Count Tarnowski only arrived to the United States on 31 January 1917 as Britain first refused to grant him safe conduct to travel through the Entente naval blockade. Furthermore, he arrived on the same day as the German note on the resumption of unrestricted submarine warfare was delivered and President Wilson therefore refused to receive him. Following the United States. declaration of war with Germany on 8 April, Austria-Hungaria decided to break off diplomatic relations which meant that he was never allowed to present his credentials.
