Why was the british navy essential to any british victory in america?

The American Revolutionary War saw a series of military manoeuvres and battles involving naval forces of the British Royal Navy and the Continental Navy from 1775, and of the French Navy from 1778 onwards. These culminated in the surrender of the British Army force of Lieutenant-General Earl Charles Cornwallis, an event that led directly to the beginning of serious peace negotiations and the eventual end of the war. From the start of the hostilities, the British North American Station under Vice-Admiral Samuel Graves blockaded the major colonial ports and carried raids against patriot communities. Colonial forces could do little to stop these developments due to British naval supremacy. In 1777, colonial privateers made raids into British waters capturing merchant ships, which they took into French and Spanish ports, although both were officially neutral. Seeking to challenge Britain, France signed two treaties with America in February 1778, but stopped short of declaring war on Britain. The risk of a French invasion forced the British to concentrate its forces in the English Channel, leaving its forces in North America vulnerable to attacks.

In my honest opinion , i’d say franklin d roosevelt was a president that impacted our nation , i say this because fdr is voted among top three best us presidents and he was the longest serving president by 3 terms , usually presidents only supposed to have two terms increments of 4 years , equivalent to 8 years total before election time. and he established the fdic , through the 1933 banking act and he established the us , social security system , during his presidency, and established a national minimum wage , through the fair labor standards act , fdr led the allied coalition to victory in wwii and he played a major role in the creation of the united nations.
