Scottish Champion eight times: 1885, 1887, 1892, 1895, 1896, 1897, 1899, 1900.
Because of his profession, Mr Mills was closely associated with chess in various parts of the country; he played for his home county Gloucestershire, for Yorkshire against Lancashire, for Lancashire against Yorkshire, for Scotland against the Northern Counties of England, and for the Southern Union in its Correspondence Matches against the Northern Union.
When living in Bradford, he started a chess column in the Bradford Observer Budget, which he edited until he moved to Manchester.
Mr Mills worked in the insurance business, beginning his commercial career with the Sun Life in London, and then with Clerical, Medical and General in Manchester. Later, he joined the Scottish Equitable Life Assurance Society, which brought him to Edinburgh (he was joint secretary of that Society at the time of his death).
He was clearly the strongest player in the country during his stay in Scotland, but he was also active in organizational matters, being the secretary of the Scottish Chess Association for many years.
Between 1896 and 1903 he competed in every Cable match played between Great Britain and the United States, without losing a game.
