We all know that as a matter of fact the Revolution was, upon the whole, successful in imposing its view upon Europe. We all know that from that success as from a germ has proceeded, and is still proceeding, modern society. But the nature, the cause and the extent of the military success which alone made this possible, is widely ignored and still more widely misunderstood. No other signal military effort which achieved its object has in history ended in military disaster--yet this was the case with the revolutionary wars. After twenty years of advance, during which the ideas of the Revolution were sown throughout Western civilisation, and had time to take root, the armies of the Revolution stumbled into the vast trap or blunder of the Russian campaign; this was succeeded by the decisive defeat of the democratic armies at Leipsic, and the superb strategy of the campaign of 1814, the brilliant rally of what is called the Hundred Days, only served to emphasise the completeness of the apparent failure. For that masterly campaign was followed by Napoleon’s first abdication, that brilliant rally ended in Waterloo and the ruin of the French army. When we consider the spread of Grecian culture over the East by the parallel military triumph of Alexander, or the conquest of Gaul by the Roman armies under Cæsar, we are met by political phenomena and a political success no more striking than the success of the Revolution. The Revolution did as much by the sword as ever did Alexander or Cæsar, and as surely compelled one of the great transformations of Europe. But the fact that the great story can be read to a conclusion of defeat disturbs the mind of the student. Again, that element fatal to all accurate study of military history, the imputation of civilian virtues and motives, enters the mind of the reader with fatal facility when he studies the revolutionary wars. He is tempted to ascribe to the enthusiasm of the troops, nay, to the political movement itself, a sort of miraculous power. He is apt to use with regard to the revolutionary victories the word “inevitable,” which, if ever it applies to the reasoned, willing and conscious action of men, certainly applies least of all to men when they act as soldiers. There are three points which we must carefully bear in mind when we consider the military history of the Revolution. First, that it succeeded: the Revolution, regarded as the political motive of its armies, won. Secondly, that it succeeded through those military aptitudes and conditions which happened to accompany, but by no means necessarily accompanied, the strong convictions and the civic enthusiasm of the time. Thirdly, that the element of chance, which every wise and prudent reasoner will very largely admit into all military affairs, worked in favour of the Revolution in the critical moments of the early wars.
