Sales folks -- what would you do in this scenario?

A couple months into a new sales role. We have crystal clear lines drawn as far as segment and territory, with the sales leader reiterating at least once since I've been here that anyone crossing the lines should expect to have their opportunities moved to the rightful owner. Noticed some shady behavior on an incoming account bound for me that someone tried to intercept which got me curious. Found five other deals in flight that are clearly and willfully in violation of the rules. Brought them up with my manager, he sanity checked me and said yes, all five should be yours, so went to my director and the other director in tandem with the information to review and remedy. He seems to believe the other director will make some attempts to keep at least some of the opportunities.

The rules are not new-- they were in place since January of this year with a 3 month transition. There is no possibility for ambiguity on the deals; the reps are quoting well into the threshold I represent. The only explanation is intentional disobedience assuming they wouldn't get caught. The deals would pretty much fill out my entire pipeline for next year (when they would start closing).

If the director doesn't freely comply, my manager is suggesting I might have to pick my battles. I think this is a wild concept that people would even consider keeping deals that aren't theirs just because they stole them awhile ago. If you were in my shoes would you:

A. Accept some kind of compromise from the director to optimize peace where they keep some and I inherit some probably shite ones.

B. Escalate as far as needed to get an answer possibly from the Head of Sales (who would side with me on all). I'd even be willing to split one that is pretty deep in the process out of respect for the work put in.

My inclination is B because I find it absurd that we would reward people for what amounts to theft from a coworker, but could use a few extra takes.

ETA: It is worth noting that my territory was occupied by someone else before I started, and he shifted when I started. They would have been in his name and then transferred to me when I came on board, so it was not an open territory that needed coverage and these guys that have my opps are in a different segment anyway.
