Louis Mountbatten and his wife Edwina were long regarded as Britain’s most glamorous aristocratic couple, close relatives of the royal family and fixtures of high society. But behind the public image lay a private record that American intelligence considered deeply troubling. Declassified FBI files would later describe the pair as persons of extremely low morals, and the bureau had tracked not only their extramarital affairs but also allegations involving Mountbatten’s interest in young boys, including claims that he ran a trafficking ring in Ireland. Mountbatten was born Prince Louis of Battenberg in 1900, a second cousin of King George VI and a child of immense royal privilege.
At his baptism, his godparents included Queen Victoria, his maternal great-grandmother, and Tsar Nicholas II of Russia. During childhood visits to Russia, he became infatuated with his cousin, Grand Duchess Maria, and kept her photograph beside his bed for the rest of his life. He was homeschooled for his first decade, then attended Lockers Park boarding school before entering the Royal Naval College shortly before his thirteenth birthday. The First World War reshaped his family’s standing.
With anti-German feeling rising across Britain, King George V renamed the royal house from Saxe-Coburg and Gotha to Windsor, and German-sounding relatives followed suit. Battenberg became Mountbatten. At sixteen, young Louis enlisted in the Royal Navy as a midshipman on the battle cruiser HMS Lion, seeing action in August 1916 before transferring to HMS Queen Elizabeth near the war’s end. His rise through the ranks owed much to his connections.
He accompanied the future King Edward VIII on royal tours of Australia, Japan, and India, forming a close bond, and later became a deep influence on his great-nephew, the future King Charles III, who called him his honorary grandfather. Mountbatten encouraged the young prince to enjoy the bachelor life, something he himself found hard to give up. On July 18, 1922, he married Edwina Ashley, a wealthy socialite. Their honeymoon took them across Europe and North America, and in California they met Charlie Chaplin and appeared in one of his silent films, Nice and Friendly, which never reached theaters.
The marriage would soon become an open arrangement. Mountbatten later admitted that he and his wife spent their married lives getting into other people’s beds. His professional record was less glamorous. In 1921, as industrial unrest swept Britain, Mountbatten led a platoon of stokers to suppress strikes, despite the fact that many of the men had no experience with rifles.
His interests turned to communications and technology, and he studied at the Portsmouth Signals School and at the Royal Naval College in Greenwich. By 1934 he had his first command of a naval cruiser. When the Second World War broke out in 1939, Mountbatten took command of HMS Kelly. The ship saw action in Norway, the English Channel, and the Mediterranean, but its commander’s mistakes became notorious.
On one occasion he sailed directly into a minefield and rammed another British ship. His bumbling leadership earned him the nickname “the Master of Disaster. ” During the Battle of Crete, the Kelly was finally sunk by German dive bombers. In 1941, during a period of relative inactivity, he visited Pearl Harbor three months before the Japanese attack and reportedly expressed shock at the base’s lack of preparedness, predicting a surprise Japanese strike.
That foresight won him respect from Britain’s highest commanders. In 1942, Mountbatten planned an operation known as the Dieppe Raid. It ended in catastrophic failure, with casualties approaching sixty percent. Still, he continued to rise.
In August 1943, Winston Churchill promoted him to acting full admiral and made him Supreme Allied Commander in Southeast Asia. There, more experienced planning staff repeatedly sidelined his reckless proposals for amphibious assaults. At the Potsdam Conference in 1945, he attempted to court Joseph Stalin by mentioning his family ties to the Russian Imperial dynasty Stalin had helped overthrow. After the war, Mountbatten received high honors, including the titles of Viscount and later Earl.
But the government wanted him out of the way, and on February 20, 1947, he was appointed Viceroy of India. The task was monumental: overseeing India’s transition to independence. His instructions were clear. Britain, now favoring a subtler colonial approach, ordered him to avoid partition and preserve a united India, while giving him flexibility to manage the situation so Britain appeared in the best possible light.
Mountbatten arrived in India on March 22, 1947. Riots immediately broke out in Delhi, Bombay, and Rawalpindi. His advisers favored a gradual transfer of power, but Mountbatten rejected that approach. He believed a slow process would lead to civil war and concluded that a quick, orderly handover was the only way forward.
Mediating between Hindu and Muslim leaders, he concluded that the best course was to partition the country into two independent nations, India and Pakistan, a decision with consequences that still reverberate today. Many opposed the plan, most notably Mahatma Gandhi. Gandhi insisted India remain united and met Mountbatten to press his case. He even proposed inviting Muhammad Ali Jinnah, the future founder of Pakistan, to form a central government.
Mountbatten never relayed the offer to Jinnah. On the night of partition, August 15, 1947, Mountbatten later recalled sitting alone in his study at the Viceroy’s mansion, feeling for a few minutes like the most powerful man on earth. Partition triggered mass migrations as Muslims fled India and Hindus left Pakistan. The haste of the process brought enormous disruption and loss of life.
At the request of India’s new prime minister, Mountbatten became the first governor-general of independent India, guiding many princely states into the central government. He gained admirers in India and remained largely despised in Pakistan, where his attitude toward the country was seen as hostile. He returned to Britain and resumed his naval career, receiving further promotions through the 1950s and serving as First Sea Lord and Chief of the Naval Staff from 1955 to 1959, a position his father had held four decades earlier. Edwina died in 1960 at fifty-eight.
Her widowed husband quickly resumed a pattern of relationships with much younger women, including a long affair with actress Shirley MacLaine. Rumors about his private life followed him throughout his later years, and in 2019 declassified FBI files confirmed that the bureau had long tracked his activities and held its own damning assessment of him. By the 1970s, Mountbatten had settled into retirement. He acquired a summer home in the northwest of Ireland, not far from the Northern Ireland border, where he spent much of his time fishing.
The location made him an easy target. On the night of August 26, 1979, IRA member Thomas McMahon sneaked onto Mountbatten’s boat and planted a radio-controlled bomb. The next morning, Mountbatten and a party of relatives set out on a fishing trip. Just a few hundred yards from shore, the bomb detonated, killing Mountbatten, his fourteen-year-old grandson, and a fifteen-year-old local crew member.
An eighty-three-year-old family friend, the Dowager Lady Doreen Brabourne, died from her injuries the following day.
