Seeking battalion logs from my infantry in Viet Nam

I served in the Infantry in Viet Nam from Early February 9, 1969 to February 8, 1970 initially as a combat officer serving with B Company, 1^st Battalion 26the Infantry Regiment, 1^st Infantry Division.  I am seeking battalion logs for incidents, events and enemy contact between February 15, 1969 and May 30, 1969.  I am tracking events resulting in the deaths of some of my men and the actions in which they occurred.

I have reached out to the 1^st ID and have my service records, but these do not contain the detail I am seeking in an effort to track the unit and actions during that period.  Any assistance is appreciated.

Thank you
