Final answer:
By June, 10,000 British troops are moving south trying to stop the Rebel forces, outlined during the events of the American Revolutionary War where British typically had more troops.
Step-by-step explanation:
By June, 10,000 British troops are moving south trying to stop the Rebel forces. This is in reference to the movements of British and American forces during the American Revolutionary War. Major engagements of the war saw various numbers of troops involved, with British forces often outnumbering the Americans. For example, American commander Major General Benjamin Lincoln faced off against British commander General Sir Henry Clinton with an American force of 5,466 against a British force of 13,500, leading to significant American losses. Another instance involved British forces totaling 20,000 under commanders like Lord Charles Cornwallis and Sir Henry Clinton against an American force of 10,000, resulting in an American loss of 300 and a British loss of 64, indicating a British victory.
Additionally, Great Britain's failed effort in 1777 to isolate New England led to a strategic shift when the occupying British force in Philadelphia evacuated and returned to New York City. This move was made to better defend New York City, and the British then turned their attention to the southern colonies, setting the context for the question about British troops moving south.
