Incidentally, at that time, the State of New England “protested” about this US invasion of Mexico – referring to it as “un-American” on the grounds that the war with England was supposed to have put an end to this type of blatant imperialist activity. The people of New England threatened to “Secede” from the Union (as was their right) if the US moved forward with this plan. The situation was defused by President Polk – who guaranteed NOT to use any military force (amateur or professional) originating within New England – or comprised of New England men (if recruited outside of New England). This agreement prevented New England from “Seceding” – and effectively rendered that State “neutral” for the duration of hostilities.
