Reading edition
"During the short bombardment of Vienna by the French, in 1809, Beethoven was excessively alarmed; he passed most of the time in a cellar at his brother Caspar's, where, besides, he covered his head with pillows that he might not hear the cannon."—Such are the words of M. Ries, p. 121 of his 'Notizen.'
