My father joined the Army at 17 and was under fire at the Hadong ambush. He was in the 29th Infantry Regiment. I still have the letter he sent my grandmother afterward.
He turned 18 a week later (the day he wrote the letter).
He mentioned she should not worry even though his unit “
got shot up pretty bad”. He also mentions the village they were in, and it was only about 60 miles south of Pyongyang.

It’s where he got the first of two Purple Hearts.
