Please read post 65.
PCF 94 was based in Ha Tien and patrolled the Rach Giang Thanh in mid-February 1969, according to the after-action reports on Kerry's website. The Rach Giang Thanh is NEAR Cambodia, but doesn't cross into Cambodia within PCF 94's stated patrol zone.
Kerry was probably in charge of PCF 94 by mid-February.
Thankyou, I did read 65 with keen interest. By putting our heads together we're getting to the bottom of this. Gotta love it.
