(1) 58th CCF Division: Estimated casualties of 3300 for the 172d Regiment; 1750 each for the 173d and 174th Regiments. (2) 59th CCF Division: Estimated 1750 casualties for the 176th Regiment. No other units identified. The known Chinese dead in the two night battles amounted to at least 1500; and if it may be assumed that three or four times that number were wounded, the total casualties would have crippled an enemy infantry division of 7500 to 10,000 men, plus an additional regiment. Considering the primitive state of CCF supply and medical service, moreover, it is likely that hundreds died of wounds and privations behind their own lines. The losses of 3/1 at Hagaru were given as 33 KIA, 10 DOW, 2 MIA, and 270 WIA--a total of 315 battle casualties, nearly all of which were incurred from 28 November to 1 December.[487] There are no over-all casualty figures for Marine or Army service troops, but it is probable that their total losses exceeded those of 3/1.

At 2200 on the night of 1 December, the first survivors, most of them walking wounded, reached the Marine lines north of Hagaru with tales of frightful losses suffered in the five days of continual fighting since the first CCF attack on the night of 27–28 November. Following this action Colonel Allan D. MacLean, commanding the 31st Infantry, had set up a perimeter near Sinhung-ni with the 3d Battalion of his regiment and the 1st Battalion of the 57th Field Artillery. Along the shore farther to the north, Lieutenant Colonel Don C. Faith, USA, held a separate perimeter with the 1st Battalion, 32d Infantry (see Map 20).[488] [488] The sources for the operations of Task Force Faith, unless otherwise noted, are: Statement of Capt Edward P. Stamford, n. d., 2–15; Statement of Dr. Lee Tong Kak, n. d.; Capt Martin Blumenson, USA, “Chosin Reservoir,” in Capt Russell A. Gugeler, _Combat Actions in Korea_, 63–86; X Corps _WD Sum, Nov 50_, 33–34. Chinese accounts of these actions may be found in ATIS _Enemy Documents: Korean Campaign_, Issue 84, 7–15 and 20–25. LtCol Faith had distinguished himself in World War II as aide to MajGen Matthew B. Ridgway, then commanding the 82d Airborne Div. Both positions were hard hit by the Chinese on the night of 27–28 November and isolated from each other. During the next 24 hours they beat off CCF attacks with the support of Marine and FEAF planes, and Faith fought his way through to a junction with the Sinhung-ni force.
