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. Since the division had been reduced to approximately 50% of its original strength by this time, it remained in this locality, reorganizing and receiving replacements totalling about 1,200 men. On September 21, 1950, the 5th Division was hit by the full weight of the all-out UN offensive launched in coordination with the successful amphibious operation at Inchon. After the UN breakout from the Pusan Perimeter, fierce battles were fought in the harbor village of Pohang-dong between the ROK 3rd Division and the 5th Division. The 3rd finally captured the village during the morning of 20 September. They continued to attack aggressively, and on September 22, 1950, forced a disorderly withdrawal by the 5th toward Yongdok, where they were once more taken under heavy fire by UN naval vessels. Under orders to withdraw farther north the division left Yongdok on about September 24 with a remaining strength of about 2,400 men. Marching in groups of platoon size and maintaining intervals of about 5 miles between regiments during daytime, the division retraced its route of advance along the coast and arrived at Anbyon on about November 3, 1950. While retreating, several bands of stragglers joined the column en route, boosting its strength to approximately 3,000 men. On October 26, three battalions of the 5th Division had silently crept close to the hill positions of the 1st Battalion, 1st Marine Regiment, guarding a supply dump near Kojo. They attacked so swiftly at one platoon position that fifteen marines were killed there - seven in their sleeping bags. Before noon of the 28th, the 5th Division moved off west into the hills and the fight was over. The marines recovered their dead and counted their losses - 27 killed, 39 wounded and 3 missing. The division arrived in Cheongpyeong on November 8, 1950, and after joining forces with remnants of the 2nd Division, appears to have proceeded, through Hamhung where it swung inland, finally proceeding north along a road that parallels the Tabdong River. On November 18, elements of the greatly diminished 5th Division, with a remaining strength of only 500 troops were seen passing through Sachang-ni moving in a northerly direction. Composition The
