As in trying to parry on Hawk’s behalf, or trying to disarm the guard?
A normal halberd is pushing the limits of how big a weapon can be effectively parried with a normal tulwar; these are Very Big halberds. Against a full swing, your sword would snap like a twig.
By rules as written, parrying anything more than three times your weapon weight risks breaking it, anything more than six times guarantees breaking it. These halberds look to be well over twenty pounds.
