In the early days of America as colonies, they were for the most part left to their own devices and defenses. It was therefore necessary that all men kept and bore arms, to protect that which they labored to build and own. It was from this need for a common defense among all the people, that agreements were made to provide able-bodied men to take up arms when an alarm was sounded.
It became necessary then to make formal agreements of association to establish a militia of the people, that is a group of fighting men forming the people's civilian army. They were not an army under the control of a central government, rather they were ordinary men upon who duty deemed it necessary to train and be ready to come to the defense of their fellow colonists.
When the British stopped supplying gunpowder the colonist had to make their own. When the British came to confiscate their arms, the colonists rebelled. There were many other things that were done to the colonists by the Crown, but as loyal subjects, they filed their grievances in the proper manner, and witnessed themselves being treated as less than the subjects in Great Britain were treated. But it was the attempts to take their arms that finally was the last straw or the "shot heard 'round the world"!
So who were the 'Minutemen' and what did they do to earn such a name for themselves? According to American Revolutionary War history they were a select group of well-prepared militiamen, who were so named because of their rapid response to a call-to-arms when they were needed to defend against an enemy attack. Today they would be the Rapid Deployment Forces of an elite military. The Continental Army called up these minutemen for rapid response to British attacks.
So to recap and put it as plain and simple as can be, I am no longer 'duty-bound' to join a militia as I have reached past the age of sixty, however my patriotism and sense of responsibility will keep me 'in the fight' to restore the Republic that has been taken from us all.
In light of the fact that we are being invaded on our southern border, with several reports of Mexican troops crossing and firing upon Americans, that surely looks like an act war, declared or not. Although the federal government is constitutional bound to protect the borders from invasion, they have not only ignored the duty, that are aiding and abetting the invasion!
There have been calls to arm and deploy the militias, to defend the border states from this invasion, but not by the governors of those states. The Governor of Texas has been complaining about the lack of federal support and has asked militias NOT to intervene as the Texas Department of Public Safety will respond. The problem is, they are grossly over-matched for the task.
It will then fall upon the sheriffs of those border counties to call forth the militia, and deputized them to defend the land. It is the duty of We the People to respond to that call, and be prepared to become part of the forces under orders of those officers assigned to lead.
