Problem: In this historical fiction book the story is told of how the colonists were able to keep the war going in the face of the British blockade of Boston harbor. The year was 1775, the Revolutionary War was in its early stages, and the colonists were out of ammunition enough to not overthrow the British out of their city. With Boston Harbor blockaded, the colonists could not gain any ammunition, so colonist Henry Knox hears of Fort Ticonderoga stocked with ammunition and devises a plan with his brother Will to bring the guns back to General Washington in the middle of winter. I recommend this book to anyone interested in a historical war book.
Solution:
Positive
