In August, 1813, the tempest of war broke loose on every side, and all Europe prepared for a decisive struggle. About this time, the whole of Northern Germany was visited for some weeks, as was the case on the defeat of Varus in the Teutoburg forest, with heavy rains and violent storms. The elements seemed to combine, as in Russia, their efforts with those of man against Napoleon. There his soldiers fell victims to frost and snow, here they sank into the boggy soil and were carried away by the swollen rivers. In the midst of the uproar of the elements, bloody engagements continually took place, in which the bayonet and the butt-end of the firelock were almost alone used, the muskets being rendered unserviceable by the wet. The first engagement of importance was that of the 21st of August between Wallmoden and Davoust at Vellahn. A few days afterward, Theodore Korner, the youthful poet and hero, fell in a skirmish between the French and Wallmoden's outpost at Gadebusch.--Oudinot advanced close upon Berlin, which was protected by the crown prince of Sweden. A murderous conflict took place, on the 23d of August, at Gross-Beeren between the Prussian division under General von Bulow and the French. The Swedes, a troop of horse artillery alone excepted, were not brought into action, and the Prussians, unaided, repulsed the greatly superior forces of the French. The almost untrained peasantry comprising the _Landwehr_ of the Mark and of Pomerania rushed upon the enemy, and, unhabituated to the use of the bayonet and firelock, beat down entire battalions of the French with the butt-end of their muskets. After a frightful massacre, the French were utterly routed and fled in wild disorder, but the gallant Prussians vainly expected the Swedes to aid in the pursuit. The crown prince, partly from a desire to spare his troops and partly from a feeling of shame--he was also a Frenchman--remained motionless. Oudinot, nevertheless, lost two thousand four hundred prisoners. Davoust, from this disaster, returned once more to Hamburg. Girard, who had advanced with eight thousand men from Magdeburg, was, on the 27th, put to flight by the Prussian _Landwehr_ under General Hirschfeld.
