An interest in Public Transport.

How do you measure
The movement of troops
From A to B
When the telephone has not been invented
And Morse code
Is still a pulse in someone’s heart?
How do you know your rations are sufficient
To fill the mouths of invading armies
Hungry for glory?
How do you know they have gathered enough
To keep them alive
Through unknown territory?

You need to measure the footfall
Of an average man
Multiplying it by the hours of walking
Walking straight and narrow
Carving supply lines across the empire.
You try to avoid the delay of Sir Galahad
When the temperature is soaring.
You keep to a schedule
And hope that the post arrives on time.
