William Henry Evered Poole was born in Caledon, Cape Colony on 8 October 1902. He was the son of Major William John Evered Poole, previously of the 60th King's Royal Rifle Corps, and Constance van Breda, a member of one of the best-known Cape Colony families, who had married in October the previous year. As the first-born son, he was given Evered as his last name in accordance with age-old Poole tradition.
In 1927, Poole married Elsie Irene van Boeschoten and had one daughter. After the dissolution of the marriage in 1951, he married Maureen Naish-Gray on 22 October 1951.
Poole transferred to the Permanent Force in 1922. He was placed first on the course for promotion to commissioned rank on 11 September 1923. He was next posted as a lieutenant to the 3rd Battery, South African Field Artillery and transferred to the South African Permanent Garrison Artillery at Cape Town in March 1925, when he again qualified in the first place on a garrison gunnery course. In 1927, he attended a staff duties course at the South African Military College at Roberts Heights and was attached to the South African staff Corps at the college in 1929, again passing out in the first place on a staff duties course of the Permanent Force in 1931. Appointed officer instructor to the Transvaal Horse Artillery for 1931 – 32, he qualified as a captain in the Field Artillery at the end of 1931. In June 1932, he was granted the temporary rank of captain as staff officer, 'A' and 'G', in Cape Town and transferred to the staff corps.
Poole was subsequently posted to the Special Service Battalion as second-in-command with the rank of major. He became the Officer Commanding of the battalion in February 1934. In June 1935, he was granted the temporary rank of lieutenant colonel and was attached to the British Brigade of Guards at Aldershot, in London, and at Pirbright until September 1935. For the rest of the year, he attended the Senior Officers' School at Sheerness. He returned to South Africa to resume command of the Special Service Battalion in 1936.
In October 1937, Poole was transferred to the South African Military College[3] and became Commandant of the college on 16 March 1938. Following the Union's entry into the Second World War in September 1939, Poole organised the greatly expanded facilities at the college, including the huge 'B' Mess dining halls seating 500 officer cadets.[4]
In April 1941, Poole was promoted to the temporary rank of brigadier. In June, he was transferred back to the 1st Division as brigadier to take command of the 2nd South African Infantry Brigade in Egypt. He saw active service with the brigade at Mersa Matruh, commanding 'Braforce' under the 2nd Division on the Egyptian frontier later in 1941, and then with the 1st Division on the Gazala Line from February to May 1942. He returned temporarily to South Africa as officer commanding Cape Fortress until rejoining his brigade at El Alamein in August 1942. There he commanded the brigade in the Second Battle of El Alamein in October–November 1942. He returned to South Africa as second-in-command of the 1st Division.
In 1948, Poole was passed over as Chief of Staff by the newly elected National Party government of Dr D. F. Malan and posted to Berlin to head the South African military mission there. After this he switched to a diplomatic career. He was subsequently appointed envoy extraordinary and minister plenipotentiary to Italy, Greece and Egypt, and in 1954 was transferred to Argentina and Chile. In 1960, he became ambassador to Greece.[5]
In his last years, Poole suffered from a lung ailment which forced his retirement in 1966. In retirement, he spent half the year at his home in Hermanus, Cape Province, and the other half in Greece, aboard the Poole's yacht Estrellita. He died on 9 March 1969.
