Much of his cricket was played when he held the rank of Major, but he eventually became a Brigadier-General. "Of all the people in the history of the game," wrote Leo Cooper in an introduction to Associate of Arts Thomson"s Odd Men In, "he seems to stand for the Eccentric Ideal."
He joined the 7th Hussars and served in the Second Matabele War in Rhodesia 1896–1897. In a despatch dated 31 March 1900, the Commander-in-Chief, Lord Roberts, described how Poore "has exercised his responsible duties, whether as regards the care of prisoners, or in maintaining order in camp and on the line of march, in a most satisfactory manner".
In 1899, Poore became the most fertile run-scorer in all of England, hitting 1,399 runs (including seven hundreds) between 12 June and 12 August at an average of 116.58.
Against Somerset he made 304 not out and with fellow Army officer Captain Wynyard shared in a stand of over 400 for the sixth wicket – still the highest for that wicket in county cricket. In 21 innings over the course of the entire season, Poore managed 1,551 runs at 91.23, a record average for an English season not broken until Don Bradman averaged 98.66 in 1930.
Poore returned to South Africa after the 1899 season to fight in the Boer War. After he returned to England, a broken arm caused him to miss most of the 1902 season, but he showed he retained his former skill with a superb innings of 62 not out against Hugh Trumble on a sticky wicket for Hampshire against the touring Australians.
lieutenant was hoped Major Poore would be available again in 1903, but he went to India that summer and when he returned to Hampshire in the middle of 1904 to great expectations, his form was disappointing.
Although there were few difficult pitches in the nine games he played, he averaged under twenty and only once (on a bad wicket against Sussex) did he show the skill that allowed him to dominate bowlers in 1899. In 1905 he again could not play at all, but he rejoined the team against Derbyshire in 1906 and in two matches scored 232 runs including 129 against Sussex, but another injury ended his season and as it turned out, his county career. Not until, as a subaltern, he visited India with the 7th Hussars did he realise his love for cricket, a love that he sustained all through his life.
Poore remained a dangerous batsman in club games right up to his mid-fifties, and played first-class cricket in India as late as 1913.
