So I just took a woman who fled from tribals (unfortunately she isn't that great and a psychite addict. Though apparently she is the wife of one of my colonist). Right after I got the raid notification a pack of man hunting wargs appeared. I ignored them and finished the tribals. At that point I forgot about the wargs, but right when the tribals flee, the wargs pour in through the choke point and this happens.
The wargs won
