Grandfather's death

Shortly after Philip's birth, his maternal grandfather Prince Louis of Battenberg, then known as Louis Mountbatten, Marquess of Milford Haven, died in London. Louis was a naturalized British subject who, after a career in the Royal Navy, had renounced his German titles and adopted the surname Mountbatten—an Anglicised version of Battenberg—during the First World War, owing to anti-German sentiment in Britain. After visiting London for his grandfather's memorial service, Philip and his mother returned to Greece, where Prince Andrew had remained to command a Greek Army division embroiled in the Greco-Turkish War.
