This is a correction, not an addition - the DT version ofWHERE THERE'S REST FOR HORSE AND MAN or HOME LADS HOME has the lines:

For Dick fell at Givenchy and Prince beside the gun
On that red road to glory a mile or two from Munn

But it should be:

For Dick fell at Givenchy and Prince beside the guns
On that red road to glory a mile or two from Mons

^^

The retreat from Mons being one of first major battles involving the British in 1914. So it is a very evocative place-name.
