Flashback Twilight - The Flashback Saga, #4

The final book in the Flashback Saga ... They streamed out from the tree line in a veritable blitzkrieg, the guns of the tanks rotating and firing, the foot soldiers alternately taking cover behind vehicles and squeezing off bursts, the raptors and triceratops and stegosaurs charging-as Red and Charlotte and Roger and Savanna continued shooting and the children ran ammo and Bella lit the gasoline trenches, as Gojira and the clerk prepared shoulder-mounted rocket launchers.
As hundreds of others joined the battle belatedly and began to kill and to be killed. And then they were there; they were at the gates, and the triceratops and stegosaurs had waded into the burning trenches and begun serving as bridges-sacrificing themselves so that the raptors and the foot soldiers could cross-even as a column of bulldozers fanned out along the perimeter and prepared to break the lines for good: dropping their blades-which rattled and clinked against the hail of gunfire-revving their engines, spewing black smoke."Bayonets!" cried Red as the raptors fell upon them, thrusting his own so that it skewered one of the dinosaurs like a shish kabob even before he used its own weight and momentum to swing it over and behind himself.
