Answer:
Concern for the Continental troops during the winter at Valley Forge.
Step-by-step explanation:
General Washington wrote this letter out of concern for the Continental troops during the winter at Valley Forge. The excerpt reflects his conviction that unless some significant change occurs, the army will face dire circumstances. The mention of the army being reduced to starving, dissolving, or dispersing indicates the severity of the situation. This concern arose due to the harsh conditions and lack of resources faced by the troops at Valley Forge during the winter of 1777-1778. The troops suffered from extreme cold, disease, and shortages of food, clothing, and supplies. General Washington's letter was intended to convey the urgent need for support and provisions to prevent the collapse of the army.
