Remarkable

I pushed my fried chicken around on my plate, leaned over and took a few sips of my fountain drink, then spoke.
 
"I knew the 1968 episode of Ken Burns' documentary was going to be tough. But I've wanted to know more about what Henry faced during his short time in combat. I wanted to see the terrain, the conditions. But something quite remarkable happened to me during that episode."
 
Andrew cocked his head.

Any guesses what might have transpired for me during that Ken Burns 1968 episode?
