“The fate of unborn millions will now depend, under God, on the courage and conduct of this army. Our cruel and unrelenting enemy leaves us only the choice of brave resistance, or the most abject submission. We have, therefore, to resolve to conquer or die.”
Address to the Continental Army before the Battle of Long Island (27 August 1776)
1770s
Context: The time is now near at hand which must probably determine whether Americans are to be freemen or slaves; whether they are to have any property they can call their own; whether their houses and farms are to be pillaged and destroyed, and themselves consigned to a state of wretchedness from which no human efforts will deliver them. The fate of unborn millions will now depend, under God, on the courage and conduct of this army. Our cruel and unrelenting enemy leaves us only the choice of brave resistance, or the most abject submission. We have, therefore, to resolve to conquer or die.

A few Matters must be dispatched before I can return. Every Colony must be induced to institute a perfect Government. All the Colonies must confederate together, in some solemn Compact. The Colonies must be declared free and independent states, and Embassadors, must be Sent abroad to foreign Courts, to solicit their Acknowledgment of Us, as Sovereign States, and to form with them, at least with some of them commercial Treaties of Friendship and Alliance. When these Things shall be once well finished, or in a Way of being so, I shall think that I have answered the End of my Creation, and sing with Pleasure my Nunc Dimittes, or if it should be the Will of Heaven that I should live a little longer, return to my Farm and Family, ride Circuits, plead Law, or judge Causes, just as you please.
