Inter-Service Training and Development Centre facts for kids
The Inter-Service Training and Development Centre (ISTDC) was a department under the British Chiefs of Staff set up prior to World War II for the purpose of developing methods and equipment to use in Combined Operations.
The ISTDC came into being in May 1938 bringing together representatives from the Royal Navy, Army, and Royal Air Force convened with the portfolio of developing methods and equipment to use in Combined Operations.
Origins
The history of amphibious operations in the British Isles reaches back at least as far as Julius Caesar's legions crossing the Channel to invade from Gaul. For centuries the Royal Navy had been landing soldiers on hostile shores, prominent examples being Quebec 1759, Peking 1900, Zeebrugge 1918, and Gallipoli 1915–16. During the inter-war period, however, a combination of recent experience and economic stringency contributed to the delay in procuring equipment and adopting a universal doctrine for amphibious operations.
The costly failure of the Gallipoli campaign during the First World War coupled with the emerging potential of airpower satisfied many in naval and military circles that the age of amphibious operations had come to a close. Still, throughout the 1920s and 1930s, animated discussion in Staff Colleges in Britain and the Indian Army Staff College at Quetta surrounded the strategic potential of the Dardanelles campaign compared with the strategic stalemate of the Western Front. The economic austerity of the worldwide economic depression and the government's adoption of the Ten Year Rule assured that such theoretical talk would not result in the procurement of any equipment.
The Royal Naval Staff College at Greenwich, drafted a document detailing combined operations requirements and submitted it to the Chiefs of Staff on 22 February 1936. Its principal author was the Director of the Staff College, Captain Bertram Watson, RN. The document synthesized the results of all the inter-Staff College studies of preceding years and made specific recommendations that two new organizations should be set up: a Permanent Committee, drawn from all three Service Ministries; and a Training and Development Centre, also to be inter-service.
Another paper from Sir Ronald Adam, Deputy Chief of the General Staff, followed covering similar concerns. In May 1938 the Chiefs of Staff established the Inter-Services Training and Development Centre at Fort Cumberland, near Portsmouth. The Royal Marine contingent was not authorized; but there were four officers representing the three services (and one serving as adjutant), a small clerical staff, direct access to the Deputy Chiefs of Staff, and £30,000 (£10,000 from each of the services).
The original officers appointed to the ISTDC were:
- Captain Loben Edward Harold Maund, RN, Commandant of the ISTDC from 1 July 1938 to September 1939
- Major MWM MacLeod, Royal Artillery
- Wing Commander Guy Knocker, Royal Air Force
- Captain Peter-Picton-Phillips, Royal Marines, serving as Adjutant.
Service history
The ISTDC existed only briefly, from May 1938 to mid-1942 (being briefly disbanded between September and December 1939). The Centre had direct access to the Deputy Chiefs of Staff, and the Joint Intelligence Committee. It was also given authority to seek advice more broadly, contacting service departments such as the Director of Naval Construction with regard to hulls and the School of Musketry at Hythe regarding small arms ballistics. Also, ISTDC engaged private industry such as Fleming about small nesting boats and the Porton Gas School to design a floating smoke bomb.
The Centre was instructed to examine certain specific problems:
- troop landings by air
- air supply of stores and equipment
- craft for landing tanks
- beach organisation
- floating piers
- headquarters ships
- amphibian tanks
- underwater obstacles
- the landing of water and petrol
- the use of small craft in amphibious raids
By the end of 1939 the ISTDC had codified a policy for landings, and defended it at Staff College discussions. Operational experience would suggest modifications to this landing policy, but it would be essentially the policy used in the Torch and Husky landings four years later.
The ISTDC staff went everywhere seeking material and devices and running experiments to discover how sea assaults could proceed. For ships with sufficient speed to become Landing Ships Infantry, the best available was a class of four fast passenger-carrying cargo ships (referred to as "cargo-liners") then under construction for Alfred Holt's Glen Line Far Eastern trade: the Glengyle, Glenearn, Glenroy, and Breconshire. This class could make eighteen knots, be equipped with suitable davits for hoisting out landing craft, and each be adapted to carry a complete battalion, plus some vehicles. They were duly earmarked for commandeering in the event of war.
In March 1942 Louis Mountbatten was promoted to vice-admiral and was appointed to the new position of Chief of Combined Operations (CCO). Soon after, the decision was made to dismember the ISTDC. One part now came under COHQ's newly appointed Director of Experiments and Developments (later Director of Experiments and Operational Requirements, or DXOR). The other part became the Combined Operations Development Centre which in August 1942 was absorbed into the newly established Combined Ops Experimental Establishment (COXE) in North Devon.
