During the November 1830 Uprising against the Russian Empire, British military equipment and armaments were sent to Poland, facilitated by the presence of Leon Łubieński studying at Edinburgh University at the time and the swift despatch to Britain of his uncle, Józef, to secure the shipment. After the collapse of the rebellion in 1831, many Polish exiles sought sanctuary in Britain. One of them was the veteran and inventor, Edward Jełowicki, who took out a patent in London on his Steam turbine. The fall of Warsaw and the arrival of the Polish on British shores prompted poet Thomas Campbell with others to create in 1832 a Literary Association of the Friends of Poland, with the aim of keeping British public opinion informed of Poland's plight. The Association had several regional centres; one of its meetings was addressed by the Polish statesman, Count Adam Jerzy Czartoryski. Czartoryski's permanent representative at the Court of St James's was General Count Władysław Stanisław Zamoyski, who later led a division in the Crimean War on the British side against Russia. Zamoyski's adjutant was another Polish exile, an officer in the 5th Sultan's Cossacks—a Polish cavalry division—Colonel Stanisław Julian Ostroróg. The last official Polish envoy to Britain was the statesman, writer, and futurologist, Julian Ursyn Niemcewicz (1758–1841).
