Thomas Barker, writing to his wife Martha on July 6, 1776 expressed the joy of the moment: "We will be the first free people since the Athenians, my love. The honor is ours if we take it!" (1). But in the same letter he admitted his "doubts that England will let such a rich colony go without a war" (2).
At least some colonists were already saving food for the winter (Barker 2).
