THREE:Even the very imperfect means of information supplied by the literature of the empire were not utilised to the fullest extent. It was naturally the writers of most brilliant genius who received most attention, and these, as it happened, were the most prejudiced against their contemporaries. Their observations, too, were put on record under the form of sweeping generalisations; while the facts from which a different conclusion might be gathered lay scattered through the pages of more obscure authorities, needing to be carefully sifted out and brought together by those who wished to arrive at a more impartial view of the age to which they relate.The Battle of Rosbach raised the fame of Frederick wonderfully all over Europe. He soon roused himself, however, for fresh efforts. Whilst he had been thus engaged on the Saale, the Austrians had again overrun Silesia, defeating the Prussians under the Duke of Bevern, storming the great fortress of Schweidnitz, and making themselves masters of Breslau, the capital. In spite of his reduced numbers and the advancing winter, Frederick immediately directed his march towards Silesia, gathering reinforcements as he went, so that by the 5th of December, just one month from the Battle of Rosbach, he came up with Prince Charles of Lorraine and Marshal Daun at Lissa, a small village near Breslau, and with forty thousand men encountered and defeated nearly seventy thousand Austrians, killing and wounding twenty-seven thousand of them, taking above fifty standards, one hundred cannon, four thousand waggons, and much other spoil. This battle at once freed Silesia from the Austrians, who trooped over the mountains in all haste, and left the victorious king to close this unexampled campaign.
