passage 537 of 539 · BOOK I. ON THE NATURE OF WAR > CHAPTER IX. Plan of War when the Destruction of the Enemy is the Object (18/20)

in brief
He complicates the simple two-pronged attack on Paris by arguing Austria must avoid exposing Italy, and England’s naval advantage forces France to defend Atlantic coasts, diverting troops from the main theater.

But there are two considerations which interfere with the simplicity of this plan.

The Austrians would not lay bare their Italian dominions, they would wish to retain the mastery over events there, in any case, and therefore would not incur the risk of making an attack on the heart of France, by which they would leave Italy only indirectly covered. Looking to the political state of the country, this collateral consideration is not to be treated with contempt; but it would be a decided mistake if the old and oft-tried plan of an attack from Italy, directed against the South of France, was bound up with it, and if on that account the force in Italy was increased to a size not required for mere security against contingencies in the first campaign. Only the number needed for that security should remain in Italy, only that number should be withdrawn from the great undertaking, if we would not be unfaithful to that first maxim, Unity of plan, concentration of force. To think of conquering France by the Rhone, would be like trying to lift a musket by the point of its bayonet; but also as an auxiliary enterprise, an attack on the South of France is to be condemned, for it only raises new forces against us. Whenever an attack is made on distant provinces, interests and activities are roused, which would otherwise have lain dormant. It would only be in case that the forces left for the security of Italy were in excess of the number required, and, therefore, to avoid leaving them unemployed, that there would be any justification for an attack on the South of France from that quarter.

We therefore repeat that the force left in Italy must be kept down as low as circumstances will permit; and it will be quite large enough if it will suffice to prevent the Austrians from losing the whole country in one campaign. Let us suppose that number to be 50,000 men for the purpose of our illustration.

Another consideration deserving attention, is the relation of France in respect to its sea-coast. As England has the upper hand at sea, it follows that France must, on that account, be very susceptible with regard to the whole of her Atlantic coast; and, consequently, must protect it with garrisons of greater or less strength. Now, however weak this coast-defence may be, still the French frontiers are tripled by it; and large drafts, on that account, cannot fail to be withdrawn from the French army on the theatre of war. Twenty or thirty thousand troops disposable to effect a landing, with which the English threaten France, would probably absorb twice or three times the number of French troops; and, further, we must think not only of troops, but also of money, artillery, etc., etc., required for ships and coast batteries. Let us suppose that the English devote 25,000 to this object.

Our plan of war would then consist simply in this:

  1. That in the Netherlands:— 200,000 Prussians, 75,000 Netherlanders, 25,000 English, 50,000 North German Confederation, ————— Total: 350,000 be assembled,

of whom about 50,000 should be set aside to garrison frontier fortresses, and the remaining 300,000 should advance against Paris, and engage the French Army in a decisive battle.

  1. That 200,000 Austrians and 100,000 South German troops should assemble on the Upper Rhine to advance at the same time as the army of the Netherlands, their direction being towards the Upper Seine, and from thence towards the Loire, with a view, likewise, to a great battle. These two attacks would, perhaps, unite in one on the Loire.

By this the chief point is determined. What we have to add is chiefly intended to root out false conceptions, and is as follows:—
