Namur is now the head-quarters of Marshal Blucher, who is in the enjoyment of divers _noms de guerre_, such as "Marshall Vorwärts," "Der alte Teufel." On the high road, about two miles and a half before we reached Namur, we met with a party of Prussian lancers, who were returning from a foraging excursion. They were singing some warlike song or hymn, which was singularly impressive. It brought to my recollection the description of the Rhenish bands in the _Lay of the Last Minstrel_: Who as they move, in rugged verse Songs of Teutonic feuds rehearse. The Prussian cavalry seem to be composed of fine-looking young men, and I admire the genuine military simplicity of their dress, to which might be most aptly applied the words of Xenophon when describing the costume of the younger Cyrus: [Greek: _En tae Persikae stolae ouden ti hubrsmenae_][7] in substituting merely the word [Greek: _Prussikae_] for [Greek: _Persikae_]. One sees in it none of those absurd ornaments and meretricious foppery which give to our cavalry officers the appearance of Astley's men.[8] The situation of Namur is exceedingly picturesque, particularly when viewed from the heights which tower above the town, whereon stood the citadel which was demolished by order of Joseph II, as were the fortifications of all the frontier fortresses. The present Belgian Government however mean to reconstruct them, and Namur in particular, the citadel of which, from the natural strength of its position, is too important a post to be neglected. The town itself is situated on the confluent of the Sambre and Meuse and lies in a valley completely commanded and protected by the citadel. The churches are splendid, and there is an appearance of opulence in the shops. The inhabitants, from its being a frontier town, are of course much alarmed at the approaching contest, for they will probably suffer from both parties. We heard at the inn and in the shops which we visited the same complaints against the Prussians. The country in the environs of this place is exceedingly diversified, and it presents the first mountain scenery we have yet met with. The banks of the Meuse hereabouts present either an abrupt precipice or coteaux covered with vines gently sloping to the water's edge. Namur is distant thirty-four miles from Brussels, and there is water conveyance on the Meuse from here to Liége and Maastricht. MONS, May 14.
