It's an old-skool military term. Sort of a supersized foxhole or tiny fortress.
Read about the Battle of Bunker Hill. The militia defended from a redoubt, plus some sketchy outworks on the Mystic River side.
We are on to something here and that was very helpful.

Has nothing to do with doubt - as in to deny something.
A
redoubt (historically
redout)
[1][2] is a
fort or fort system usually consisting of an enclosed defensive emplacement outside a larger fort, usually relying on
earthworks, although some are constructed of stone or brick.
[3] It is meant to protect soldiers outside the main defensive line and can be a permanent structure or a hastily constructed temporary fortification. The word means "a place of retreat".
[2] Redoubts were a component of the military strategies of most European empires during the colonial era, especially in the outer works of
Vauban-style fortresses made popular during the 17th century, although the concept of redoubts has existed since
medieval times. A redoubt differs from a
redan in that the redan is open in the rear, whereas the redoubt was considered an enclosed work.

I don't want to move there because as an older person I want to be close to medical facilities.
I plan on staying in Massachusetts.
