Prince Louis was forced to resign from the navy at the start of the war when his German origins became an embarrassment, and the couple retired for the war years to Kent House on the Isle of Wight, which Victoria had been given by her aunt Princess Louise, Duchess of Argyll. Victoria blamed her husband's forced resignation on the Government "who few greatly respect or trust". She distrusted the First Lord of the Admiralty, Winston Churchill, because she thought him unreliable—he had once borrowed a book and failed to return it. Continued public hostility to Germany led King George V of the United Kingdom to renounce his German titles, and at the same time on 14 July 1917 Prince Louis and Victoria renounced theirs, assuming an anglicised version of Battenberg—Mountbatten—as their surname. Four months later Louis was re-ennobled by the King as Marquess of Milford Haven. During the war, Victoria's two sisters, Alix and Elisabeth, were murdered in the Russian revolution, and her brother, Ernest Louis, Grand Duke of Hesse, was deposed. On her last visit to Russia in 1914, Victoria had driven past the very house in Yekaterinburg where Alix would be murdered. In January 1921, after a long and convoluted journey, Elisabeth's body was interred in Jerusalem in Victoria's presence. Alix's body was never recovered during Victoria's lifetime.
