 Soon after, all three regiments were attacked heavily by UN aircraft which wrought considerable damage and disrupted all plans for the attack.Beginning on September 14, 1950, the division was ordered to withdraw from their heavily shelled positions and to regroup in the vicinity of Chongha.When the last elements had withdrawn to the assembly area by September 16, the division was deployed along the Tosong-Dong-Chongha road in well dug-in positions designed primarily to afford protection against the dreaded air attacks which only the day before had blown up the entire ammunition dump of the division artillery.
