The British were coming for the privately owned cannon in Concord on April 19th, 1775. Seems it started a war.
You say, "The British", but Paul Revere warned that, "The Regulars are coming out!", meaning the regular army of the King who ruled the colonies. It was their own government attempting to disarm them.
Here's a rough chronology:
1) People in Boston threw tea into the harbor rather than pay a tax.
2) Their own government occupied Boston with the regular army and proposed to stay until the tea was paid for.
3) Citizens opposed their own army's attempts to disarm them outside of Boston.
4) Those same citizens conducted an armed raid against their own government's installation, Fort Ticonderoga, and transported the stolen cannon to Boston.
5) Waking to find their fleet at risk of destruction by means of those stolen cannon, the government agreed to evacuate the occupying army from Boston.
I am totally unconvinced that our Founders intended to require future generations to steal arms from the government, as our Founders had been forced to do, in order to oppose tyranny.
The Second Amendment was not designed merely to permit the people to oppose tyranny. It was meant to discourage even the slightest attempt to impose tyranny.
