of the remaining C-47s were eventually sent to bases in Burma and continued India-China missions over the lower routes. They proved their continuing usefulness by playing prominent roles in various support missions within China in 1944 and 1945. Between 5 December 1944 and 5 January 1945, C-46s and crews were attached to the Tenth Air Force to augment "Operation Grubworm". This was the relocation of the 14th and 22nd Chinese Divisions, located in reserve on the Stilwell Road near Myitkyina, to bases around Kunming. Chiang and Wedemeyer proposed to the Combined Chiefs of Staff, over the objections of Mountbatten, to relocate the divisions to counter a Japanese offensive seeking to capture the Kunming airfields. The operation was approved with the proviso that it not strain Tenth Air Force's extensive air transport system supplying Allied ground operations in Burma. IDC provided the C-46s of the mobile air transport squadrons and all of its China Wing C-47s to provide the necessary augmentation. The 2nd MATS moved in entirety from its base at Dergaon to Luliang Field, China, completing the deployment by December 13. The 1st MATS operated from Ledo, and ICD's 1348th USAAF Base Unit at Myitkyina South airfield coordinated the entire operation and provided the staging base for refueling all transports. The C-46s moved the 14th Division from five airfields in Burma, including a field at Nansin whose construction was completed December 4. Takeoffs there were subject to artillery and sniper fire. The 1348th Base Unit scheduled operations 24 hours a day and in bad weather, although the operation was suspended between 16 and 22 December when the situation in China seemed improved. Of the six pick-up fields, only Myitkyina South was capable of night operations, and troop carrier C-47s were used to shuttle troops there during the day for ICD aircraft to fly over the Hump at night. The mobile air transport squadrons were familiar with the Burma airfields and so were selected to fly the operation. Showing unusual flexibility in planning, the 1348th Base Unit quartered incoming troops near airfields, supplied them, monitored the availability of aircraft and crews, divided the troops into planeloads, and kept Chinese units and their materiel intact. Briefings and fuelings were conducted at Myitkyina South, the planes flew to their pickup fields and loaded, and then flew back to Myitkyina South for a final refueling before flying on to China.
