The Artilleryman is a soldier who tries to enter the Narrator's house after his squadron was wiped out by the martians on Horsell Common. They leave together but get seperated by a Martian attack at Weybridge.
later on in the book we find the Artilleryman in Wimbledon, London. He has gone slightly mad and thinks London can be rebuilt in the drains below. He believes the Martians will turn the humans against each other. The Narrator goes along with his plans until he realises that it is crazy and then leaves the Artilleryman to his own devices.
He also appears in Jeff Wayne's Musical Version of The War of the Worlds where his part is sung by David Essex in the song 'Brave New World' and Later in Live on Stage, Artilleryman is Portrayed by Alexis James, Michael Falzon, and Jason Donovan in 2010 Version. In The New Generation, Artilleryman is Voiced and Sung by Ricky Wilson in Album and Live on Stage.
