Problem: Please answer a question about the following article about Frédéric Chopin:
Chopin's successes as a composer and performer opened the door to western Europe for him, and on 2 November 1830, he set out, in the words of Zdzisław Jachimecki, "into the wide world, with no very clearly defined aim, forever." With Woyciechowski, he headed for Austria, intending to go on to Italy. Later that month, in Warsaw, the November 1830 Uprising broke out, and Woyciechowski returned to Poland to enlist. Chopin, now alone in Vienna, was nostalgic for his homeland, and wrote to a friend, "I curse the moment of my departure." When in September 1831 he learned, while travelling from Vienna to Paris, that the uprising had been crushed, he expressed his anguish in the pages of his private journal: "Oh God! ... You are there, and yet you do not take vengeance!" Jachimecki ascribes to these events the composer's maturing "into an inspired national bard who intuited the past, present and future of his native Poland."
What year did Chopin learn that the uprising in Warsaw was crushed?
A:
1831
