Who helped weaken the british army?

The American colonists, with significant assistance from France, played a crucial role in weakening the British army during the American Revolutionary War. The French provided military support, supplies, and naval power, particularly after the American victory at the Battle of Saratoga in 1777, which convinced France to enter the war. Additionally, guerrilla tactics employed by American militias and the strategic leadership of figures like George Washington further strained British resources and morale.
