1943 to replace 202 HAA Bty. From 24 April to 13 July 1943 165 HAA Bty was detached under command of 1st Medium Rgt. At the end of March 1944 the regiment arrived in Galunche, where it came under the AA Brigade of XXXIII Indian Corps. 86th (Cornwall) Medium Regiment In July 1944, by now under 9 AA Bde at Poona, the regiment underwent a major reorganisation, converting back to the medium artillery role. Initially designated 'B' Medium Regiment, it became 86th (Cornwall) Medium Regiment, Royal Artillery on 15 August, with 165 and 201 Medium Batteries, while 202 Bty, which had just rejoined, provided personnel to 70th (3rd West Lancashire) Battery in 'C' Medium Regiment (later 87 Medium Regiment). The reorganised regiment moved to Secunderabad in September, and then to Ranchi in December, where it joined RA Training HQ No 40. By the end of 1944, the regiment had acquired a section of 7.2-inch howitzers to operate in the medium artillery role, for which it had to find the detachments, command posts and observation post parties. In mid-July 1945, 86 Medium Regiment came under the command of 59th Army Group Royal Artillery, which was training for Operation Zipper, the planned amphibious attack on the coast of enemy-occupied Malaya. However, the Japanese surrendered and the war ended before this operation could take place as planned. 86th Medium Rgt, with 165 and 201 Med Btys, was placed in suspended animation on 1 May 1946. Postwar In 1947 the regiment was reconstituted in the TA as 456 (Cornwall) Heavy Anti-Aircraft Regiment, RA (TA) with its HQ at Redruth and forming part of 81 AA Bde (the old 55 AA Bde based in Plymouth). However, when AA Command was disbanded on 10 March 1955, the regiment was placed in suspended animation, completing the process by 1 July.
