First of all - Kage is right - recon is the key.
If you have artillery and bombs, fine. If not, then you do it with infantry. Bit no mass assault. You have small teams of specialists with special tasks: taking out a michine gun or destroying a bunker. Use grenades, machine guns, flame throwers etc.. Also try to avoid the main defense and outflank the hill.
In fact, hills are very inportant for the defense, because of the view and the option to place atrillery. But as a matter of fact, hills attract the fire of the enemy, therefore a clever general will only place as few soldiers as necessary. Better to have a strong reserve behind the hill, plus artillery around it.
