Final answer:
The British had a three-part strategy to isolate New England, dominate the Hudson River, and rally Loyalist support in Southern colonies. However, the failure at the Battle of Saratoga and the unsuccessful southern strategy marked significant strategic failures for the British.
Step-by-step explanation:
The British had a three-part strategy to capture Quebec during the American Revolution. Initially, British forces planned to isolate New England, cutting it off from the rest of the colonies hoping that it would starve into submission. Three armies were to converge from New York City, Montreal, and Fort Oswego along the Hudson River, securing that natural boundary, and thereby isolating New England.
However, their plan faced a setback at the Battle of Saratoga in 1777, resulting in the surrender of British forces. Despite a successful start with the capture of New York City in 1776, the isolation strategy collapsed with General Burgoyne's surrender at Saratoga in October 1777. This significant loss led to the entry of France into the war as an ally of the colonists, which was a crucial turning point in the Revolutionary war.
Finally, the British plan to seize power involved rallying Loyalist support in the southern colonies. They hoped that the support of Loyalists, as well as enslaved people and Native American allies, would help them gain an upper hand, and indeed, this southern strategy initially yielded success with the capture of major cities like Savannah. Nevertheless, this southern strategy would, in the end, prove unsuccessful.
