weather vane made it possible for me to

obtain later.

The first part of the report, by the Colonel commanding the Alpini

Group, makes plain why the mining of the Castelletto became a _sine

quâ non_ to further progress in this important sector.

“In the month of October, 1915,” he writes, “I was charged with the

carrying out of an attack with two battalions of Alpini against the

positions of Castelletto and Forcella Bois. This was the fourth time,

if I am not mistaken, that an attempt on these positions had been

made. In spite of the fact that the artillery preparation of the

opening day had been excellently performed I discovered, on the

evening of October 17, when I moved with my troops to the attack, that

its work had been absolutely of no avail.

“Having received orders at midnight to proceed to Vervei, where the

two battalions above mentioned were to take part in another operation,

I was forced to abandon the attack. I am convinced, however, that I

would not have succeeded in capturing the Castelletto position.”

“As known,” the report continues, “the Castelletto is a sort of a spur

of the Tofana (about 12,000 feet high), with a balcony shaped like a

horse-shoe, and with a periphery consisting of numerous jagged peaks.

In the rear of the balcony, and within this rocky spur, the enemy had

excavated numerous caverns in which machine-guns and light artillery

pieces, handled by isolated but able gun-crews, furnished an invisible

and almost impregnable position of defence, giving extraordinary

confidence and encouragement to the small forces occupying them.

“Costeana Valley was accordingly at the mercy of the enemy’s offence

and actually cut in two. From Vervei on, all movements of troops had

to be carried on only at night and with great difficulty. The conquest

of the Castelletto was rendered necessary not only for tactical but

for moral reasons as well, since our troops came to regard it as

absolutely imperative that such an obstacle should be overcome. After

completing my observations and researches regarding the Castelletto

position, I reached the conclusion that the only means of dislodging

the enemy therefrom was to blow it up.

“On November 19 I formally presented my plan to Headquarters, and

about the middle of December I was authorised to attempt it. The

unusual enterprise was a most difficult one, not only on account of

its magnitude, but also on account of the particularly unfavourable

conditions of the winter season. Having prepared the necessary

material for construction and excavation work, I began, on January 3,

1916, fortifying the position (entirely unprotected at the time) from

which we would have to work, and completing the construction of the

necessary buildings.

“Second Lieutenant Malvezzi, in his report on the subject, describes

concisely and modestly the development of the work. The accomplishment

of the enterprise, considered by many as chimerical, is due not only

to the technical ability of Lt. Malvezzi, and Lt. Tissi, his

assistant, but to their special military qualifications as well; also

to the courage and goodwill of the Alpini who, in a very short time,

became a _personnel_ of able miners and clever mechanics.

“The vicissitudes during more than six months’ work, at a distance of

only a few metres from the enemy, and under an incessant artillery

fire and shelling by _bombardas_, could well form the subject for a

book devoted to the study of character. Although fully aware of the

attendant dangers, including those of falling rocks due to the

counter-mining of the enemy, the Alpini of the Castelletto, during the

period of more than six months, gave proofs of brilliant valour and

unflinching perseverance. They were calm at all times, and moved only

by the spirit of duty.

“In transmitting to Your Excellency the enclosed copy of the report

compiled exclusively by Lt. Malvezzi (Lt. Tissi is at present lying

wounded in the hospital), I desire to recommend to you these two

officers (both as excellent engineers and brave soldiers), as well as

the Alpini who were co-operating with them. Without any exaggeration,

I consider their achievement as absolutely marvellous, both on account

of the great technical difficulties surmounted and the military

results obtained. The Austrian officers taken prisoner unanimously

confirm the fact that only by springing a mine could the Italians have

taken this position so important to the enemy.”

* * * * *

Lt. Malvezzi’s appended report launched at once into the “how” of the

titanic task which was set for him.

“On January 3, 1916,” he writes, “work was begun on the approach to

Castelletto, on the Tofana di Roches slope, levelling the soil and

enabling the construction of lodging quarters for officers and troops.

This work required the cutting of 660 cubic metres of rock. Next the

construction of quarters, and the concealing them was quickly

accomplished. Finally, there was garrisoned at this post the

Castelletto Detachment, commonly called the ‘T.K.,’ consisting of the

necessary _personnel_ for labour and the defence of the position.

“Our first work was to examine and disclose the enemy lines of

communication about the Castelletto and Tofana sides, and to gain full

knowledge of their position in detail. In order to accomplish this,

observation points were established which allowed us to carry out such

investigation and to make topographical sketches of the zone. Being as

we were always in the proximity of the enemy, this was a long and

fatiguing work. After a month, however, we succeeded in constructing a

series of positions at short distances from those of the enemy (from

50 to 150 metres). These were provided with cables and rope ladders to

enable us the more rapidly and easily to study (from all possible

points of vantage) the enemy’s positions and the development of his

works.

“The topographic work was begun by taking as a plan metric base

measurement 116 metres of ground on a four-triangle table, which

method enabled making all other drawings based on it. By basing our

findings on this table, we were able to draw up a series of points of

the enemy’s positions. Using the method of successive intersections,

we thus obtained all points of interest to us, as regards direction,

distance and height.

“In addition to this work, executed with the greatest care and

accuracy, we made two independent drawings of the enemy’s positions by

simpler but less exact methods. The first was made with a topographic

compass and Abney level; the other with a Monticole field-square. By

these means we obtained excellent checks on the base system, and so

grounded our work entirely on the trigonometric table and on the

drawings by intersections.

“From the middle of February to the end of March the tools used for

piercing consisted only of mallets and chisels. Our progress was

necessarily slow, yet it was sufficient in this time to give us,

besides 14 metres of tunnel, room for installing the perforating

machinery. At the end of March, notwithstanding heavy snowstorms, the

machinery--some pieces of it weighed as much as 500 and 600 kilos--for

beginning work was installed. This was all brought up by hand, and

without incident.

“The mechanical work was begun on April 2. We utilised two plant as

follows:

“(1) A complete group of benzo-compressors, consisting of a 30-40

horse-power kerosene motor adjusted to a Sullivan compressor by means

of a belt. This machinery was installed, on a solid base of cement, at

the beginning of the tunnel, in a 5 × 8 metre space dug out in the

side of the mountain for that purpose.

“(2) An Ingersoll compressor mounted on a four-wheel truck.

“Both machines were of American manufacture, and gave complete

satisfaction at all times. Each compressed the air to a density of

about seven atmospheres, injecting it into an air-chamber, whence, by

means of a rigid tube, ending in one of flexible rubber, it was

conveyed to the respective drills.

“Four squads worked at a time, each one consisting of a foreman and

from 25 to 30 miners. Each squad worked six hours without

interruption. This shift, apparently light, was found, on the

contrary, to be very heavy, owing principally to the development of

nitric gases which poisoned the air, and to the dust caused by the

drills.

“At first the only explosive used was military gelatine; later,

dynamite-gelatine. The system of over-charging the holes was always

adopted, in order to reduce the _débris_ to minute particles, easier

to be transported and unloaded. The work was carried on in sections,

varying from 1·80 by 1·80 metres to 2 by 2. The flat stretches of the

tunnel were laid with Decauville rails. All material was carried out

in cars and dumped into a hopper discharging into a large pipe. (The

dump was accumulated at a point beyond the observation of the

Austrians.) The average rate of progress was 5·10 metres per day.”

It may be well to explain here that it was not possible to begin

tunnelling on the same level at which the mine was to be exploded, but

considerably more than 150 feet below that level. The tunnel, had,

therefore, to be driven on a steep gradient. Another point which the

report does not make clear should be borne in mind, viz., that the

tunnel divided in the heart of the Castelletto, the main bore being

driven on to where the mine was to be exploded, while a smaller

branch--referred to below as the “Loop-holed Tunnel”--was run up to a

point where favourable exit could be obtained for charging into and

occupying the crater of the exploded mine. In all 507 metres of tunnel

had to be driven, involving the excavation of 2,200 cubic metres of

rock. The details of this work are given in the report as follows:

(A) Chamber for Sullivan Compressor: Dimensions: 5 × 8 metres; average

height 2·20 metres.

(B) First part of gallery to second dump of material. Length 72

metres; inclination 38·70 per cent.; elevation gained 25·90 metres.

(C) Second dump of material, established in order to free space for

further work and reduce the length of transportation.

(D) Ingersoll Group chamber. Dimensions: 4 × 6·50 metres; average

height 2 metres.

(E) Cut from the gallery of the second dump of material to the

beginning of the ascent to the mining chamber. Length 136 metres;

inclination 4·70 per cent.; elevation gained 6·40 metres.

(F) Ascent to mining chamber. Length 22 metres; inclination 36·30 per

cent.; elevation gained 10·75 metres. (This ascent, in order to

facilitate tamping, was worked by dividing it into three sections of 1

× 1·60 metres, at nearly right angles.)

(G) Mining chamber. Dimensions: 5 × 5·50 metres; average height 2·30

metres.

(H) Loop-holed tunnel. Length 162 metres; inclination 60 per cent.;

elevation gained 83·50 metres in this tunnel itself, or a total of

168·50 from the second dump. This tunnel (the one through which the

men were to pass for the attack after the explosion of the mine) had

to be strictly confined to the rocky stratum between the Tofana and

the Castelletto; its planimetry appears (see map), therefore, rather

uneven due to the constant elevation of the rock.

(I) Line of communication--partly in a natural cavern--measuring about

250 metres in length and giving access from the lodging quarters to

the works.

(J) Tunnel dug out to the extreme south end of the Castelletto, 30

metres long, with two portholes (each 4 metres wide) for two Depfort

guns, with closed cavern for the guns and ammunition.

“It was originally intended to divide the explosive charge between two

chambers, each having a mining line of resistance of 20 metres, with a

16-ton explosive charge of 92 per cent. gelatine. However, owing to

the countermining work carried on by the enemy--we were only a few

metres from one of his positions during the charging of the mine

chamber--we were obliged to confine the entire charge to a single

chamber.

“The enemy meanwhile, with a view to avoiding the effects of our mine

beneath the peaks of the Castelletto, had transferred most of his

shelters to the side of the Tofana and the Selletta. This necessitated

a considerable alteration in the location of the mine as originally

planned, in order that it should act against the enemy shelters on

both the Castelletto and Tofana flanks.

[Illustration: PLAN OF THE CASTELLETTO MINING OPERATION.

The worm-like tunnel on the left had to be driven in this way in

order to avoid fissures in the rock which would have revealed

what was going on. It was this tunnel through which the Alpini

were to pass to occupy the crater after the explosion of the

mine, but this plan was defeated through the presence of gas

from detonated Austrian asphyxiating bombs.]

“The charge was computed on a basis of minimum resistance of 20

metres, taking into consideration the nature of the rock (which was

fissured) and the existence of numerous splits and caverns. The

co-efficient of overcharge was, therefore, rather high. In order to

obtain the maximum effect under these conditions, only 92 per cent.

explosive nitro-glycerine was used. The total charge was 35 tons.

“The method of priming adopted was suggested by Lieut.-Col. Tatoli, of

the Engineers Corps. This consisted of five priming groups, each of

three friction tubes. One of the groups ran along the central axis of

the chamber, while the other four, parallel with the first, were

disposed symmetrically facing the four corners of the chamber. Each

tube (1-1/4 inches inside diameter by 4·50 metres in length) was

alternately charged with gelatine and gun-cotton and pierced by picric

acid detonating fuse, ending in a gun-cotton cartridge with electric

percussion cap. In the very centre of the charge there were inserted

two cases of gun-cotton, with electric percussion cap and detonating

fuse, with a view to securing a second springing of the mine to follow

the first.

“We thus had in all seventeen electric circuits divided into three

groups, each formed by the circuits of five tubes, connected with the

five groups of friction tubes. Two of these electric groups were

composed of six circuits each, by adding the two circuits of the

above-mentioned cases containing the gun-cotton. Each of these

electric groups ended with a Cantone exploder, placed at about 4·50

metres distance from the mine-chamber.

“The tamping was effected with cement and with sandbags, with heavy

wooden beams between the latter. It was made more effective by

dividing into sections at right angles to each other. The theoretical

length of the tamping was 25 metres.

“The charging of the mine chamber began July 3, 1916, at 5 p.m., and

was completed at 3 p.m. of July 9 this work including tamping,

priming, and laying of electric circuits. The final connections

between the latter and the exploders, by means of wires suspended in

the air, were made on July 10. The mine was sprung on July 11 at 3.30

p.m., and responded fully to our calculations and expectations.

“(Signed) L. MALVEZZI,

2nd Lieut. 7th Regiment Alpini.”

* * * * *

A week of unspeakable weather went by--an interval the days of which I

spent among the “Cave-men” of the Carso, and the nights of which were

largely devoted to puzzling through the mysteries of the Castelletto

report with the aid of my Italian dictionary--and then the unexpected

miracle happened. Rain and snow ceased, the sky cleared, and a spell

of sparkling days succeeded the interminable months of storm and

lowering clouds. From the high Alps came word that the grip of the

frost had paralysed the avalanches for the moment, and that rapid

progress was being made in opening up the roads for traffic.

“Now is your chance to see the Castelletto,” they told me at

headquarters. “If you start at once you ought to be able to get

through without much trouble; and, if the weather holds good, you may

even be able to get back without long delay, though on that score

you’ll have to take your chances. Doubtless they will be able to get

you out in some way whatever happens.”

And so it chanced that on a diamond-bright morning in early January I

found myself, after a couple of days of strenuous motoring, speeding

in a military car past the old custom-house and up into the heart of

that most weirdly grand of all Alpine regions, the Dolomites. Already

we were well over into what had once been Austrian territory, and the

splintered pinnacles which notched the skyline ahead of us were, as my

escorting officer explained, held in part by both the Italians and

the enemy. As we coasted down into Cortina di Ampezzo--which in its

swarming tourist hotels of motley design rivals St. Moritz or

Chamonix--Capt. P---- pointed to where a clean-lined wall of

snow-capped yellow rock reared itself against the deep purple of the

western sky.

“That high mountain ridge is the Tofana _massif_,” he said, “and that

partly isolated mass of lighter-coloured rock (crowned with towers

like a mediæval stronghold) at its further end is what is left of the

famous Castelletto. It is twenty kilometres or more away, but you can

see even from here how it dominated the valley and road, the latter

the much-pictured Dolomite road, which is also a route of great

military importance.

“Now look at the end of the Castelletto toward the wall of the Tofana.

Do you see where it seems to have been sliced off smoothly at an angle

of about forty-five degrees? Well, that is the part they blew off last

July. Up to then that end, like the other, was crowned with a lofty

spire. That spire, the base from which it sprung, the Austrian

barracks and munition depôts, together with the men stationed

there--all were blown up and destroyed in the explosion.

“Take a good look at it while you have a chance, for the skyline view

is better from a distance than from close at hand, where we shall go

this afternoon if the way is open. To see the effect of the explosion

at its best,” he added, “one should look at it from the Austrian

lines, as it was the blowing out of the other side of the mountain

which undermined and let down the top. If you come back here in the

spring doubtless we will be in occupation of a number of interesting

observation points over there.”

Viewed even from a distance of a dozen miles or more the alteration

wrought in the skyline by the explosion was not difficult to imagine.

It was, indeed, literally true--what I had never been fully able to

make myself believe until that moment--that a mountain peak had been

blown off--hundreds of feet of it, and thousands of tons. My eyes

remained focussed in awed fascination on the unnaturally even profile

of the wound until our snorting car skidded round a bend of the frozen

road and the thick-growing pine forest shut it from sight.

It was not until, after ten miles of precarious climbing and clawing

up the ice-paved, snow-walled road, our car brought up in the midst of

a neat little group of Alpine buildings nestling in the protection of

the last of the timber, that Capt. P---- revealed the surprise that

had been prepared for me.

“Our host here,” he said, “will be Colonel X----, who conceived and

directed the Castelletto project, and at dinner to-night you will

meet, and can talk as long as you like, with Lieutenant Malvezzi, who

did the work. He is still quartered here, and will be glad to tell you

all that he can about Alpine military engineering. We have already

sent him word that you came to Italy expressly to see him.”

After a hasty lunch Capt. P---- and I, accompanied by an officer of

Alpini from the camp, started for the Castelletto. Our powerful

military car, which, in spite of the fact that it had non-skid tyres,

had been giving a good deal of trouble on the ice, was left behind,

and a smaller but heavily-engined machine, with sharp spikes clamped

over the rims to grip the glassy surface of the road, was taken for

the few miles of the latter which were still open. Abandoning this in

a snow-bank at a little advanced camp well up under the towering wall

of the Tofana, we took our alpenstocks and started on the 2,000-foot

climb up to the base of the Castelletto.

The hard-packed snow on the thirty to forty degree slope must have

averaged from ten to twenty feet deep all the way, while, for a

half-mile or so midway, it was humped up in crumpled fold where, a

fortnight before, one of the largest and most terrible slides ever

known in the Alps had plunged down on its sinister mission to the

bottom of the valley. The full story of that avalanche will hardly be

told until after the war.

Slightly softened by the brilliant sun, the snow gave good footing;

but even so it was a stiff pull to the little ice and rock-begirt

barracks at the base of the cliff, and I gained some idea of the

titanic labour involved in getting guns, munitions, machinery, food,

and thirty-five tons of high explosive up there, all by hand, in every

sort of weather, and much of it (to avoid enemy observation and fire)

at night.

Midwinter was not, of course, the time to see anything of the real

effects of the great explosion, for the huge crater torn by the latter

was drifted full of snow, and snow was also responsible for the

complete obliteration of the countless thousands of tons of _débris_

that had been precipitated down the mountain side. A dizzy climb up

the ladder-like stairway, and a crawling clamber through a hundred

yards of the winding tunnel from the rock chambers which had housed

the compressors, revealed about all that was visible at the time of

the preparations and consequences of the mighty work; but a peep from

the observation port of a certain cunningly concealed gun-cavern

discovered a panorama which gave illuminative point to the concluding

words of the artillery officer who, pointing with the shod handle of

an ice-pick, explained the situation to me from that vantage.

“So you see,” he had said, “that the Castelletto in the enemy’s hands

was a stone wall which effectually barred our further progress; while

in our hands it becomes a lever which--whenever we really need to take

them--will pry open for us positions of vital importance. We simply

_had_ to have it; and so we took it in the one way it could be taken.

* * * * *

“Save for his Alpini uniform Lieutenant Malvezzi, when I met him at

dinner that evening, might well have passed for the typical musician

of drama or romance. His skin and hair and eyes were dark, and his

long nervous fingers flitted over the paper on which he sketched

various phases of the Castelletto work very much as those of a pianist

flit above his ivory keys. The dreamy, far-away look in his eyes was

also suggestive of the musician, but that I had long come to recognise

as equally characteristic of all great engineers, the men whose

tangible achievements are only the fruition of days and nights of

dreaming.

“Where shall I begin the story?” he had asked as the diners in the

regimental mess began to resolve into little knots of threes and fours

over coffee and cigars; and I had suggested that he take it up where

his report left off. “That stopped just as things began to happen,” I

said. “Now tell what _did_ happen.”

The Tenente laughed a laugh suggestive of rueful reminiscence, and a

smile ran round among those of the officers who had heard and

understood my words. “So far as I am concerned,” he replied, “that

covers about five minutes of activity--five minutes for which we had

been preparing for six months. You understand that we had constructed

a branch tunnel through which our men were to rush and occupy the

crater as soon after the explosion as possible.

“_Ecco._ The men were all massed ready on and under the terrace, and

nothing remained but the making of the connection firing the mine. I

took one long look around and then threw over the electric switch

closing the circuit. Every one seemed to be holding his breath as he

waited. One, two, three seconds passed in a silence so intense that I

heard the sharp ‘ping’ of the water dripping from the roof of the

chamber and striking the pool it had formed below.

“Then, before any other sound was audible, the whole mountain gave a

quick convulsive jerk, strong enough to throw some of the men off

their feet. A heavy grinding rumble in the earth came with a shivering

that followed the jerk, but the real roar of the explosion (from the

outside) was not audible for a second or two later. Only those

watching from a distance of several kilometres saw the right-hand

pinnacle of the Castelletto give a sudden heave, and then sink out of

sight in a cloud of dust and smoke.

“In addition to the honour of firing the mine that of leading my men

into the crater had also been reserved for me, and as soon as I heard

the roar of the explosion I gave the order for them to follow me up

into the tunnel. Well----” he paused and ran his laughing eyes around

the grinning circle of his fellow officers, “that is about as far as

my evidence is good for anything. As I went clambering up the slippery

steps of the tunnel an almost solid wall of choking fumes struck me in

the face, and I--and all of my men except those near or outside of the

portal--dropped coughing in my tracks.”

“Had the mine blown back through the tamping?” I asked.

“Not exactly,” he replied, his rueful smile becoming almost sheepish,

as of one who had allowed himself to become the victim of a prank.

“The Austrians had a big store of asphyxiating bombs on hand to use

against us, and these, exploded by our mine, vented their spite on

friend and foe alike. We were not able to occupy the crater for

twenty-four hours.

“I am glad to say that I spent what would otherwise have been an

intolerably anxious interval unconscious in the hospital. By the time

I had been revived a friendly breeze had thinned the gas sufficiently

to allow our Alpini to move into the crater and reap--in spite

of the delay--every advantage we had at any time counted

upon from the operation. Our most cherished capture was the

‘perforator’--practically intact--with which the Austrians were

driving an almost completed counter-mine directly under us.”

“The nervous tension must have been rather strong toward the end,

wasn’t it?” I asked; “especially when you knew the enemy had at last

got your work definitely located and was rushing his counter-mine?”

The smile of whimsical ruefulness died out of the dark sensitive face,

leaving behind it lines I had not noticed before--lines that only

come on young faces after weeks or months of incessant anxiety. The

backward cast shadows of a time of terrible memory were lurking behind

his eyes as he replied:

“For seven days and nights before the mine was sprung neither I nor

the officers working with me slept or even rested from work.”

That was all he said; but I saw the eyes--brimming with ready

sympathy--of his fellow officers turn to where he sat, and knew the

time for light questionings was past. Not until that moment did a full

appreciation of the travail involved in the blowing up of the

Castelletto sink home to me, and I nodded fervent assent to the words

of the English-educated Captain of Alpini next me when he observed

that “Malvezzi’s little ‘Order of Savoie’ was jolly well earned, eh?”
