My attention was diverted from this death flurry by a furious
yelling, like that of the thing called a siren in our manufacturing
towns.  A man, knee-deep near the towing path, shouted inaudibly to me
and pointed.  Looking back, I saw the other Martians advancing with
gigantic strides down the riverbank from the direction of Chertsey.
The Shepperton guns spoke this time unavailingly.
