 Fears of a British war with Russia stimulated the formation of more than a dozen volunteer units, including the "Cape Town Highlanders" (1885– )and the "Cape Town Irish Volunteer Rifles" (1885–1891), the "Kimberley Volunteers" (1887–1890), the "Volunteer Medical Staff Corps" (later "Cape Medical Corps") (1889– ), the "Uitenhage Volunteer Rifles" (1892–1913), and several small units in country towns.The Cape Town coast defences were upgraded, and the "Cape Town Volunteer Engineers" converted into the "Cape Garrison Artillery".In 1893, the small country units were grouped together as the "Western Rifles".
