But if this be frequently, or generally, the fortune of military achievements, it is not always so. There are enterprises, military as well as civil, which sometimes check the current of events, give a new turn to human affairs, and transmit their consequences through ages. We see their importance in their results, and call them great, because great things follow. There have been battles which have fixed the fate of nations. These come down to us in history with a solid and permanent interest, not created by a display of glittering armor, the rush of adverse battalions, the sinking and rising of pennons, the flight, the pursuit, and the victory; but by their effect in advancing or retarding human knowledge, in overthrowing or establishing despotism, in extending or destroying human happiness. When the traveller pauses on the plain of Marathon,[4] what are the emotions which most strongly agitate his breast? What is that glorious recollection which thrills through his frame, and suffuses his eyes? Not, I imagine, that Grecian skill and Grecian valor were here most signally displayed; but that Greece herself was saved. It is because to this spot, and to the event which has rendered it immortal, he refers all the succeeding glories of the republic. It is because, if that day had gone otherwise, Greece had perished. It is because he perceives that her philosophers and orators, her poets and painters, her sculptors and architects, her governments and free institutions, point backward to Marathon, and that their future existence seems to have been suspended on the contingency whether the Persian or the Grecian banner should wave victorious in the beams of that day's setting sun. And, as his imagination kindles at the retrospect, he is transported back to the interesting moment; he counts the fearful odds of the contending hosts; his interest for the result overwhelms him; he trembles, as if it were still uncertain, and seems to doubt whether he may consider Socrates and Plato, Demosthenes, Sophocles, and Phidias, as secure yet to himself and to the world.
