They leave together but get separated by a Martian attack at Weybridge. He survived the Martian attack by climbing up a storm drain.Later on in the book we find the Artilleryman in Wimbledon, London. He has gone slightly mad and believes that London can be rebuilt in the drains below. He also theorises that the Martians will turn the humans against each other.
