The City of Dreadful Night

The Book of the War quoted a poem written by James Thomson in 1874 which included the lines,
 * They have much wisdom, yet they are not wise,
 * They have much goodness, yet they do not well, […]
 * The saddest and the weariest men on earth.

This described his experience as one of the walking dead. (PROSE: The Book of the War)

Behind the scenes
Although the poem isn't named in The Book of the War, the entry on the walking dead quotes 14 lines from Part 11 of The City of Dreadful Night. The poem gives a bleak description of London, just as James Thomson III's journals in The Book of the War describe the Eleven-Day Empire.
