The Bolton Artillery, under various titles, has been a Volunteer unit of the British Army based in Bolton, Lancashire, since 1889. In World War I it served in Egypt and Gallipoli in 1915–17, and then on the Western Front for the rest of the war, including Passchendaele, the German Spring Offensive and the Allied Hundred Days Offensive. Just before the outbreak of World War II the regiment formed a duplicate unit. The parent regiment served in the Battle of France and was evacuated from Dunkirk. Both regiments served at the Battle of Alamein and in the Italian Campaign, while one of the regiments was involved in the intervention in Yugoslavia. The regiment was reformed postwar, and after a number of mergers its successors continue to serve in today's Army Reserve.
