The eastern battering ram was the first to fall, as a cannonball detonated inside its cab, tearing apart the drive mechanisms and rupturing the pressure vessel.
The western front had better luck, as the driver had raised the plow-shaped ram to guard his windows. It had taken dozens of hits with minimal damage, but Dominic could see that the vehicle was spewing steam as it approached the gate.
A round must have bounced under the ram and hit the undercarriage.
Dominic couldn't hear the impact over the sounds of battle, but he could see the backside of the western gate, and it didn't buckle after the truck disappeared from sight.
Again, white smoke was beginning to block the view over the wall as the cannons continued to fire. At least the Natural Sons' Regiment wasn't making the issue worse.
Their rifles were all compressed air and magic powered, so they didn't give off the signature white smoke of a black powder firearm.
