British forces under General William Howe defeated Patriot forces under General George Washington at the Battle of Brooklyn in New York.
The agreement about the way to represent enslaved people is the Three-Fifths Compromise of 1787. It was stated in the Constitutional Convention that slaves should be counted as three-fifths of a person, the clause intent to balance the power and influence that the counting of slaves in the Southern could have in elections.
The representatives were defined by the number of population and Southern had many slaves and wanted all of them to be counted as voters but they were still treated as property and were not taxed as free people, because the number of slaves was much bigger in southern than northern states, that already abolished slaving, the northern fought back for a fairly counting for the representatives, so they came to an agreement to count three slaves out of every five slaves regarding the population of each state and for taxation matters.
