Further tragedy soon followed when Victoria's son, George, died of bone cancer the following year. Her granddaughter, Lady Pamela Hicks, remembered her grandmother's tears. In World War II Victoria was bombed out of Kensington Palace, and spent some time at Windsor Castle with King George VI. Her surviving son (Louis) and her two grandsons (David Mountbatten and Prince Philip) served in the Royal Navy, while her German relations fought with the opposing forces. She spent most of her time reading and worrying about her children; her daughter, Alice, remained in occupied Greece and was unable to communicate with her mother for four years at the height of the war. After the Allied victory, her son, Louis, was made Viscount Mountbatten of Burma. He was offered the post of Viceroy of India, but she was deeply opposed to his accepting, knowing that the position would be dangerous and difficult; he accepted anyway.
