The Acton minutemen were led by Captain Isaac Davis.When a company was needed to lead the advance on the bridge which was defended by the British regulars, Captain Davis was heard to reply, "I haven't a man who is afraid to go." The Acton men led because, unlike other militias there, they were fully equipped with bayonets.Almost all of Acton is forested, except for where it has been cleared for residential or agricultural use.Some forested areas have been put aside for special use by corporations.In addition, Wills Hole and Grassy Pond are kettle ponds which were formed in depressions in the till formed by large blocks of ice.Acton has two primary stream systems: the Nashoba Brook system including the incoming streams Butter Brook, Will's Hole Brook and Conant Brook and the Fort Pond Brook system including the incoming streams Guggins Brook, Inch Brook, Grassy Pond Brook, Pratt's Brook and Coles Brook.Acton was first settled by Native Americans who used the Assabet, Sudbury and Concord rivers for transportation and the fields for farming seasonal crops.
there were 21,924 residents, a 7.84% increase from 2000 and 5,958 families residing in the town.
Both stream systems empty into the Assabet River, which passes briefly through the town at its southern corner.
Nagog Pond in the north, forms Acton's border with the Town of Littleton and provides drinking water to the Town of Concord.
There were also a powder mill, three gristmills and four sawmills in town. The Fitchburg Railroad was routed through South and West Acton so that it could serve the mills.
South Acton became a busy rail center and was the division point for the Marlborough Branch Railroad.
