- ↑ Translation notes: The mention of the fortifications of Liège is a pun on "liège" - cork. I have translated "pneumatique" throughout as telegram for want of a better word, even though the messages were not strictly speaking actual telegrams. The pneumatic postal system transferred messages, or "petit bleus", across Paris through compressed air tubes in the late 19th and early 20th century.
