Hagaru’s Night of Fire _Four-Mile Perimeter Required--Attempts to Clear MSR--Intelligence as to CCF Capabilities--Positions of Marine Units--CCF Attacks from the Southwest--East Hill Lost to Enemy--The Volcano of Supporting Fires--Marine Attacks on East Hill_ The importance of Hagaru in the Marine scheme of things was starkly obvious after the Chinese cut the MSR. Hagaru, with its supply dumps, hospital facilities and partly finished C-47 airstrip, was the one base offering the 1st Marine Division a reasonable hope of uniting its separated elements. Hagaru had to be held at all costs, yet only a reinforced infantry battalion (less one rifle company and a third of its Weapons Company) and two batteries of artillery were available for the main burden of the defense. Owing to transportation shortages, the 3d Battalion of the 1st Marines did not arrive at Hagaru until after dusk on 26 November. Even so, it had been necessary to leave George Company and a platoon of Weapons Company behind at Chigyong for lack of vehicles.[423] [423] This section is derived from: 1stMar _HD, Nov 50_, 2; 3/1 _SAR, 26 Nov-15 Dec 50_, 2–3; Col T. L. Ridge ltr, 22 Sep 55, and Comments, 7 Jun 56; LtCol E. H. Simmons Comments, n. d. The parka-clad Marines, climbing down stiffly from the trucks, had their first sight of a panorama which reminded one officer of old photographs of a gold-rush mining camp in the Klondike. Tents, huts, and supply dumps were scattered in a seemingly haphazard fashion about a frozen plain crossed by a frozen river and bordered on three sides by low hills rising to steep heights on the eastern outskirts. Although many of the buildings had survived the bombings, the battered town at the foot of the ice-locked Chosin Reservoir was not a spectacle calculated to raise the spirits of newcomers. It was too late to relieve 2/7(-) that evening. Lieutenant Colonels Ridge and Lockwood agreed that Fox Company, 7th Marines, and Weapons Company (-) of 2/7 would occupy positions jointly with 3/1. The hours of darkness passed quietly and relief was completed the next day. Fox Company then moved to its new positions near Toktong Pass. _Four-Mile Perimeter Required_ On the morning of 27 November, of course, an all-out enemy attack was still in the realm of speculation. But it was evident to Lieutenant Colonel Ridge, CO of 3/1, that one to two infantry regiments and supporting arms would be required for an adequate defense of Hagaru. With only a battalion (-) at his disposal, he realized that he must make the best possible use of the ground. For the purposes of a survey, he sent his S-3, Major Trompeter, on a walking reconnaissance with Major Simmons, CO of Weapons Company and 3/1 Supporting Arms Coordinator.
