Burgoyne led a British invasion from Canada toward Albany, aiming to split the colonies. Supply issues, communication failures, and fierce American resistance (Gates, Arnold) led to his surrender at the Battle of Saratoga.
The American victory convinced France to openly ally with the US, providing crucial military and financial aid.
Saratoga's outcome spurred British peace negotiations, culminating in the 1783 Treaty of Paris recognizing US independence.
Despite defeat, Burgoyne was respected for his intellect and leadership, later succeeding in politics and literature.
