It's quite a bit more than that. I've seen reports of 40-50 surrendering in just one location alone - smaller numbers in multiple reports from other locations.
I find that tricky to believe. This is a fast operation that is probably quite a bit smaller than the Russians are claiming (they claim 1000 guys). I don’t think Ukraine is going to have the manpower to collect a significant number of prisoners even if they are surrendering.
The numbers I’m seeing now are about 300 prisoners, which seems believable now that Ukraine seems to be doing a ridiculous number of soldiers into Russia
