Did you ever hear the account of the "Dangerous Old Men" that occurred on April 17, 1775?
After the British attempt to take and destroy the muskets/powder/etc. they were looking for in Concord they were fighting their way back towards Boston. They had a cannon or two but had run low on cannon balls and powder for them so they could not use them effectively against the colonial militias that were ripping them a new one along the road.
The spare cannon balls and powder were in a wagon, guarded by some British Regulars and making it's way westward towards the embattled British units that desperately needed them.
You know how the militia was manned? Every male older than about 17 who could fight was in the militia. Once a man became too old, or too crippled up to serve he was no longer considered part of the militia.
Well, a group of these old guys, too old/crippled up to be an active part of their local militia saw this British wagon and it's guards traveling west towards their troops. They decided it would be a good thing if the British cannons did not get resupplied with ball and powder - so they grabbed their muskets and captured the British guards and the wagon and held it to keep the British troops on down the road around Lexington from being able to use them against the militia.
They are/were known as "the dangerous old men".
Never underestimate someone because they are old, small, female, etc.
