What is the importance of Valley Forge in the biography, Alexander Hamilton?

Valley Forge, Pennsylvania, is the winter camp of George Washington’s army in the winter of 1777-1778. Hamilton is among those encamped at Valley Forge, where winter conditions, a lack of supplies, and a lack of real support from Congress make a strong impression on Hamilton and his future conception of politics. Valley Forge is where the strongest of Washington’s men remain for combat in the spring, and is where Hamilton takes time to continue his self-education by brushing up on economic theory.
