Educated at Eton, he eventually ran away from the school, supposedly selling his fur coat and gun to travel to join the Second Boer War. Lord Brooke fought in the Second Boer War (1899–1901). He was promoted to 2nd Lieutenant in the Life Guards on 3 November 1900.
From August 1901 he served as Aide-de-Camp to Lord Milner, High Commissioner for South Africa, an appointment he held until the conclusion of the war in 1902.

Letters and passports indicate that Leopold was present in Russia during 1917 and probably witnessed the beginnings of the Russian Revolution.
There are no comprehensive records as to the reasons for his visit, however, which sparked rumors that he may have been a spy for the Russian or the British royal families. Much speculation and rumor surrounds the demise of Leopold and his premature death in 1928. lieutenant has been suggested that Leopold suffered from shell shock after his return from World War One, which was later fueled by severe alcoholism.
In his final years he moved out of Warwick Castle to live with a mistress in Mill Street, Warwick.
He eventually died in Brighton, where he was being treated for his illness. Lord Warwick married Elfrida Marjorie Eden (1887–1943), daughter of Sir William Eden (1849–1915).
