the largest number which Eastern historians state to have been slaughtered in any of the numerous conflicts between Asiatic rulers, make me regard the engagement in which they fell as one of paramount importance to mankind. But, besides battles of this kind, there are many of great consequence, and attended with circumstances which powerfully excite our feelings and rivet our attention, and yet which appear to me of mere secondary rank, inasmuch as either their effects were limited in area, or they themselves merely confirmed some great tendency or bias which an earlier battle had originated. For example, the encounters between the Greeks and Persians, which followed Marathon, seem to me not to have been phenomena of primary impulse. Greek superiority had been already asserted, Asiatic ambition had already been checked, before Salamis and Platæa confirmed the superiority of European free states over Oriental despotism. So Ægospotamos, which finally crushed the maritime power of Athens, seems to me inferior in interest to the defeat before Syracuse, where Athens received her first fatal check, and after which she only struggled to retard her downfall. I think similarly of Zama with respect to Carthage, as compared with the Metaurus; and, on the same principle, the subsequent great battles of the Revolutionary war appear to me inferior in their importance to Valmy, which first determined the military character and career of the French Revolution.
I am aware that a little activity of imagination and a slight exercise of metaphysical ingenuity may amuse us by showing how the chain of circumstances is so linked together, that the smallest skirmish, or the slightest occurrence of any kind, that ever occurred, may be said to have been essential in its actual termination to the whole order of subsequent events. But when I speak of causes and effects, I speak of the obvious and important agency of one feet upon another, and not of remote and fancifully
