About a third of the battles of the American Revolutionary War took place in New York; the first major one (and largest of the entire war) was the Battle of Long Island, a.k.a. "Battle of Brooklyn", in August 1776. After their victory, the British occupied New York City, making it their military and political base of operations in North America for the duration of the conflict, and consequently the focus of General George Washington's intelligence network. On the notorious British prison ships of Wallabout Bay, more American combatants died of intentional neglect than were killed in combat in every battle of the war combined. Both sides of combatants lost more soldiers to disease than to outright wounds. The first of two major British armies were captured by the Continental Army at the Battle of Saratoga in 1777, a success that influenced France to ally with the revolutionaries. The state constitution was enacted in 1777. New York became the 11th state to ratify the United States Constitution, on July 26, 1788.
