After attending Eton, Ponsonby received a commission in the Duke of Cornwall's Light Infantry as a second lieutenant. He transferred to the Grenadier Guards and was promoted to lieutenant on 2 July 1892. He was promoted to captain on 15 February 1899, and served with the 3rd Battalion of his regiment in the Second Boer War. Wounded at the end of the war, he returned to the United Kingdom in April 1902.[1] He was later promoted to major and brevet lieutenant-colonel and served in the First World War. Sir John French mentioned him is despatches. He wrote the standard history: The Grenadier Guards in the Great War of 1914–1918. 3 vols., published in 1920.
Lord Sysonby died in London in October 1935, aged 68, only four months after his elevation to the peerage, and was cremated at Golders Green Crematorium.[19] He was succeeded in the barony by his surviving son Edward. Lady Sysonby, who died in 1955, was denied a pension by George V and was required to vacate St. James’s Palace, where she had lived with her husband throughout their married life.
His autobiography Recollections of Three Reigns, edited and published posthumously in 1951, is full, frank and entertaining. Nancy Mitford wrote to Evelyn Waugh that there was "a shriek on every page".[20][21] He also edited Letters of the Empress Frederick (1928) and published Sidelights on Queen Victoria (1930).
The Ponsonby family has played a leading role in British life for two centuries. His father was Sir Henry Ponsonby who was Private Secretary to Queen Victoria. His grandfather, Frederick was badly wounded at the Battle of Waterloo, but survived to become a British Army general. Lady Caroline Ponsonby, better known to history under her married name of Lady Caroline Lamb, was the wife of the future Prime MinisterLord Melbourne and lover of the poet Lord Byron. This lady was also a key figure in a film – played by Sarah Miles – in 1972. The father of the two siblings, Frederick's great-grandfather, was the 3rd Earl of Bessborough. The man wounded at Waterloo is not to be confused with another Ponsonby depicted on film, his kinsman General Sir William Ponsonby, whose death – possibly due to not risking his best horse in battle – at the hands of a group of lancers is an incident noted in the film 'Waterloo'. Frederick's daughter, Loelia, married the 2nd Duke of Westminster.
