I have hawthorn over a significant part of my property and I’ve had success with cutting it back to the ground several times in the growing season for several seasons in a row. so long as you cut it back just after it leafs out in the spring and it's small or weak there is a chance it will die. If it is over a small area I’ve also used a shovel or a grubbing axe to cut the roots of the smaller ones to set them back. Unfortunately the only sure fire way I’ve found so far is with a lawnmower, which is problematical with a 20ft tall tree... or for that matter a 4in high stump of fruit wood you just "discovered" with a freshly tuned up mower.
