The Inverness-shire RHA was not reconstituted until 7 February 1920 when it formed a battery (later numbered 297th) in 1st Highland Brigade, Royal Field Artillery (later 75th (Highland) Field Regiment, RA) and ceased to be a Royal Horse Artillery battery. In 1939, 297 Field Battery was converted into 297 (Inverness) Heavy Anti-Aircraft Battery, an independent unit that later joined 101st Heavy Anti-Aircraft Regiment and fought in the defence of Scapa Flow and later in the Burma Campaign.
