De Gaulle had little success in attracting the support of major figures. Ambassador Charles Corbin, who had strongly supported the mooted Anglo-French Union on 16 June, resigned from the French Foreign Office but retired to South America. Alexis Leger, Secretary-General at the Quai d'Orsay (who hated Reynaud for sacking him) came to London but went on to the US. Roland de Margerie stayed in France despite his opposition to the armistice. De Gaulle received support from Captain Tissier and André Dewavrin (both of whom had been fighting in Norway prior to joining the Free French), Gaston Palewski, Maurice Schumann, and the jurist René Cassin.
