Anyone looking at "Hanging on the old barbed wire" who has never been in the armed forces and has no military experience or experience of what the anonymous writer of the song experienced may well assume what they like. The song in it's original version (And there are quite a few of them, nobody knows when they appeared) does not refer to Generals, or Colonels, or Privates but runs through the ranks present in the line.

Sergeant
Quartermaster
Sergeant Major
Lieutenant
C.O.
Battalion (And it is the Battalion that is hanging on the old barbed wire - NOT the Privates)

Not dismissive at all - as they were all in it together.

Certainly nothing dismissive related to military leadership in the ditty "Bloody Orkney", so we seem to be creating a list of songs related to the First World War.

No massive list of songs dismissive of the military leadership of armed forces of the First World War at all as inferred in another thread on this forum by someone on a trolling mission - but that was as I suspected.

Kipling? Goal posts changing are they Gnome?
