Which battle in 1794 led to a decisive U.S. victory and subsequently peace with the Miami Confederacy?

The Battle of Fallen Timbers, fought in 1794, was a significant conflict between American forces and Native American tribes, particularly the Miami Confederacy, in the Northwest Territory. This battle culminated in a decisive U.S. victory under the command of General Anthony Wayne. The outcome played a crucial role in weakening the Miami Confederacy's power and control over the region, which ultimately led to the signing of the Treaty of Greenville in 1795. This treaty established peace between the United States and the Native American tribes and secured American expansion into what is now Ohio.

The other battles mentioned do not relate to this specific context. The Battle of New Orleans took place in 1815 during the War of 1812, and the Battle of Bunker Hill was an early encounter in the American Revolutionary War in 1775. The Battle of Yorktown, also in the Revolutionary War, was pivotal for the surrender of British General Cornwallis in 1781 but did not pertain to the issues involving the Miami Confederacy or the events of the 1790s. Therefore, the Battle of Fallen Timbers is the correct answer as it is directly linked to the resolution of conflicts with Native American tribes following the American Revolution.
