When Southern Rhodesia was granted a part-elected Legislative Council, Grey was elected at the
first election in 1899 to represent
Mashonaland. It was subsequently discovered that his supporters had committed
bribery and
treating of potential voters, and Grey resigned in order to be re-elected free of the taint of electoral corruption. Following the outbreak of the
Second Boer War in late 1899, Grey volunteered for active duty as a special service officer, and left
Southampton in the SS
Moor in March 1900, arriving in Cape Town the next month. He was promoted to
major in March 1901 "for command of mounted troops on the occasion of the capture of Boer guns by
Major-General Babington's column". After the war he retired from the Army in 1904, but remained Commandant of the local Volunteers. He established the company Rhodesia Lands, Ltd. to develop mining and farming interests: the 'Jumbo' mine owned by his company became one of the most profitable. He was made a Knight Commander of the Order of the British Empire in 1919. ==Political development==
