There's at least one date missing there. On 6 Dec Kerry is at Phu Quoc Island which is off the southern coast of Vietnam (if I didn't know that it was Vietnamese, I would have figured that it was Cambodian, due to its western (relative to Vietnam ) location). On 13 Dec, he is assigned to Cam Rahn Bay, which is nowhere near the Mekong Delta. Later entries in this log have him back in the Delta. When is he assigned back to there?
You are absolutely right. CD 11 was at Phu Quoc (An Thoi is on that island) (Been there). CD 13 was at Cat Lo (Vung Tau - Also been there). CD 14 was at Cam Rahn Bay (never got there).
When he was transferd to CD13 from CD11 he actually was sent to Cat Lo, not Cam Rahn Bay. I actually take it as a typo.
What I do not understand is that his "citations" read, While serving as a member of Coast Division ELEVEN, blah blah blah. Yet I see nothing indicating that he was reassigned to CD11. (Apparently they wanted to get rid of him). I remember reading he protested the transfer because he didn't want to sail against the monsoon seas. This was on Dec 13. Problem is that the monsoon season down south is August. December is the 4th driest month of the year, drier than June in Mass.
"On 13 Dec, he is assigned to Cam Rahn Bay"
I had noticed that, but others here think it was a typographical type error for "Cat Lo" - which is in the delta.
