A North Korean Puzzle
While the N.K. 2nd Division was making its great effort near the middle of the U.S. 2nd Division line, a sister organization, the N.K. 10th Division, on its left to the north failed to give the assistance that was expected of it in the coordinated corps attack. And therein lies one of the greatest North Korean failures of the war to exploit an opportunity.
The singular behavior of this enemy force puzzled American commanders at the time, although they were thankful that it took the pattern it did. The N.K. 10th Division was the northernmost major organization of the N.K. I Corps.
A large part of it occupied Hill 409 in a deep fold of the Naktong River just west of Hyongp'ung. Elements of this division streamed off Hill 409 the night of 31 August-1 September and struck the 1st Battalion, 38th Infantry, which formed the extreme right flank of the U.S. 2nd Division.
