The marvellous influence of war songs over the ancient Norsemen is difficult to understand. They were aroused to a high degree of military enthusiasm, almost to madness, by the mere words of certain songs. That it was this influence which frequently drove them onward to great deeds, appears in every chapter of their life history. It was the courage and frenzy aroused by Teutonic war songs that led to the destruction of Rome, and shattered the civilization of southern Europe. That the influence of the war song over the minds and the hearts of men did not terminate with the long ago past, is apparent to every student of modern history. Garibaldi's warlike Hymn of the Italians, the stirring "Marseillaise" of the light-hearted French, the vigorous "Britannia" of the sturdy English, have inspired determination and aroused courage on many a bloody battlefield. How frequently during our own civil war was retreat checked, and the tide of battle turned, by the singing of "We'll Rally round the Flag, Boys," started at the opportune moment by some brave soldier with a vigorous and melodious voice. It has been said that the Portuguese soldiers in Ceylon, at the siege of Colombo, when pressed with misery and the pangs of hunger, during their marches, derived not only consolation but also encouragement from singing stanzas of their national song. It is a singular fact that no great national hymn, and no war song that arouses and cheers, was ever written by a distinguished poet. It would seem that a National Hymn is the sort of material that cannot be made to order. Not one of the best-known songs of our own civil war--in the North or in the South--was written by an eminent poet. Five of the greatest American poets were living during the great conflict, and four of them gave expression to its military ardor, determinate zeal, or pathos, but none of them so sung as to touch the popular heart; that is to say, so as to secure the attention of those who do not read poetry. The same is true of the composers of the national anthems and great martial ballads of nearly every other country. The thunder roar of the "Marseillaise," before which all the other military songs of France are dull and weak, was produced by De l'Isle, who lives in the memory of his countrymen and of the world for this alone. The noble measures of "God Save the King" are not the work of any one of the great British poets, but were probably written by Henry Carey; but this is in dispute, and innumerable Englishmen sing the anthem without even attempting to learn the name of the composer. The Prussian National Anthem was not written by a Goethe, a Schiller, or even a Köner. The name of the writer, Schneckenburger, would not be found in books of reference had he not written "The Watch on the Rhine." The favorite national song of the Italians, known as the "Garibaldian Hymn," is the composition of Mercantini, of whom little is known.
