I doubt a 20 man ambush would be enough to stop someone that created the shadow clone jutsu.
Plus considering god like chakra levels, Im guessing he could pull of the multi-clone jutsu just as well.
I think Tobirama could have been sick (think the rare virus Goku had during the android-saga) or severely injured prior to the ambush. It's probably something stupid like that.
Don't put that beyond Kishi, remember when Naruto broke his ankle after hitting a mountain to fast/hard?

A lot of us appreciate some good taijutsu here and there.
