At the other end of the evacuation chain, clearing stations had been established by X Corps at Yonpo Airfield to receive and distribute casualties. A 30-day evacuation policy was maintained, and the casualties to remain in the area went to the 1st Marine Division Hospital in Hungnam, the Army 121st Evacuation Hospital in Hamhung, and the USS _Consolation_ in Hungnam harbor. Casualties requiring more than 30 days of hospitalization were flown from Yonpo to Japan, though a few critical cases were evacuated directly from Hagaru to Japan.[498] [498] _Ibid._ It was planned for incoming transports at Hagaru to fly both supplies and troop replacements. Meanwhile, on 1 December, the 1st Marine Division had its first C-119 air drop from Japan. Known as “Baldwins,” these drops consisted of a prearranged quantity of small arms ammunition, weapons, water, rations, and medical supplies, though the amounts could be modified as desired.[499] [499] Smith, _Notes_, 1001–1004. Col J. H. Brower Comments, n. d. Air drops, however, did not have the capability of supplying an RCT in combat, let alone a division. At this time the Combat Cargo Command, FEAF, estimated its delivery capabilities at only 70 tons per day; and even though in practice this total was stepped up to 100, it fell five short of the requirements of an RCT. Fortunately, the foresight of the Division commander and staff had enabled the Supply Regulating Detachment to build up a level of six days’ rations and two units of fire at Hagaru.[500] This backlog, plus such quantities as could be delivered by Baldwin drops, promised to see the Division through the emergency. [500] Smith, _Notes_, 1001–1004. Infantrymen are seldom given to self-effacement, but at nightfall on 1 December only an ungrateful gravel-cruncher could have failed to pay a silent tribute to the other services as well as to the supporting arms of the Marine Corps. Navy medics, FEAF airmen, Army service units--they had all helped to make it possible for the Marines to plan a breakout. Yet it is likely that the 1st Engineer Battalion came first in the affections of wounded men being loaded in the C-47s for evacuation. In just twelve days and nights the engineers of Company D had hacked this airstrip out of the frozen earth. Marine infantrymen could never forget the two critical nights of battle when they looked back over their shoulders from combat areas at the heartening spectacle of the dozers puffing and huffing under the floodlights. In a pinch Lieutenant Colonel Partridge’s specialists had doubled as riflemen, too, and several platoons were riddled with casualties. Thanks in large part to the engineers, the Hagaru base was no longer isolated on 1 December. And though the enemy did not yet realize it, he had lost the initiative on this eventful Friday. The Marines at Yudam-ni were coming out, and they were coming out fighting with their casualties and equipment. CHAPTER XII Breakout From Yudam-ni
