But facing that crescent everywhere--at Staines, Hounslow, Ditton,
Esher, Ockham, behind hills and woods south of the river, and across
the flat grass meadows to the north of it, wherever a cluster of trees
or village houses gave sufficient cover--the guns were waiting.  The
signal rockets burst and rained their sparks through the night and
vanished, and the spirit of all those watching batteries rose to a
tense expectation.  The Martians had but to advance into the line of
fire, and instantly those motionless black forms of men, those guns
glittering so darkly in the early night, would explode into a
thunderous fury of battle.
