From The Journal of Southern History: The British colonies of East and West Florida differed from their thirteen cousins in so many ways, as evidenced especially in the outcome of the American Revolution, that their close relationship to the thirteen in the mind of the British government is seldom realized. For two decades they were an integral part and the important left flank of the British empire in America, without the possession and security of which, as any military man will hold, it were unwise to advance.
