On the 16th the two vessels departed according to schedule by way of Port Said and the Suez Canal. Security regulations were rigidly enforced, with only one stop being made when the vessels anchored at Ceylon for six hours to take on fuel. Marine officers were figuratively as well as literally at sea, since they had no idea of the specific mission awaiting the battalion in the Far East. Unaware of plans for the Inchon landing, they envisioned the troops being employed as the ship-based raiding party of some American task force. Meanwhile their future teammates of the 7th Marines were preparing to embark from San Diego. Colonel Litzenberg and his officers had made a good start at Camp Pendleton even before the activation date of 17 August 1950. In order to build up from cadres of former 6th Marines’ troops, this regiment received the largest proportion of combat-ready reservists of any major unit in the 1st Marine Division--about 50 per cent, counting the augmentation personnel to bring 3/6 up to war strength when it would be taken into the outfit in Japan.[83] [83] Giusti, II-5. CNO had set 3 September as the date of embarkation. But Headquarters, FMFPac, prepared the embarkation plans while the regimental staff solved problems of organization and equipment so effectively that the 7th Marines sailed on the 1st, thus beating the deadline by two days.[84] [84] PacFlt _Interim Rpt No. 1_, XV: Zebra, 15. Orders came to El Toro on 16 August for the overseas movement of the remaining elements of the 1st MAW. Units affected were Wing Headquarters Squadron 1 and MAG-12, comprising Headquarters Squadron 12, Service Squadron 12, VMF-312, VMF-212, VMF(N)-542, and the rear echelon of VMF(N)-513. VMF-312 and the rear echelon of VMF(N)-513 were loaded on the USS _Sitkoh Bay_ with their aircraft and sailed on 24 August. Three days later VMF-212 and VMF(N)-542 embarked on the USS _Cape Esperance_, and the USNS _General Morton_ weighed anchor with the remaining components on 1 September.[85] This completed the overseas movement of the 1st MAW, since General Harris and his staff had departed from El Toro by air for Japan the day before. [85] _Ibid._, XV: Charlie Charlie, 4. _Working Around the Clock_ The first echelon of the 1st Marine Division planning group had its preliminary briefing on 19 August, and the tractor elements of the Attack Force were scheduled to sail for the objective area on 9 September. This left an interval of 20 days for most of the Inchon planning--probably the shortest period ever allotted to a major amphibious assault. Less than one-fourth of the officers and men of the 1st Marine Division staff were on the _Mount McKinley_ when planning commenced. At that time the distribution of the staff was as follows:
