On the 2nd of September Verdun was entered by the Prussians, and a
little outside the gates of the town, near a village bearing the name of
Regret, the allied camp was fixed. Rather more than a week later, on the
11th, the Allies marched against the line of the Argonne.
The reader will remember that this moment, with the loss of the frontier
fortresses Longwy and Verdun, and the evidence of demoralisation which
that afforded, was also the moment of the September massacres and of the
horrors in Paris. Dumouriez and the mixed French force which he
commanded had been ordered by the Ministers of War to hold the line of
the Argonne against which the Allies were marching. And here it is well
to explain what was meant in a military sense by this word “line.”
The Argonne is a long, nearly straight range of hills running from the
south northward, a good deal to the west of north.
Their soil is clay, and though the height of the hills is only three
hundred feet above the plain, their escarpment or steep side is towards
the east, whence an invasion may be expected. They are densely wooded,
from five to eight miles broad, the supply of water in them is bad, in
many parts undrinkable; habitation with its provision for armies and
roads extremely rare. It is necessary to insist upon all these details
because the greater part of civilian readers find it difficult to
understand how formidable an obstacle so comparatively unimportant a
feature in the landscape may be to an army upon the march. It was quite
impossible for the guns, the wagons, and therefore the food and the
ammunition of the invading army, to pass through the forest over the
drenched clay land of that wet autumn save where proper roads existed.
These were only to be found wherever a sort of natural pass negotiated
the range.
Three of these passes alone existed, and to this day there is very
little choice in the crossing of these hills. The accompanying sketch
will explain their disposition. Through the southernmost went the great
high road from the frontier and Verdun to Paris. At the middle one
(which is called the Gap of Grandpré) Dumouriez was waiting with his
incongruous army. The third and northern one was also held, but less
strongly. The obvious march for an unimpeded invader would have been
from Verdun along the high road, through the southern pass at “Les
Islettes,” and so to Chalôns and on to Paris. But Dumouriez, marching
down rapidly from the north, had set an advanced guard to hold that pass
and was lying himself with the mass of the army on the pass to the north
of it at Grandpré. Against Grandpré the Prussians marched, and meanwhile
the Austrians were attacking the further pass to the north. Both were
forced. Dumouriez fell back southward to St. Menehould. Meanwhile
Kellermann was coming up from Metz to join him, and all the while the
main pass at “Les Islettes,” through which the great road to Paris went,
continued to be held by the French.

Argonne and the Cannonade at Valmy, September 1792.]
The Prussians and the Austrians joined forces in the plain known as the
Champagne Pouilleuse, which lies westward of Argonne. It will be seen
that as they marched south along this plain to meet Dumouriez and to
defeat him, their position was a peculiar one: they were nearer the
enemy’s capital than the enemy’s army was, and yet they had to fight
with their backs to that capital, and their enemy the French had to
fight with their faces towards it. Moreover, it must be remarked that
the communications of the Allied Army were now of a twisted, roundabout
sort, which made the conveyance of provisions and ammunition slow and
difficult--but they counted upon an immediate destruction of Dumouriez’
force and after that a rapid march on the capital.
On September 19 Kellermann came up from the south and joined hands with
Dumouriez near St. Menehould, and on the morning of the 20th his force
occupied a roll of land on which there was a windmill and immediately
behind which was the village of Valmy; from this village the ensuing
action was to take its name. It must here be insisted upon that both
armies had been subjected to the very worst weather for more than a
fortnight, but of the two the Prussian force had suffered from this
accident much more severely than the French. Dysentery had already
broken out, and the length and tortuousness of their communications were
greatly emphasised by the condition of the roads.
On the morning of that day, the 20th of September, a mist impeded all
decisive movements. There was an encounter, half accidental, between an
advanced French battery and the enemy’s guns, but it was not until
mid-morning that the weather lifted enough to show each force its
opponent. Then there took place an action, or rather a cannonade, the
result of which is more difficult to explain, perhaps, than any other
considerable action of the revolutionary wars. For some hours the
Prussian artillery, later reinforced by the Austrian, cannonaded the
French position, having for its central mark the windmill of Valmy,
round which the French forces were grouped. At one moment this cannonade
took effect upon the limbers and ammunition wagons of the French; there
was an explosion which all eye-witnesses have remembered as the chief
feature of the firing, and which certainly threw into confusion for some
moments the ill-assorted troops under Kellermann’s command. At what hour
this took place the witnesses who have left us accounts differ to an
extraordinary extent. Some will have it at noon, others towards the
middle of the afternoon--so difficult is it to have any accurate account
of what happens in the heat of an action. At any rate, if not
coincidently with this success, at some moment not far removed from it,
the Prussian charge was ordered, and it is here that the difficulties of
the historian chiefly appear. That charge was never carried home;
whether, as some believe, because it was discovered, after it was
ordered, to be impossible in the face of the accuracy and intensity of
the French fire, or whether, as is more probably the case, because the
drenched soil compelled the commanders to abandon the movement after it
had begun--whatever the cause may have been, the Prussian force, though
admirably disciplined and led, and though advancing in the most exact
order, failed to carry out its original purpose. It halted halfway up
the slope, and the action remained a mere cannonade without immediate
result apparent upon either side.
Nevertheless that result ultimately turned out to be very great, and if
we consider its place in history, quite as important as might have been
the result of a decisive action. In the first place, the one day’s delay
which it involved was just more than the calculations of the Allies,
with their long impeded line of communications, had allowed for. In the
next place, a singular increase in determination and moral force was
infused into the disheartened and ill-matched troops of the French
commanders by this piece of resistance.
We must remember that the French force upon the whole expected and
discounted a defeat, the private soldier especially had no confidence in
the result; and to find that at the first action which had been so long
threatened and had now at last come, he could stand up to the enemy,
produced upon him an exaggerated effect which it would never have had
under other circumstances.
Finally, we must recollect that whatever causes had forbidden the
Prussian charge forbade on the next day a general advance against the
French position. And all the time the sickness in the Prussian camp was
rapidly increasing. Even that short check of twenty-four hours made a
considerable difference. A further delay of but yet another day, during
which the Allied Army could not decide whether to attack at once or to
stand as they were, very greatly increased the list of inefficients from
illness.
For a whole week of increasing anxiety and increasing inefficiency the
Allied Army hung thus, impotent, though they were between the French
forces and the capital. Dumouriez ably entertained this hesitation, with
all its accumulating dangers for the enemy, by prolonged negotiations,
until upon the 30th of September the Prussian and Austrian organisation
could stand the strain no longer, and its commanders determined upon
retreat. It was the genius of Danton, as we now know, that chiefly
organised the withdrawal of what might still have been a dangerous
invading force. It is principally due to him that no unwise Jingoism was
permitted to claim a trial of strength with the invader, that he was
allowed to retire with all his guns, his colours and his train. The
retreat was lengthy and unmolested, though watched by the French forces
that discreetly shepherded it but were kept tightly in hand from Paris.
It was more than three weeks later when the Allied Army, upon which
Europe and the French monarchy had counted for an immediate settlement
of the Revolution, re-crossed the frontier, and in this doubtful and
perhaps inexplicable fashion the first campaign of the European Powers
against the Revolution utterly failed.
