No pawn taken

I wondered if there has been a game with the two armies crossing without a single pawn being taken ?
A bonus is if there has been no mistakes made...

I remember that I once signalled a win for me still having all my stones, but cannot remember if I took an opponent's stone.

Checking over the game records of people who played in the infinite tournament (131 players, yielding 177688 games), I found exactly two:

There could, of course, be more.

Thanks William for your research.
They seem quite rare.
I guess they are not possible with perfect play, I tried to find starting positions where it makes sense, but did not succeed.

It would be strange in the beginning to keep a 2,3,4,5 of you are able to self capture. Of course the added condition on optimal play is vague.
