MAG-12 kept busy at the task of moving men and equipment from Itami and other Japanese fields to Korea. Aircraft of VMR-152, commanded by Colonel Deane C. Roberts, provided transportation. Since safety measures precluded the use of the K-1 runway during construction activity, K-9 substituted temporarily. As fast as the planes unloaded, passengers and gear were trucked 15 miles through Pusan to K-1. It was a transition period in more ways than one for the 1st MAW. Following are the changes of commanders that took place during the last 2 weeks of January: Colonel Radford C. West, relieved by Lieutenant Colonel Paul J. Fontana as commanding officer of MAG-33; Lieutenant Colonel Frank J. Cole, joined MAG-33 staff as personnel officer after being relieved of VMF-312 command by Major Donald P. Frame; Major Arnold A. Lund of VMF-323, relieved by Major Stanley S. Nicolay and assigned to General Harris’ staff as assistant operations officer; Major William M. Lundin, relieved of VMF-214 command by Major James A. Feeney, Jr., and transferred to the command of Service and Maintenance Squadron-33 (SMS-33). This left only Lieutenant Colonel Richard W. Wyczawski of VMF-212 and Lieutenant Colonel Max J. Volcansek, Jr., of VMF(N)-542 still in command of the tactical squadrons they brought to Korea; and the latter was to be relieved by Lieutenant Colonel James R. Anderson in February. The only combat operations of the 1st MAW during the week of housekeeping from 16 to 23 January were carried out by VMF-212 from the deck of the _Bataan_.[55] This CVL carrier alternated with the British light fleet carrier HMS _Theseus_ on the Korean west coast blockade. Their activities were coordinated by Vice Admiral Andrewes, RN, commanding the group blockading the Korean west coast. [55] VMF-212 _HD_, Jan 51; USS _Bataan_ (CVL-29) Action Rpt, “Operations off the West Coast of Korea, 15 Jan-7 Apr 51;” USS _Bataan WD_, Jan 51; Col R. W. Wyczawski, interv of 2 Jun 58. VMF-212 sent out a morning and afternoon reconnaissance flight each day up the coastline as far as the 39th parallel. On the trip north the pilots scanned the coastal waters for small enemy shipping which might indicate reinforcement from Chinese ports on the Yellow Sea. The return trip along the highways and railroads of the littoral was made to detect signs of any new enemy activity on land. Four aircraft flew each of the two coastal sweeps; eight maintained a defensive patrol over the carrier itself; and any remaining flights were under control of JOC, with FEAF Mosquitoes providing liaison between fighter-bombers and ground forces.
