Hell On Earth.

The elven kings have discovered that as long as one of them disrupts the gravitational field that contains the plasma ammunition and holds down the target from outside of it, the target within will be able to escape, and the attack will miss. 

This is the major weakness of the Hammer of Dawn. So the elven kings were able to escape the attack. 

But the mortals below couldn't escape from the fallout of that attack being used against them. The ground exploded, and lava submerged them.

It was hell on earth for the mortals. Unfortunately, it was only the beginning.

Command activated the lasers that they sent to low orbit with the satellites that they had launched. This caused pillars of fire to shoot down from the sky on top of the mortals. 

Unlike the hammer of dawn, the pillars of fire had a more contained damage range. So Command was able to use them to target the elven army alone. However, any human soldier in their paths would be incinerated too.
