Where in any of that Mr. Gardham is there any mention of poor leadership or criticism of officers?

Same with Arthur McBride.

As for the song McCafferty, if the song is true to the story of Patrick McCaffrey then what tyranny? In what way was McCaffrey treated badly? He was ordered to do something and he did not do it. For that he was "confined to barracks with loss of pay" - McCaffrey then decides to kill - he goes through with it, is apprehended and tried and subsequently hanged for the double murder that he undoubtedly committed (Poor hard done by bastard!!!!).

Nobody seems to be able to find any of this supposed plethora of songs about soldiers criticising poor leadership - wonder why - could one possible reason be that whoever it was came out the statement regarding their existence was talking out of his backside and they simply do not exist?
