During his exile in the United Kingdom, General Fleischer quickly built up a Norwegian infantry brigade based in Dumfries, Scotland from June 1940. However, he soon got at odds with the Norwegian political leadership in exile due to his strong headed attitudes and unwillingness to compromise. He also became controversial in factions of the cabinet due to his support of British commando raids on the Norwegian coast, even stating his willingness to personally participate in the attacks on the German occupying forces in Norway. While stationed in the UK, he received a number of allied awards. Among these were the Polish "Virtuti Militari" for bravery, the French "Croix de guerre", and appointment by the British as a Knight Commander of the Order of the Bath.
