This article is based on the letters written by the veteran of the Polish 1831 uprising and exile Ignacy Jackowski (1800–1873) to his fellow refugee Leonard Niedźwiecki (1811– 1892). Getting acquainted during their stay in London in early 1830s, they had been regularly writing to themselves after Niedźwiecki’s removal to France in 1839. Jackowski’s letters give a wide and different image of Polish Great Emigration in Britain. They are not only a chronicle of public events but they offer an opportunity to look into bright and dark sides of everyday’s life of the exiles. Jackowski is surprisingly straight and open in his writing. He records events and behaviours which many of his contemporaries prefered to ignore. His letters are now part of Niedźwiecki’s Papers in Biblioteka Kórnicka PAN, Kórnik, Poland.
