I highly recommend Rothbard's Conceived In Liberty, Vol. IV (1775-1784). It's available free as an e-book at

Here's an excerpt:
"In short, [George]Washington set out to transform a people's army, uniquely suited for a libertarian
revolution, into another orthodox and despotically ruled statist force after the familiar European model...His primary aim was to crush the individualistic and democratic spirit of the American forces." (p. 43)
