Though Sauerwald's intervention lessened the financial burden of the "flight" tax on Freud's declared assets, other substantial charges were levied in relation to the debts of the IPA and the valuable collection of antiquities Freud possessed. Unable to access his own accounts, Freud turned to Princess Marie Bonaparte, the most eminent and wealthy of his French followers, who had travelled to Vienna to offer her support and it was she who made the necessary funds available. This allowed Sauerwald to sign the necessary exit visas for Freud, his wife Martha and daughter Anna. They left Vienna on the Orient Express on 4 June, accompanied by their housekeeper and a doctor, arriving in Paris the following day where they stayed as guests of Marie Bonaparte before travelling overnight to London arriving at London Victoria station on 6 June.
