  What is Helio in the 16th day? And can someone explain 'The Blues came up as our Machine Gunners' in the 17th day?

  Helio is a shortened version of heliograph - a simple device for signalling using reflected sunlight.

  The Blues is the nickname of the Royal Horse Guards, one of the household cavalry regiments at the time.
