While RCT-31 was under siege, Almond finally instructed the 1st Marine Division to rescue RCT-31 by breaking out of Yudam-ni, an impossible order for Smith to implement. Only the 31st Tank Company tried to rescue RCT-31 by attacking Hill 1221 from Hudong-ni, but without infantry support, the two armored attacks on 28 and 29 November were stalled by slippery roads, rough terrain, and close infantry assaults. By 30 November, the US forces evacuated Hudong-ni in order to defend Hagaru-ri, leaving the rest of RCT-31 completely stranded.
