This volume is the result of an international symposium held at the School of Slavonic and East European Studies, University of London, on 26 and 27 September 1983. The symposium was ar-ranged to commemorate the fortieth anniversary of General Sikorski's tragic death at Gibraltar in July 1943. It developed from the work of the M.B. Grabowski Research Project, dealing with the history of Poles in Britain during the years 1939-50, and was chaired jointly by Professor M.R.D. Foot and by the late Professor Hugh Seton-Watson.
