The correct answer is A, as the Battle of the Horseshoe Bend in 1814 was a turning point in the War of 1812 because as a result of it American Indian power in the region greatly decreased.
The battle of the Horseshoe Bend took place during the Anglo-American War of 1812 in central Alabama, United States. On March 27, 1814, the forces of the United States and their allied American Indians under the command of General Andrew Jackson defeated the "Red Sticks," a part of the Creek Indian tribe led effectively by the Shawnee Tecumseh. This battle ended the War against the Creeks.
On August 9, 1814, Andrew Jackson forced the Creeks to sign the Treaty of Fort Jackson. Despite the protests of the Creek chiefs who had fought alongside Jackson, the Creek Nation passed 93,000 km² - half of Alabama and part of south Georgia - to the United States Government.
