rustbucket: ""[A] citizen volunteered a novel idea to end the siege.
Why not advance to the enemy position behind a movable breastworks of hemp bales?"
Price liked the idea."

Hmmmmmm... where did I see that idea before?...

"We looked down the river and we see'd the British come.
And there must have been a hundred of'em beatin' on the drum.
They stepped so high and they made the bugles ring.
We stood by our cotton bales and didn't say a thing."

Of course, those weren't movable, but didn't somebody else put some on wheels...?

I'd forgotten that [Link].

The Federals did put cotton bales on wheels in Vicksburg, but the Confederates succeeded in setting the bales on fire with incendiary bullets. See: [Link 2].
