Kerry's web site has a summary of his exploits thru 1968 into 1969.
For back-up there are, or were, links to spot reports and such...but only starting "January 1, 1969".
Best I can tell there never was posted, ie, released, back up for 1968. Especially December, Christmas.
Coincidence? I think not.
From the Prowler story about the Kerry camp and the media, they knew about the Christmas in Cambodia story and tested its impact with the MSM. I think it is no coincidence they "forgot" 1968.
December 24, 1968 Kerry involved in combat during the Christmas Eve truce of 1968. The truce was three minutes old when mortar fire exploded around Lieutenant Kerry and his five-man crew. Reacting swiftly, John Kerry and his crew silenced the machine gun nest.
