Bas-Lag Wiki
"They were big and soft-bodied, each mass of twisted, bloated tissue coated with intricate flaps and curves of skin, craters and strange, dripping orifices. The central sac was about ten feet in diameter. Each of the creatures had a human rider visible in a harness sutured to the corpulent body. Below each body was a thicket of dangling tentacles, ribbons of blistered flesh that stretched the forty feet or so to the ground."

Men-o'-War are large, floating jellyfish commonly used as mounts by the New Crobuzon militia. Men o' War tentacles are covered with nerve agent, which burns and paralyses anyone unfortunate enough to come into contact with them.


Men-o'-War are often used by the militia as a means of crowd control during riots and protests. Their long, trailing tentacles are useful for disabling and paralyzing protesters for later arrest, although their poison can result in death for anyone who is elderly or allergic.


Events of Perdido Street Station[]

During the events of Perdido Street Station, the militia use Men-o'-War to break up a dockyard strike. Many protestors are paralyzed by the toxin, for later arrest, while a few suffer from cardiac arrest and fall dead.

Events of Iron Council[]

In Iron Council, Men-o'-War are used to suppress anti-Parliament riots while the Tesh-New Crobuzon War wages on. They are used again during the Caucus uprising to disperse gatherings.
