Quite true. But the disproportion between the firepower of the patriot militia and that of the British army was a LOT less that between today's unorganized militia and a modern military force.
So is the enemy of the people.
I'm not so sure.
Most cities in the U.S. during the Revolution were located on the coasts and were dependent upon shipping.
The Militia surprised the occupying forces in Boston by taking the big guns from Fort Ticonderoga, dragging them to Boston, and placing them, during the night, on the hills surrounding Boston and Boston Harbor. This enabled the Militia to free Boston and sent their enemy's army and navy scurrying away.
It was not long before the enemy ships showed up in New York and used the surprise provided by their navy's mobility to take New York.
At the end of the war, if not for the timely arrival of the French navy off Yorktown, Virginia, the enemy may have been able to make off in its ships and simply relocate again.
Washington was very careful to avoid LOSING the war in any given battle and was able to survive to see a decisive victory.
Similarly, the people of the U.S. need to simply avoid losing a key battle to eventually win the war against the counter-Revolutionaries who wish to eliminate our right to keep and bear arms.
