What brand tape?
I’ve seen this done by a tech on a DLT7000 drive, maybe on a DLT4000, I think they’re basically the same. I seem to remember the tech used a 9-Volt batter to rewind a stuck tape. The leaders as I recall are very similar for TK50, TK70, and DLTIII.

I've just played around with a TK50-K cartridge and if I jam the two release mechanisms (using the "nose" of two pliers), open the "tape hatch" and gently pull the tape, it moves. Then I can "rewind" it and it's back to the way it was. I'm wondering whether this is safe to do on the DLT III tapes I still want to recover? Is it likely to at least tell me which tapes are likely to fail and which might load properly?
