These included the 1st Tank Battalion with the exception of the provisional platoon at Hagaru and the 2d Platoon of Company D at Chinhung-ni. Transportation had not yet been provided for the 41st Commando, but the new unit was scheduled to move up in convoy on the 28th with Headquarters Battalion when the Division CP displaced from Hungnam to Hagaru. By that time only service units and a few platoons of tanks and engineers would be left in the rear area. At Hagaru the C-47 airstrip was taking shape as the dozers hacked away at the frozen earth night and day, working under flood lights in the darkness. Companies C and E of the 1st Medical Battalion had set up clearing stations and built up dumps of medical supplies. Troop units at Hagaru and Yudam-ni had two days’ supplies of rations and fuel, but only a unit of fire was stockpiled at Hagaru in addition to the half unit carried by the troops.
