Continental Army and militia forces under the command of General John Sullivan had been besieging the British forces in Newport, Rhode Island, which is situated on Aquidneck Island, but they had finally abandoned their siege and were withdrawing to the northern part of the island. The British forces then sortied, supported by recently arrived Royal Navy ships, and they attacked the retreating Americans.

Document 3: Grattachecca: Grattachecca is a cold dessert originating in Rome, Italy. Commonly sold in kiosks and bars, it consists of hand-shaved ice flavored with various flavors of sweet sciroppo.

Some vendors believe that using a machine is more hygienic compared to hand shaving the ice.
Document 4: American Revolutionary War: British attempts to disarm the Massachusetts militia at Concord in April 1775 led to open combat. Militia forces then besieged Boston, forcing a British evacuation in March 1776, and Congress appointed George Washington to command the Continental Army. Concurrently, an American attempt to invade Quebec and raise rebellion against the British failed decisively. On July 2, 1776, the Continental Congress voted for independence, issuing its declaration on July 4. Sir William Howe launched a British counter-offensive, capturing New York City and leaving American morale at a low ebb. However, victories at Trenton and Princeton restored American confidence. In 1777, the British launched an invasion from Quebec under John Burgoyne, intending to isolate the New England Colonies. Instead of assisting this effort, Howe took his army on a separate campaign against Philadelphia, and Burgoyne was decisively defeated at Saratoga in October 1777.

This was the final battle of the war in North America, and it forced the French to surrender to Lieutenant Colonel William Amherst. The victorious British now controlled all of eastern North America.
