we must next remark that the advance to the Danube was the more meritorious, and gives the higher lustre to Marlborough’s fame as a general, from the fact that it was an attempt involving a great military hazard, and that yet that attempt had to be made in the face of political difficulties of peculiar severity.

      In other words, Marlborough was handicapped in a fashion which lends his success a character peculiar to itself, and worthy of an especial place in history.

      This handicap may be stated by a consideration of three points which cover its whole character.

      The first of these points concerns the physical conditions of the move; the other two are peculiar to the political differences of the allies.

      It was in the nature of the move that a high hazard was involved in it. The general had calculated, as a general always must, the psychology of his opponent. If he were wrong in his calculation, the advance on the Danube could but lead to disaster. It was for him to judge whether the French were so nervous about the centre of their position upon the Rhine as to make them cling to it to the last moment, and tend to believe that it was either along the Moselle or (when he had left that behind) in Alsace that he intended to attack. In other words, it was for him to make the French a little too late in changing their dispositions, a little too late in discovering what his real plan was, and therefore a little too late in massing larger reinforcements upon the Upper Danube, where he designed to be before them.

      Marlborough guessed his opponent’s psychology rightly; the French marshals hesitated just too long, their necessity of communicating with Louis at Versailles further delayed them, and the great hazard which he risked was therefore risked with judgment. But a hazard it remained until almost the last days of its fruition. The march must be rapid; it involved a thousand details, each requiring his supervision and his exact calculation, his knowledge of what could be expected of his troops, and his survey of daily supply.

      There was another element of hazard.

      Arrived at his destination upon the plains of the Danube, Marlborough would be very far from any good base of supply.

      The country lying in the triangle between the Upper Danube and the Middle Rhine, especially that part of it which is within striking distance of the Danube, is mountainous and ill provided with those large towns, that mobilisable wealth, and those stores of vehicles, munitions, food, and remounts which are the indispensable sustenance of an army.

      The industry of modern Germany has largely transformed this area, but even to-day it is one in which good depots would be rare to find. Two hundred years ago, the tangle of hills was far more deserted and far worse provided.

      By the time Marlborough should have effected his junction with his ally in the upper valley of the Danube only two bases of supply would be within any useful distance of the new and distant place to which he was transferring his great force.

      The most important of these, his chief base, and his only principal store of munitions and every other requisite, was Nuremberg; and that town was a good week from the plains upon the bank of the Danube where he proposed to act. As an advanced base nearer to the river, he could only count upon the lesser town of Nordlingen.

      Therefore, even if he should successfully reach the field of action which he proposed, cross the hills between the two river basins without loss or delay, and be ready to act as he hoped upon the banks of the Danube before the end of June, his stay could not be indefinitely prolonged there, and his every movement would be undertaken under the anxiety which must ever haunt a commander dependent on an insufficient or too distant base of supply. This anxiety, be it noted, would rapidly increase with every march he might have to take southward of the Danube, and with every day’s advance into Bavaria itself, if, as he hoped, the possibility of such an advance should crown his efforts.

      We have seen that the great hazard which Marlborough risked made it necessary, as he advanced southward up the Rhine during the first half of his march, to keep Villeroy and Tallard doubtful as to whether his objective was the Moselle or, later, Alsace; and while they were still in suspense, abruptly to leave the valley of the Rhine and make for the crossing of the hills towards the Danube. So long as the French marshals remained uncertain of his intentions, they would not dare to detach any very large body of troops from the Rhine valley to the Elector’s aid: under the conditions of the time, the clever handling of movement and information might create a gap of a week at least between his first divergence from the Rhine and his enemy’s full appreciation that he was heading for the south-east.

      He so concealed his information and so ordered his baffling movements as to achieve that end.

      So much for the general hazard which would have applied to any commander undertaking such an advance.

      But, as I have said, there were two other points peculiar to Marlborough’s political position.

      The first was, that he was not wholly free to act, as, for instance, Cæsar in Gaul was free, or Napoleon after 1799. He must perpetually arrange matters, in the first stages with the Dutch commissioner, later with the imperial general, Prince Louis of Baden, who was his equal in command. He must persuade and even trick certain of his allies in all the first steps of the great business; he must accommodate himself to others throughout the whole of it.

      Secondly, the direction in which he took himself separated him from the possibility of rapidly communicating his designs, his necessities, his chances, or his perils to what may be called his moral base. This moral base, the seat both of his own Government and of the Dutch (his principal concern), lay, of course, near the North Sea, and under the immediate supervision of England and the Hague. This is a point which the modern reader may be inclined to ridicule until he remembers under what conditions the shortest message, let alone detailed plans and the execution of considerable orders, could alone be performed two hundred years ago. By a few bad roads, across a veritable dissected map of little independent or quasi-independent polities, each with its own frontier and prejudices and independent government, the messenger (often a single messenger) must pass through a space of time equivalent to the passage of a continent to-day, and through risks and difficulties such as would to-day be wholly eliminated by the telegraph. The messenger was further encumbered by every sort of change from town to town, in local opinion, and the opportunities for aid.

      More than this, in marching to the Danube, Marlborough was putting between himself and that upon which he morally, and most of all upon which he physically, relied, a barrier of difficult mountain land.

      Having mentioned this barrier, it is the place for me to describe the physical conditions of that piece of strategy, and I will beg the reader to pay particular attention to the accompanying map, and to read what follows closely in connection with it.

      In all war, strategy considers routes, and routes are determined by obstacles.

      Had the world one flat and uniform surface, the main problems of strategy would not exist.

      The surface of the world is diversified by certain features—rivers, chains of hills, deserts, marshes, seas, etc.—the passage across which presents difficulties peculiar to an army, and it is essential to the reading of military history to appreciate these difficulties; for the degrees of impediment which natural features present to thousands upon the march are utterly different from those which they present to individuals or to civilian parties in time of peace. Since it is to difficulties of this latter sort that we are most accustomed by our experience, the student of a campaign will often ask himself (if he is new to his subject) why such and such an apparently insignificant stream or narrow river, such and such a range of hills over which he has walked on some holiday without the least embarrassment, have been treated by the great captains as obstacles of the first moment.

      The reason that obstacles of any sort present the difficulty they do to an army, and present it in the high degree which military history discovers, is twofold.
