in late October 1943 to take over the air defence of Naples. The defended area over the port, the anchorages and adjacent airfields was declared an Inner Artillery Zone (IAZ), giving AA guns priority over fighters at night. The problem of radar coverage of the Bay of Naples was partly solved when the new centimetric Mk. III GL radar became available. Luftwaffe raids over the city were frequent and heavy during November. The deployment at Naples turned into a long-term commitment. Heavy air raids resumed in March 1944, after which they progressively declined, and AA defence strength was also reduced, though 58th HAA Rgt remained there until the end of the war in Europe. 58th HAA Rgt with 207, 208 and 264 HAA Btys was placed in suspended animation on 15 December 1945. Postwar The regiment was reconstituted in the TA on 1 January 1947 as 458 (Kent) (Mixed) Heavy Anti-Aircraft Regiment, RA (TA) ('Mixed' indicating that it included members of the Women's Royal Army Corps). The regimental HQ was now at Sidcup, and it was attached to 54 AA Bde (the old 28th (Thames and Medway) AA Bde) until that formation was disbanded the following year. AA Command was disbanded in 1955 and there was a considerable reduction in AA units: 458 HAA was amalgamated with 564 (Mixed) Light Anti-Aircraft/Searchlight Regiment and 608 (Kent) (Mixed) Heavy Anti-Aircraft Regiment to form a new 458 (Kent) Light Anti-Aircraft Regiment, RA (TA) with the following organisation: RHQ Battery – from 608 Regiment P Battery – from 458 Regiment Q Battery – from 564 Regiment R Battery – from 564 Regiment S Battery – from 608 Regiment The regiment formed part of 30th Anti-Aircraft Brigade, a TA formations whose headquarters was at Edenbridge, Kent. In 1961, 458 Regiment (less one battery that merged into 211 (Thames & Medway) Field Squadron, Royal Engineers) amalgamated with 265 LAA and 570 LAA regiments, forming P (Kent) Battery in a new 265 LAA Regiment. Further reorganisation saw P (Kent) Battery, representing the whole of 265 Regiment, absorbed into a new London and Kent Regiment (TA), but when this was reduced to a cadre in 1969 the 4th Home Counties lineage disappeared. Successor units still occupy Grove Park and Bexleyheath drill-halls, as 265 (Home Counties) Battery, 106th (Yeomanry) Regiment, Royal Artillery and 265 (Kent and County of London Yeomanry) Support Squadron, Royal Corps of Signals. Both units strive
