[1] The raid involved a company-sized attack from the newly arrived 1st Battalion, Royal Australian Regiment (1 RAR) on Chinese People's Volunteer Army (PVA) positions on Hill 227.

[1] A Company 1 RAR, under the command of Major David Thomson, was tasked to raid the positions of the PVA 39th Field Army on Hill 227.

With the assaulting troops wearing American issue body armour and with flamethrower and demolition platoons attached, the company gained the top within half an hour and immediately faced heavy and accurate PVA small arms, mortar and artillery fire.

[2] Company headquarters received two direct hits from mortar fire, killing the wireless operator and wounding the artillery forward observation officer and two other members.

[5] Regardless, the preceding artillery bombardment by the 25 pounders had been too light to cause damage to the bunkers on Hill 227 while the two airstrikes planned in support of the operation could not be undertaken due to poor weather.
