Hi Verlon!
I have a couple thoughts. Just variations, not necessarily better....
"Dispossessed by the cannon and the gun": feels possibly a little wordy and I wonder if it needs "the" at all? Or maybe just the second "the"? Of course, that would change the rhythm.
"trampled into dust": Not sure. It might be stronger is you said "stomped into dust", but I do like "trampled". Just offering an possible alternative, not really recommending it.
" in all the same damned lies" When I try this out loud, it doesn't flow. It's almost like a tongue twister, so I would expect it to be difficult to sing. But it could just be me and my tongue? "In all the same old lies" would also work and flows easily from my tongue. I realize it doesn't have the same impact, though.
That's all from me.
