Henry was responding to what he considered wasteful spending of federal and state money for the purchase of arms. He was trying to convince his state of Kentucky to let the federal government purchase the arms in bulk, thus saving both federal and state money. He called the issue double arms when one will do. The issue of militia was worked out so that each state may arm thier own militia but those who receive them from the federal treasuryn would be oopen to call up in case of enemy invasion or insurrection.
