None of this goes through POK (https://en.wikipedia.org/wiki/Azad_Kashmir), could you reference any? If you are thinking of Gilgit-Baltistan (https://en.wikipedia.org/wiki/Gilgit-Baltistan), it got independence from Dogra Raj in 1948 after a short war, then the tug-of-war b/w Pakistan and India and rest is history.
