That is the myth of the American Revolution
Brave Minutemen grabbing their trusty muskets to fight off the British and win our Freedom

Even then, they mostly fought on the defensive.
It was not until the French joined the war and provided well trained troops and more importantly, their Navy, that we were able to defeat the British and gain our independence.
