The battle occurred soon after a British expeditionary force under the command of Admiral George Brydges Rodney had captured the Dutch colony of Sint Eustatius during the opening stages of the Fourth Anglo-Dutch War, a conflict resulting from tensions between the Kingdom of Great Britain and the Dutch Republic over Dutch support for the American rebels during the Revolutionary War.

The American Revolutionary War (1775–1783), also known as the American War of Independence or the Revolutionary War, was initiated by delegates from the thirteen American colonies in Congress against Great Britain over their objection to Parliament's taxation policies and lack of colonial representation. From their founding in the 1600s, the colonies were largely left to govern themselves. With the capture of New France in the French and Indian War and confirmation of British victory through the 1763 Treaty of Paris, the British government was left deeply in debt, and the colonial legislatures vigorously disputed being forced to pay the expenses of the war. The Stamp Act and Townshend Acts provoked colonial opposition and unrest, leading to the 1770 Boston massacre and 1773 Boston Tea Party. When Parliament imposed the Intolerable Acts upon Massachusetts, twelve colonies sent delegates to the First Continental Congress to organize a boycott of British goods.

The Second Anglo–Mysore War was a conflict between the Kingdom of Mysore and the British East India Company from 1780 to 1784. At the time, Mysore was a key French ally in India, and the conflict between Britain against the French and Dutch in the American Revolutionary War sparked Anglo–Mysorean hostilities in India. The great majority of soldiers on the company side were raised, trained, paid and commanded by the company, not the British government. However, the company's operations were bolstered by Crown troops sent from Britain, and by troops sent from Hanover, which was also ruled by Britain's King George III.

Spain played an important role in the independence of the United States, as part of its conflict with Britain. Spain declared war on Britain as an ally of France, itself an ally of the American colonies. Most notably, Spanish forces attacked British positions in the south and captured West Florida from Britain in the Siege of Pensacola. This secured the southern route for supplies and closed off the possibility of any British offensive through the western frontier of United States via the Mississippi River. Spain also provided money, supplies and munitions to the American forces.

The Battle of Cape Henry was a naval battle in the American War of Independence which took place near the mouth of Chesapeake Bay on 16 March 1781 between a British squadron led by Vice Admiral Mariot Arbuthnot and a French fleet under Admiral Charles René Dominique Sochet, Chevalier Destouches.

The Battle of the Chesapeake, also known as the Battle of the Virginia Capes or simply the Battle of the Capes, was a crucial naval battle in the American Revolutionary War that took place near the mouth of the Chesapeake Bay on 5 September 1781. The combatants were a British fleet led by Rear Admiral Sir Thomas Graves and a French fleet led by Rear Admiral Francois Joseph Paul, the Comte de Grasse. The battle was strategically decisive, in that it prevented the Royal Navy from reinforcing or evacuating the besieged forces of Lieutenant General Lord Cornwallis at Yorktown, Virginia. The French were able to achieve control of the sea lanes against the British and provided the Franco-American army with siege artillery and French reinforcements. These proved decisive in the Siege of Yorktown, effectively securing independence for the Thirteen Colonies.

The Capture of Sint Eustatius took place in February 1781 during the Fourth Anglo-Dutch War when British army and naval forces under General John Vaughan and Admiral George Rodney seized the Dutch-owned Caribbean island of Sint Eustatius.

Following Great Britain's declaration of war on the Dutch Republic in December 1780, British Admiral George Brydges Rodney, the commander of the Royal Navy in the West Indies, was notified by a fast-sailing packet ship of the declaration. He immediately acted to ensure control over as many of the Dutch colonies as possible, capturing Sint Eustatius, a vital entrepot of French and Dutch trade between their colonies and Europe, in early February 1781. He also captured Saba and Sint Maarten, and orchestrated the capture of the Dutch colonial outposts of Berbice, Demerara, and Essequibo in South America.
