One for "Suppressed", two for "Fall Back", three for" Rout."
Basically just replacements for the coloured counters the game rules say to use. I didn't have any coloured counters but I already had the white flags as morale markers from another game. I think they look a bit better than counters anyway. I kind of like the white flags. Casualty figures would be the ideal thing for me, and I use them when I have them, but sometimes you can't always get what you need in that line, and so I use the flags then.
The little cotton wool smoke puffs are to mark which units have had their go that turn. They used to be Darkest Africa reload markers. Don't see the point of making new stuff when you've already got things that'll do the job.
