ONE:At ten oclock at night on the 9th of September, the Russian camp went up in flame. The next morning not a Russian was526 to be seen. The whole army had disappeared over the hills far away to the north. Frederick immediately dispatched eight thousand men under General Platen to attack the flank of the retreating foe, and destroy his baggage-wagons. The feat was brilliantly accomplished. On the 15th of September, before the dawn of the morning, General Platen fell upon the long train, took nearly two thousand prisoners, seven cannon, and destroyed five thousand heavily-laden wagons.It is unquestionable that the mental discipline acquired by this elevated course, to which he consecrated so diligently his hours, prepared him for the wonderful career upon which he soon entered, and enabled him to act with efficiency which filled Europe with his renown.
