Great to see mention of Major (later Brig-Gen) R M Poore on the White Rose Forum as, to my knowledge, he has no Yorkshire connection.
Coincidentally, I wrote a biography of Major Poore, the Hampshire and South African batsman, which was published in 1992. As previous posts indicate he was most famous for his incredible season of 1899 when he topped the English averages, and established the English 6th wicket partnership record of 411 with E G Wynyard - which still stands. In one week in June 1899 he was the best swordsman at the Royal Tournament and made the winning hit in the Inter-Regimental polo tournament, and hit three successive centuries for Hampshire. He then left England before the end of the season for South Africa where he was assistant to Kitchener as senior military police officer during the Anglo-Boer War.
The book (hardback, 145 pages, 14 photographs) has not been available for 20 years but I still have two copies which I could sell for £10 including P+P if anyone is interested to knowing more about one of the greatest all-round sportsmen of all time. The review below tells more.
