On my first walk around the city, yesterday morning, I passed the Augustus Platz--a broad green lawn on which front the university and several other public buildings. A chain of beautiful promenades encircles the city on the site of its old fortifications. Following their course through walks shaded by large trees and bordered with flowering shrubs, I passed a small but chaste monument to Sebastian Bach, the composer, which was erected almost entirely at the private cost of Mendelssohn, and stands opposite the building in which Bach once directed the choirs. As I was standing beside it a glorious choral swelled by a hundred voices came through the open windows like a tribute to the genius of the great master. Having found my friend, we went together to the Sternwarte, or observatory, which gives a fine view of the country around the city, and in particular the battlefield. The castellan who is stationed there is well acquainted with the localities, and pointed out the position of the hostile armies. It was one of the most bloody and hard-fought battles which history records. The army of Napoleon stretched like a semicircle around the southern and eastern sides of the city, and the plain beyond was occupied by the allies, whose forces met together here. Schwarzenberg, with his Austrians, came from Dresden; Blücher, from Halle, with the Emperor Alexander. Their forces amounted to three hundred thousand, while those of Napoleon ranked at one hundred and ninety-two thousand men. It must have been a terrific scene. Four days raged the battle, and the meeting of half a million of men in deadly conflict was accompanied by the thunder of sixteen hundred cannon. The small rivers which flow through Leipsic were swollen with blood, and the vast plain was strewed with more than fifty thousand dead. It is difficult to conceive of such slaughter while looking at the quiet and tranquil landscape below. It seemed more like a legend of past ages, when ignorance and passion led men to murder and destroy, than an event which the last half century witnessed. For the sake of humanity it is to be hoped that the world will never see such another.
