Randall Garrett, The Measure of a Man
“ Throwing rocks at an army armed with machine guns may seem futile, but if you hit them with an avalanche, they'll go under. The Rats lost three-quarters of their fleet to planet-based guns and had to go home to bandage their wounds.The only trouble was that Earth couldn't counterattack. Their ships were still out-classed by those of the Rats. And the Rats, their racial pride badly stung, were determined to wipe out Man, to erase the stain on their honor wherever Man could be found. Somehow, some way, they must destroy Earth.And now, Al Pendray thought bitterly, they would do it. ”
