Quote context

[...]

- Look! Look! Look over there on the horizon. There are your ants! Look at 'em!

- It was a sight I will never forget.

- Over the range of hills, as far as I could see, crept a darkening hem... ever longer and broader, until the shadow spread across the entire slope, then downward, downward, uncannily swift.

- And all the green herbage on the entire slope was being mowed as by a giant sickle...

- Leaving only the vast moving shadow, extending, deepening... and always moving nearer.

- Heh! They're a hideous lot.

- We can't last against that. Look at them!

- Why, they'll fill your ditches with their corpses and still have enough to destroy every one of us. We've got to run!

- Well, I... No! They haven't gotten to us yet... and they never will.

- The hostile army was approaching in perfect formation.

- No human battalions, however well-drilled, could ever hope to rival the precision of that advance.
