The Royal London Militia was an auxiliary regiment organised in the City of London during the French Revolutionary War from the former London Trained Bands. It later became part of the Royal Fusiliers (City of London Regiment). After conversion to the Special Reserve (SR) under the Haldane Reforms it was one of just a handful of SR units to see combat during World War I, fighting in many actions on the Western Front from 1916 until the Armistice in 1918. After a shadowy postwar existence the unit was finally disbanded in 1953.
