.....McArthur managed to be completely surprised by the Chinese intervention......
Some say USMC Major or was it Captain Ken “Killer” McCoy provided the intelligence of a Chinese buildup but it was ignored by McArthur’s staff and he didn’t learn of it until way after the fact.
I loved those books. Read the entire series in a weekend.
But....he later stuff really got repetitive. I guess you can tell the same story only so many ways.
