111th (Bolton) Field Regiment was a Royal Artillery (RA) unit of Britain's part-time Territorial Army (TA) formed just before World War II. It was descended from the Bolton Artillery, first formed in the Lancashire town of Bolton in 1889. After serving in home defence it was sent to the Middle East where it participated in the Second Battle of El Alamein and the Battle of Mareth. It served in the Italian Campaign, and was then transferred to Yugoslavia, fighting alongside Tito's Partisans. The regiment was disbanded at the end of the war.
