The 1st Airlanding Light Regiment was an airborne forces unit of the Royal Artillery during the Second World War. The regiment was raised in 1943, by the expansion of an existing airborne artillery battery. Attached to the 1st Airborne Division in 1943, the regiment served in Operation Slapstick—part of the Allied invasion of Italy—and then, when the division was withdrawn, it stayed behind to support other Eighth Army divisions in the Italian Campaign until the end of the year. In 1944 the regiment rejoined the 1st Airborne Division in England and, in September 1944, took part in Operation Market Garden, which was the airborne assault in the Netherlands. During the battle of Arnhem that followed the regiment was one of the divisional units that formed a defensive ring around Oosterbeek.
