How to Destroy Pali Inside Claim

Claim was at least three tiles outside pali in all directions. Had never enlarged place, just moved in and used "as is" (mainly wanted it for its dock in the river, my main place is by a landlocked lake ...where I wasted a day trying to make a jump to the river - "there is no space at the destination").

There was a breach in thingpeace, which I noticed a few hours before it terminated. But I don't know what that meant.
