The friendly Order of Battle for the Pacific is designed to cover the activities of United States units that participated in that area. Therefore coverage of Allied commands and units is limited to such entries as are necessary to give a clear picture of their relationship to U.S. units and vice versa. Although General Stilwell held the positions of Chief of Staff to Generalissimo Chiang Kai-shek, Commanding General USAF CBI, Commanding General, Chinese Army in India, Deputy Supreme Commander, Southeast Asia Command (SEAC), and others, this Record of Events will cover, insofar as possible, only American units and installations in China, Burma, and India that came under his command. UNITED STATES ARMY FORCES CHINA, BURMA AND INDIA (USAF CBI) On 7 December 1941 the United States was represented in China by the American Military Mission to China (AMMISCA). AMMISCA was established at Chungking, China, 4 October 1941 under Brig. Gen. John Magruder, whose mission was, in general, to assist and advise the Chinese Government in all phases of procurement, transport, and maintenance of material, equipment, and munitions requisite to the prosecution of China's military effort. In accordance with an agreement between the governments of China and the United States, General Joseph W. Stilwell was designated by the War Department as Chief of Staff to the Supreme Commander of the China Theater (Generalissimo Chiang Kai-shek). In addition to this position he was appointed as Commanding General of the United States Army Forces in the Chinese Theater of Operations, Burma and India. (It is assumed that the appointment of a Commanding General, USAF, CTO and IB, referred to his commanding of United States personnel in China, India, and Burma, and not the establishment of a Headquarters of a USAF, CTO, IB.) His mission was to increase the effectiveness of United States assistance to the Chinese Government for the prosecution of the war and to assist in improving the combat efficiency of the Chinese Army. General Stilwell's force was designated as The United States Task Force in China and upon arriving in China the units and personnel of the task force and the personnel of AMMISCA were integrated to form Headquarters, American Army Forces, China, Burma and India (AAF CBI). This headquarters was established at Chungking, China, 4 March 1942. On 22 June 1942 all units and individuals under Stilwell's command were relieved from assignment to Army Group, Washington, D.C., and assigned to American Army Forces, India, China, and Burma. The radio from the War Department directing this action was regarded, it appears, as sufficient authority for the establishment of a theater of operation in China, Burma, and India. On 6 July 1942 the command structure of this theater was set up. Headquarters, American Army Forces, China, Burma and India, remained at Chungking, and Branch Office, Headquarters, American Army Forces, CBI, was established at New Delhi, India. (An explanation of the change in sequence of place names in the new command title from AAF ICB to AAF CBI has not been found.) In order to eliminate the possibility of confusing the abbreviation AAF (American Army Forces) with the abbreviation of Army Air Forces (AAF), it became accepted practice to use United States Army Forces, China, Burma and India (USAF CBI). On 24 October 1944 the China, Burma and India Theater was abolished and the China Theater (USF CT) and the India-Burma Theater (USF IBT) were established as separate and distinct theaters. Lt. Gen. Albert C. Wedemeyer commanded the China Theater and also became Chief of Staff to Generalissimo Chiang Kai-shek. The primary responsibility of the Commanding General, USF CT, was to conduct air operations against Japan from China. 4 Mar 42 Hq American Army Forces, China, Burma and India formally established at Chungking, China. 21 Mar 42 Rear Echelon AAF CBI established at Lashio, Burma. 8 Apr 42 Forward Echelon AAF CBI established at Maymyo, Burma. Detachments Hq AAF CBI established at Kunming, China, and Calcutta, India. 23 Apr 42 SOS CBI established at Karachi, India, as a subordinate Command of AAF CBI (See Record of Events SOS CBI). 25 Apr 42 Rear Echelon CP at Lashio, Burma, departed for Paoshan, China; arrived 1 May. 16 May 42 Hq and Hq Squadron Tenth Air Force arrive New Delhi India, and assigned as subordinate command to Hq USAF CBI. 20 May 42 Forward Echelon USAF CBI reached Imphal, India. 30 Jun 42 Ramgarh Training Center established. (See Record of Events for RTC.) 2 Jul 42 Gen. Stilwell designated commander of Chinese Army in India. (See Record of Events for CAI.) 6 Jul 42 Hq USAF CBI organized at Chungking, China. Branch Office Hq USAF CBI organized at New Delhi, India. 18 Jul 42 CG USAF CBI established Branch Office of Hq USAF CBI at Kunming, China, designated as U.S. Kunming Area Command. 5 Nov 42 USAF CBI assumed responsibility for construction of Ledo Road from Ledo to Myitkyina. 24 Nov 42 Branch Office Hq USAF CBI at New Delhi redesignated Rear Echelon Hq USAF CBI (presumably Hq at Chungking became Forward Echelon). (The 24 November 1942 entry indicates that the Branch Office at New Delhi had already been redesignated Rear Echelon. The duplication may be due to the use of the terms "organization," "activation," etc; or it may indicate the change from Headquarters AAF CBI to Headquarters USAF CBI.) 21 Jan 43 Hq USAF CBI Theater was formally divided into Forward Echelon Hq USAF CBI at Chungking, and Rear Echelon Hq USAF CBI at New Delhi, both Hq being activated this date. 21 Jan 43 Hq and Hq Detachment, Chinese Training and Combat Command (CT&CC), activated Ramgarh, Bihar, India, under USAF CBI. (See Record of Events for CT&CC.) 16 Feb 43 Combat Troops, Ledo Sector (APO 689), activated with Hq at Ledo, as subordinate command of USAF CBI, with mission of protecting construction of Ledo Road. 10 Mar 43 Fourteenth Air Force activated with Hq Kunming and placed under operational control of CG USAF CBI. 29 Apr 43 Y-Force Operations Staff (Y-FOS) activated Kunming, China. (See Record of Events for Y-FOS) 1 May 43 Forward Echelon Branch Office USAF CBI established Kunming. U.S. Kunming Area Command discontinued. 5 Aug 43 Joint Army-Navy Intel Collection Agency, CBI (JICA CBI), established and attached to Hq USAF CBI as special staff section. 20 Aug 43 Hq Army Air Force, India-Burma Sector, CBI Theater, activated New Delhi as subcommand of USAF CBI. 10 Oct 43 5307th Composite Regiment (Provisional) organized. (See Record of Events for 5307th Comp Regt (Prov).) 1 Nov 43 5315th Infantry Training Center (Prov) activated Kweilin, China, to train troops of CAI in East China. Assumed to be subcommand of Hq USAF CBI. Disbanded 25 Jul (See Record of Events for 5315th Inf Tng Cen.) 16 Nov 43 CG USAF CBI designated as Deputy Supreme Allied Commander, Southeast Asia (Deputy SACSEA) 31 Dec 43 Branch Office Forward Echelon Hq USAF CBI at Kunming discontinued. 1 Jan 44 Z-Force Operations Staff (Z-FOS) activated at Chungking as subcommand of Forward Echelon Hq USAF CBI. (See Record of Events for Z-FOS.) 1 Feb 44 Northern Combat Area Command (NCAC) activated. (See Record of Events for NCAC). 1 Feb 44 Combat Troops, Ledo Sector, discontinued. 1 Apr 44 Hq USAF CBI (main Hq) established New Delhi. Forward Echelon continued at Chungking; Rear Echelon at New Delhi discontinued. 16 Apr 44 Planning Section, as an additional staff section of Hq USAF CBI, activated. 27 May 44 Mission of USAF CBI as restated by War Department was conduct of such military operations in China as would support main offensive in the Pacific. 17 Jul 44 CG USAF CBI became CG NCAC and retained command of CAI as well. 24 Oct 44 USAF CBI Theater abolished. China Theater (USF CT) and India, Burma Theater (USF IBT) established in its place.
General Stilwell was notified of his relief from responsibilities in Asia by Chief of Staff U.S. Army, 19 October 1944 and departed Chungking 21 October 1944. General Sultan was temporarily in command as of 19 October 1944.
AND SUCCESSOR COMMAND, SERVICES OF SUPPLY, INDIA, BURMA. THEATER (SOS USF IBT) The activation of Services of Supply in China, Burma and India (SOS CBI) was authorized by the War Department on 28 February 1942. The Headquarters and Headquarters Detachment (Provisional), SOS USAF CBI, was activated as a subordinate command of USAF CBI at Karachi, India, 23 April 1942, and on the same date the commanding general and his staff were announced. The mission of the Commanding General, SOS CBI, as directed by the War Department, was to take necessary action required to push equipment and supplies through to General Stilwell; to assume all supply and administrative functions in India necessary to the successful functioning of his command; and to investigate and report upon special supply requirements, supplies locally procurable, special supply difficulties, and the availability of storage space. SOS USAF CBI mission was set forth again on 17 April 1942 by General Stilwell when he directed the Commanding General, SOS, to operate the SOS from base ports in India forward, to include railheads, riverheads, and an airline terminal in Assam; supply all U.S. ground forces in this theater of operations and the U.S. Air Forces to the extent requested by the commanding general of American Air Forces in India; and to receive, warehouse, assemble and transport Chinese lend-lease and other government supplies. Headquarters, SOS USAF CBI, moved from Karachi to New Delhi on 26 May 1942 and on 27 May 1942 it was divided geographically into Base Sections Nos. 1, 2, and 3 and Advance Sections Nos. 1 and 2. On 22 June 1942 it was reorganized geographically into Base Sections Nos. 1 and 2 and Advance Sections Nos. 1, 2, and 3. Base Section No. 3 was organized on 10 December 1942, and Advance Section No. 4 was established 20 March 1943. (For the history of Base Sections and Advance Sections, see the listing at the end of this Record of Events.) On 10 April 1943 SOS USAF CBI was redesignated Army Service Forces, China, Burma, India (ASF CBI) and on 4 June 1943 ASF CBI was redesignated SOS USAF CBI. When the CBI Theater of Operations was abolished on 24 October 1944 and the China Theater (CT) and the India, Burma Theater (IBT) were established as separate commands, SOS consisted of two base sections, one intermediate section and two advance sections. SOS CBI was not redesignated at this time, and Advance Section No. 1 of SOS CBI continued to function virtually independent of SOS CBI as an SOS for CT. SOS CBI was redesignated SOS IBT on 2 November 1944 and Advance Section No. 1 was redesignated CT on 10 November 1944. (See Record of Events for SOS CT.) Effective 21 May 1945, SOS IBT was discontinued and all functions and responsibility of Commanding General, SOS IBT, were assumed by Commanding General USF IBT. On the same date, base, intermediate, and advance sections of SOS IBT, were redesignated base, intermediate, and advance sections of USF IBT and became subordinate commands of USF IBT. 28 Feb 42 SOS USAF CBI authorized by War Department. 23 Apr 42 Hq SOS CBI activated Karachi, India, as a subordinate command of USAF CBI. 26 May 42 Hq SOS CBI moved from Karachi, India, to New Delhi, India. 27 May 42 SOS CBI organized geographically into Base Sections Nos. 1, 2, and 3 and Advance Sections Nos. 1 and 2. (See Record of Events for Base and Adv Sections.) 22 Jun 42 Advance Section No. 3 organized Kunming, China, (see Record of Events for Adv Sec No. 3.) 15 Aug 42 Hq SOS, Ramgarh Training Center, Camp Ramgarh, Bihar, India, placed under direct control of Hq SOS CBI. 1 Sep 42 Procurement Section established as special staff section of SOS CBI. 26 Nov 42 Eastern Section, SOS CBI, established and assigned SOS CBI. (See Record of Events for Eastern Sec.) 20 Mar 43 Advance Section No. 4 established Kweilin, China. (See Record of Events for Adv Sec No. 4.) 6 Apr 43 Transportation Section established as special staff section of SOS CBI. 10 Apr 43 SOS CBI redesignated ASF CBI. 4 Jun 43 ASF CBI redesignated SOS CBI. 2 Nov 43 American Barge Lines, SOS CBI, constituted vicinity Calcutta, India, under supervision and direction of Chief of Transportation, SOS CBI, and assigned SOS CBI. (Date of disbandment unknown.) 17 Dec 43 An Administrative Service established in Hq SOS CBI to direct, control and co-ordinate activities of G-l and G-2, JAG, AG, Finance Officer, Special Services Officer, Chaplain, Provost Marshal, Hq Command, Army Exchange Service, and Public Relations Officer. 1 Jan 44 Transportation Services, SOS CBI, established New Delhi as a subordinate command of SOS CBI. 15 Jan 44 Construction Services, SOS CBI activated as a subordinate command of SOS CBI. 1 Feb 44 General Staff Sections of Hq CBI redesignated as Admin and Operations Sections. Functions of G-l and G-2 assumed by Office of Chief of Admin and functions of G-3 and G-4 by Office of Chief of Operations. 1 Apr 44 China Lend-Lease Section established as special staff section of SOS CBI and responsible through Asst Chief of Operations and Chief of Staff for handling of lend-lease supplies. 1 May 44 China Lend-Lease Section ceased to function as special staff section and was incorporated into Procurement Section. 13 Jun 44 Replacement Service, SOS CBI, established New Delhi as subordinate command of SOS CBI to train and assign replacements in CBI Theater. 13 Jun 44 Burma Road Engineers formed as section of CT&CC with its own T/O and attached to SOS CBI. 15 Jun 44 American Delhi Military Area Command (ADMAC) established as subordinate command of SOS CBI. (See Record of Events for ADMAC.) 30 Jun 44 CO of Advance Section No. 1 (Kunming) designated Deputy to CG SOS CBI in all matters pertaining to SOS functions in China. He was authorized to make decisions for CG SOS in supply matters in China and to report directly to Forward Echelon USAF CBI at Chungking. 11 Aug 44 Admin and Operations Sections of Hq SOS CBI reorganized as follows: Asst Chief of Operations redesignated Deputy CofS for Operations; Asst Chief of Admin redesignated Asst CofS for Admin G-l; Asst Chief of Operations for Troops redesignated Asst CofS for Troops, G-3; Asst Chief of Operations for Supply redesignated Asst CofS for Supply, G-4. 22 Aug 44 Office of Chief Theater Surgeon (USAF CBI) and Off of Surgeon, SOS CBI, consolidated. Surgeon, SOS CBI, designated Deputy Theater Surgeon but continued to function as directed by CG SOS CBI. Sep 44 SOS CBI directed by Hq USAF CBI to assume responsibility for the supply of Y and Z Forces (Chinese troops). 2 Sep 44 Transportation 3ervice, SOS CBI, responsibility for transportation in China vested in Advance Section No. 1. 1 Nov 44 All general and branch depots, and sub depots, formerly under sections, made directly responsible to Hq SOS CBI. 2 Nov 44 SOS CBI redesignated SOS IBT. 19 Nov 44 Chief of Fiscal Section SOS appointed Theater Fiscal Director, and supervision of all fiscal and finance Operations in theater charged to CG SOS IBT. Dec 44 - Feb 45 Special staff sections of SOS IBT and the theater Hq amalgamated. Theater-wide primary responsibility for staff activities had been divided between the two Hq. For example, SOS IBT had theater-wide responsibility for engineering activities and theater Hq had theater-wide responsibility for public relations activities. But in each case the opposite Hq also had a corresponding staff section to perform limited functions of that staff activity; theater Hq had an Engineering Section and SOS IBT had a Public Relations. Amalgamation ultimately eliminated the extra staff section. Thus the Theater Public Relations Officer became in addition to his other duties the Public Relations Officer for SOS IBT while the SOS Engineer acted in addition to his other duties as Engineer for theater headquarters. 11 Jan 45 SOS Engineer Construction Service combined with Theater Engineer Office. Jan 45 SOS Provost Marshal became Theater Deputy Provost Marshall. 7 Feb 45 IBT Signal Officer appointed SOS Signal Officer. 26 Feb 45 Replacement Service relieved from SOS USF IBT and assigned as subordinate command to Hq USF IBT. 14 Mar 45 China Lend-Lease Section re-established in Hq SOS IBT. 23 Apr 45 Information and Education Section IBT transferred to Hq SOS IBT. 21 May 45 Hq SOS IBT discontinued.
Initially, base and advance section commanders were responsible for all engineer construction in their sections and for the handling of supplies for China, India, and Burma. They controlled transportation, depots, ports of debarkation, hospitals, supply, and maintenance, and operating units that were assigned to their sections. However, from time to time certain construction jobs, areas, depots, and other installations within the geographical limits of a section were exempted from the control of a section commander and placed directly under control of Headquarters, SOS. Changes were made in the boundaries of these sections as well as in missions when construction or supply conditions demanded a simplification of administration. 27 May 42 Base Section No. 1 organized with Hq Karachi, India, and assigned SOS USAF CBI. 18 Jul 42 General Depot No. 1 established Karachi under command of CO Base Sec No. 1. 15 May 45 Base Sec No. 1 discontinued.
27 May 42 Establishment of Base Section No. 2 with Hq Bangalore, Mysore, India, authorized. (No personnel assigned however, and it is assumed it did not actually function.) 22 Jun 42 Base Section No. 2 established Calcutta, India. 21 Dec 42 General Depot No. 2 established Calcutta under command of CO Base Section No. 2. 15 May 45 Base Section No. 2 redesignated Base Section S0S IBT. 21 May 45 Base Section SOS IBT redesignated Base Section IBT.
27 May 42 Base Section No. 3 organized Calcutta, India. (Base Section No. 3 did not actually function at Calcutta because of Japanese threats to the ports.) 22 Jun 42 Base Section No. 3 discontinued and its area included in Base Section No. 2. 10 Dec 42 Base Section No. 3 established Ledo, Assam, and assigned SOS CBI. 23 Aug 44 Base Section No. 3 redesignated Advance Section No. 3 (See Record of Events for Advance Section No. 3.)
27 May 42 Advance Section No. 1 organized Agra, India, and assigned SOS CBI. 5 Mar 43 Hq Advance Section No. 1 opened Gaya, India. 11 Mar 43 Intermediate Depot, Farah, organized Farah, India, under control of Advance Section No. 1. 15 Sep 43 Advance General Depot No. 1 activated Gaya, India, and placed under control of Advance Section No. l. 26 Dec 43 Advance Section No. 1 inactivated Gaya. 1 Feb 44 Advance Section No. 1 established Kunming, China. 10 Nov 44 Advance Section No. 1 redesignated Services of Supply, China Theater (SOS CT). (See Record of Events for SOS CT.)
27 May 42 Advance Section No. 2 established Dibrugarh, India. 3 Jul 42 Advance General Depot No. 2 established under command of Advance Section No. 2. 17 Aug 42 Hq Advance Section No. 2 moved to Chabua, Assam, India. 23 Aug 44 Advance Section No. 2 redesignated Intermediate Section No. 2 (INTERSEC No. 2). 15 May 45 INTERSEC No. 2 redesignated Intermediate Section (INTERSEC) SOS IBT. 21 May 45 INTERSEC SOS IBT redesignated INTERSEC IBT.
(Subsequent commanders unknown) 11 Jun 42 Hq Advance Section No. 3 authorized. 22 Jun 42 Hq Advance Section No. 3 organized Kunming, China. 25 Jan 43 Advance General Depot Mo. 3 assigned Advance Section No. 3. 31 Jan 44 Advance Section No. 3 inactivated. 23 Aug 44 Advance Section No. 3 redesignated from Base Section No. 3. 15 May 45 Advance Section No. 3 redesignated Advance Section SOS IBT. 21 May 45 Advance Section SOS IBT redesignated Advance Section IBT.
20 Mar 43 Advance Section No. 4 established with Hq Kweilin, China. 16 Jul 43 Advance General Depot No. 4 activated Kweilin under command of Advance Section No. 4. 31 Jan 44 Advance Section No. 4 inactivated.
The service was established 15 January 1944 at New Delhi, India, and operated under command of the Chief of Engineers, SOS, CBI. 15 Jan 44 Engineer Division No. 1 assigned Construction Service. Engineer Division No. 9 assigned Construction Service. 1 Feb 44 Engineer Division No. 2 assigned Construction Service. 15 Jan 45 Engineer Division No. 12 assigned Construction Service. Construction Service, S0S IBT (Hq of which had functioned as Engineer Special Staff Section) reorganized. Effect of reorganization was transition of Construction Service from a command to a special staff section called Engineer Section and Construction Service.
Eastern Section, SOS was established 26 Nov 42 to receive, store, and issue stocks of Chinese Defense Supplies, Inc. (a Chinese purchasing and supply organization in the U.S.) that were scheduled for the Y-Force. The Eastern Section was without any territorial significance and usually operated from a base at Kunming. It functioned somewhat like a G-4 Section and performed liaison between the American and Chinese SOS in supplying the Y-Force. Another function of the Eastern Section was planning for the rehabilitation of the Ledo Road. 23 Jun 43 Eastern Section SOS CBI was transferred into G-4 Section of Y-FOS.
(It is assumed that the terms center and area were used interchangeably.) 15 Aug 42 Headquarters, SOS, Ramgarh Training Area, Camp Ramgarh, Bihar, India (formerly under Base Section No. 2), was placed under direct control of Headquarters, SOS CBI. Headquarters SOS, RTA, Camp Ramgarh, was responsible for making all administrative arrangements in connection with housing, supply, signal communications, sanitation, and operation of medical services for RTA in addition to supplying and equipping the Chinese forces at Ramgarh. It had no authority over training or tactical operation of the Chinese troops. The senior officer of SOS became the post commander, his functions similar to those of the commanding general of a corps area service command in the United States. 11 Mar 44 All SOS installations and units at RTA, Camp Ramgarh, Bihar, India, placed under direct control of Base Sec No. 2, SOS USAF CBI.
Ramgarh Training Center, an American-staffed, American-operated organization, was established 30 June 1942 by the Commanding General, USAF, CBI, for the training of Chinese troops in India (Supreme Commander, China Theater, had approved Ramgarh, Bihar Province, India, as the site for a training center to train, equip, and reinforce the Chinese troops that had retreated into India from Burma.) 26 Aug 42 RTC formally activated. 1 Feb 43 Hq RTC and Hq Camp Ramgarh combined and CG RTC assumed command. (These two organizations and Hq Chinese Army in India were the three original command organizations at Ramgarh.) Headquarters Ramgarh Training Center was responsible for the training of Chinese Army in India, and Headquarters Chinese Army in India was responsible for the activation, organization, administration, and command of Chinese units. 24 Oct 44 RTC came under control of USF IBT with dissolution of USAF CBI. 15 May 45 RTC discontinued.
21 Jan 43 Hq and Hq Detachment, CT&CC activated Ramgarh, Bihar, India, under USAF CBI as a pool for U.S. officers and enlisted men. 29 Apr 43 Y-Force Operations Staff (Y-FOS) activated to train, organize, and equip Chinese divisions in Y-Force (see Record of Events for Y-FOS). Personnel for Y-FOS was drawn from CT&CC, but Y-FOS was directly subordinate to USAF CBI. 15 Jun 44 Burma Road Engineers Detachment formed as subsection of CT&CC and attached SOS CBI. 24 Oct 44 When USAF CBI was abolished and USF CT established, a portion of CT&CC CBI was within the geographical limits of China Theater. From this organization Y and Z-FOS commands were allotted their personnel. 17 Nov 44 Y and Z-FOS disbanded. That portion of the CT&CC CBI within geographical limits of CT was redesignated CT&CC CT with Hq in Kunming. Personnel of Y and Z-FOS reverted to their original assignment in the CT&CC. 2 Dec 44 Mission of CT&CC CT was to render staff assistance and battle liaison to Chinese armies south of Yangtze River; to assist in training of Chinese Armies involved in plan for defense of Kunming area; to increase the combat effectiveness of Chinese armies. 8 Jan 45 CT&CC CT was split into two separate and component parts: Chinese Combat Command (Prov) and Chinese Training Command (Prov) (CCC (Prov) and CTC (Prov)). In effect, CT&CC CT became a paper organization and the COs of CCC (Prov) and CTC (Prov) reported directly to CG USF CT.
(The commander during the interim period is unknown.) 23 Oct 42 Hq Chinese Army in India (Chin Hui Pu) activated under command of Gen. Stilwell. Function was to handle administration, discipline, and supply of Chinese troops in Ramgarh Training Center (see Record of Events for RTC), While the American staff of RTC handled the equipping and training of the Chinese troops. Apr 43 - Apr 44 During this period most of CAI shifted from Ramgarh to the North Burma front. When combat troops were moved to Assam, Forward Echelon Chin Hui Pu was established at the 5 mile mark along Ledo Road. Ramgarh Hq was designated Rear Echelon Chin Hui Pu. 30 Nov 44 Supreme Commander CT formally placed all Chinese forces in India and Burma (including CAI forces) under over-all command of SACSEA (Supreme Allied Commander, Southeast Asia). 1 Feb 44 Command of all combat units in Assam-North Burma territory (NCAC area) was under Gen. Stilwell in his capacity as CG CAI. Thus there were two separate organizations, CAI and NCAC, with the same staff, and later the same CG (Stilwell), functioning under the over-all command of SEAC in the same area. NCAC had a service mission and CAI had a combat mission. In the summer of 1944 the two organizations became one for Operations. In the fall of 1944 it became the practice to refer to combat forces in this area as NCAC forces; though technically the two organizations were separate. 5 Feb 44 (on or about) 5307th Composite Unit (Provisional) was attached to CAI. 12 Nov 44 Allied Land Forces, Southeast Asia (ALFSEA) was established as subcommand of SEAC and it was agreed to place CAI under operational control of ALFSEA. 16 Dec 44 Rear Echelon CAI moved to Ledo. A sub-Rear Echelon remained at Ramgarh.
(The commander for the interim period following General Stilwell's departure is unknown.) 18 Feb 43 Combat Troops, Ledo Sector (APO 689), activated with Hq at Ledo, as a subordinate command of Hq USAF CBI, with mission of protecting construction of Ledo Road. 1 Feb 44 Combat Troops, Ledo Sector, discontinued and units transferred to NCAC.
Y-FOS was established at Kunming, China, 29 April 1943 by verbal orders of the theater commander. The staff was to work in liaison with the staff of the Chinese Y-Force. (The Y-Force consisted of Chinese troops in Yunnan Province that were to make 30 divisions to be used for combat operations against the Japanese.) Y-FOS was charged with the mission of training, organizing, and supplying the Chinese Y-Force; established priorities for the air movement of supplies and equipment for the Chinese; supervising the Infantry Training Center and the Field Artillery Training Center at Kunming; and formulating plans for the operations and supply of the Chinese Y-Force. 18 Jun 43 Activation of Y-F05 confirmed by verbal orders. 23 Jun 43 Eastern Section SOS becomes G-4 Section of Y-FOS. Y-FOS charged with responsibility for rehabilitation of Burma Road. 24 Oct 44 Y-FOS assigned to CT. 17 Nov 44 Y-FOS disbanded.
*Designated Chief of Staff 29 April 1943 - 17 November 1944. General Stilwell commanded through General Dorn. 1 Jan 44 Z-FOS activated Chungking as a subordinate command of Forward Echelon Hq USAF CBI to train and equip a second 30 Chinese divisions (known as Z-Force) for Operations in East China. 24 Oct 44 Z-FOS assigned USF CT. 17 Nov 44 Z-FOS disbanded.
*General Stilwell commanded through the Chief of Staff Effective 1 February 1944 NCAC was organized with headquarters at Mile 5.5 on the Ledo Road. The Commanding General, NCAC, was responsible for the supervision and direction of all special and service units (Anglo-American) placed in the NCAC, with the exception of SOS units specifically engaged in road construction and the necessary auxiliary and service units. The command of all combat troops in NCAC remained with the Commanding General, CAI. 4 Oct 43 5303d Hq and Hq Co (Prov) Combat troops organized. 29 Jan 44 5303d Hq and Hq Co (Prov) Combat Troops redesignated 5303d Hq and Hq Co (Prov) Area Command. 8 May 44 5307th Comp Unit (Prov) assigned NCAC (See Record of Events for 5307th Comp Unit (Prov).) 16 Jun 44 NCAC passed to operational (assumed) control of SEAC. (Date of release unknown.) 19 Jun 44 Hq and Hq Co NCAC (CT&CC) activated. Personnel allotment for NCAC was granted in order to provide American personnel for Hq and Hq Co NCAC and to provide all liaison personnel with units assigned to Chih Hui Pu (CAI), all American personnel with units assigned to Seagrave Hospital Unit and 1st Tank Group, and American personnel for such other activities as required them. 5303d Hq and Hq Co (Prov) Combat Troops disbanded. 17 Jul 44 CG USAF CBI assumed direct control of NCAC. All Allied units (except Chinese) attached for operational control to NCAC. 26 Jul 44 5332d Brigade (Provisional), known as MARS Task Force, activated 26 Jul 44 and assigned NCAC. Mission of 5332d Brigade (Provisional) was to command long-range penetration units. 5332d Brigade (Provisional) participated in second battle for Burma. 10 Aug 44 475th Infantry activated Ledo and assigned NCAC. 24 Oct 44 NCAC assigned to IBT. CG USAF IBT assumed command of NCAC. 12 Nov 44 NCAC came under operational control of ALFSEA. 10 Jan 45 NCAC Field Replacement Depot established Ledo and assigned NCAC; discontinued 12 Apr 45. CG IBT announced opening of Ledo Road.
The 5307th Composite Unit (Provisional), which was given the code name GALAHAD Force and later nicknamed Merrill's Marauders by the press, was organized to carry out long-range penetration operations. The operations included expeditions to harass the enemy and disrupt his communication and supply line. In addition to these operations the Marauders engaged in normal infantry combat missions in Burma. The 5307th Composite Unit (Provisional) before redesignation was the 5307th Composite Regiment (Provisional). 10 Oct 43 5307th Composite Regiment (Provisional) organized Deogarh, India. 1 Jan 44 5307th Composite Regiment (Provisional) formally activated at Deolali, India, as subordinate command of Hq USAF CBI and redesignated 5307th Composite Unit (Provisional) 2 Jan 44. 5 Feb 44 (on or about) 5307th Composite Unit (Provisional) attached to CAI and assumed further attached to NCAC. 8 May 44 5307th Composite Unit (Provisional) assigned NCAC. 10 Aug 44 5307th Composite Unit (Provisional) disbanded.
5315th Infantry Training Center (Provisional), an American organization, activated Kweilin as subordinate command of Rear Echelon Hq USAF CBI to train officers and enlisted men of Chinese Army in East China. 1 Jan 44 Z-Force Operations Staff (Z-FOS) activated and directed to supervise 5315th Infantry Training Center (Provisional) at Kweilin. 25 Jul 44 5315th Infantry Training Center (Provisional) disbanded.
15 Jun 44 American Delhi Military Area Command (ADMAC) established with Hq at New Delhi, India, under responsibility [sic] of CG SOS CBI. The purpose of this organization was to provide a post Hq with jurisdiction over U.S. Army activities within Delhi Province. 21 May 45 ADMAC SOS USF IBT became ADMAC Hq USF IBT a subordinate command of Hq USF IBT.
Headquarters, United States Forces, India, Burma Theater (USF IBT) was established 24 October 1944 at New Delhi, following the abolition of USAF CBI.

With the abolition of USAF CBI, 24 October 1944, two new theaters were substituted for it: United States Army Forces, China Theater and United States Forces, India-Burma Theater (USF IBT). (See Record of Events for USF IBT). Headquarters, USF CT, was established at Chungking, China. The new headquarters functioned as a part of the Allied Command, China Theater, whose Supreme Allied Commander was Generalissimo Chiang Kai-shek. The JCS issued directives to Headquarters, USF CT, giving it missions within the China Theater. Primary responsibility of Headquarters, USF CT, was to conduct air operations from China. Boundaries of the China Theater included the mainland of China and Indo-China and the islands immediately adjacent thereto, such as Hong Kong, but excluded Formosa and Hainan. The Commanding General, USF CT, commanded U.S. forces within the geographic boundaries of the China Theater with the exception of Headquarters, China Division, India-China Wing, ATC; XX Bomber Command; Naval Group, China, and other quasi-military organizations. Subordinate commands of Headquarters, USF CT, were Y-FOS; Z-FOS; Fourteenth Air Force and Advance Section No. 1, SOS USAF CBI. 10 Nov 44 Advance Section No. 1, SOS CBI, at Kunming, China, redesignated SOS USF CT.

That portion of CT&CC CBI within CT redesignated CT&CC CT with Hq at Kunming. 1 Dec 44 CG CT restated the mission of USF CT to its subordinate commands and detailed new missions for them. USF CT was to defend key installations, air and supply bases in southwestern China. In co-operation with CG USF IBT, USF CT was to develop and protect air and ground lines of communications between India, Burma, and China. USF CT was also to train an effective Sino-American ground team to wage, as early as possible, offensive warfare against the Japanese to secure air bases to support the Pacific offensive. 13 Dec 44 Rear Echelon Hq USF CT established at Kunming. Hq at Chungking became Forward Echelon Hq USF CT. 8 Jan 45 Chinese Combat Command (Provisional) and Chinese Training Command (Provisional) organized as separate and component parts of CT&CC CT.

Central Government was to have full responsibility for problems involved in surrender and repatriation of enemy troops except where the acceptance of surrender was temporarily delegated to U.S. commanders with the approval of Central Government and CG USF CT. CG USF CT directed to support with military assistance operations of Central Government in occupying all areas of China held by Japanese.
SOS CT was redesignated from Advance Section No. 1, SOS IBT, on 10 November 1944 with headquarters at Kunming, China. Initially the SOS CT mission was generally the same as that of Advance Section No. 1: responsibility for supply of American personnel in the China Theater (except for supplies peculiar to the Air Forces), engineering projects, transportation, medical service, communications, and other SOS activities. On 1 December l944 the SOS CT mission was amplified by Headquarters, USF CT, when it directed SOS to be responsible for handling all types of supplies (except those peculiar to the Air Forces) for U.S. troops in China, for Chinese Training and Combat Command forces and Chinese Tactical Air Forces. It was further directed to receive and issue supplies and equipment to Chinese ministries and to maintain records and reports pertaining to lend-lease supplies. Subsequent changes in the mission of Headquarters, SOS, were made as the situation and territorial responsibility demanded. In order to fulfill responsibilities and to promulgate functions of SOS CT, the Chanyi, Kweiyang, Chengtu, and Yunnanyi Area Commands were established on 12 December 1944 and the Paoshan Area Command on 26 December 1944. The Kunming Military Area Command was established on 24 November 1944. On 15 April 1945 most of these area commands were redesignated Base Sections.

(See introduction to Area Commands and Base Sections, SOS CT). 4 May 45 SOS CT received from Hq USF CT a directive stating that SOS primary responsibility was to support U.S. forces in China and Chinese forces within 30 Division Plan (See Record of Events for Y-FOS and Z-FOS). Its secondary mission was to support, advise, assist, and guide Chinese SOS. 4 Jun 45 Communications Zone (CZ) organization established 15 Apr 45, was abolished and reorganized into five Base Sections. (See introduction to Area Commands and Base Sections.) 8 Jul 45 CZ organization of 4 Jun 45 abolished and reorganized. 15 Jul 45 CT Replacement Service organized Kunming and assigned to SOS CT.

SOS CT area commands were established as subordinate commands of USF CT, 12 December 1944. Each area command comprised the territory within a ten-mile radius of the city in which the area command headquarters was established. The area commands were charged with the operation of installations and the enforcement of all directives issued by Headquarters, USF CT, with respect to the conduct and discipline within its area. On 15 April 1945 the term area command was abolished and the CZ (SOS CT area of responsibility) was divided into Base Sections Nos. 1, 2 3, 4, and 5, with headquarters at Yunnanyi, Kunming, Chanyi, Kweiyang, and Chihchiang respectively, and Base Section No. 6, with headquarters as selected by 315th Service Group, AAF (Chengtu).
