Perspective of Native American for westward expansion

Native Americans didn't like it because their land was being taken away. They didn't have many choices. Tribes suffered greatly as the United States government took more and more land. They had to leave the rivers, forests, and mountains and move to a very different topography.

Explanation:

The right answer is Both sides had losses, but it was a victory for the North.

In an attempt to gain foreign recognition and military supplies for the Confederacy, Robert E. Lee decided to invade the North. In September 1862, he and his battle-tested troops pushed north into western Maryland headed for Pennsylvania. The Rebel army encountered Union forces at Antietam Creek near Sharpsburg, Maryland. On September 17, 1862, the Union and Confederate armies commenced the furious Battle of Antietam (Sharpsburg). The next day the battered Confederates slipped south across the Potomac River to the safety of Virginia. General Lee’s northern invasion had failed. It was the bloodiest single day in American history. Some 6,400 soldiers on both sides were killed, and another 17,000 were wounded. President Lincoln was pleased that Lee’s army had been forced to retreat, but he was disgusted by General McClellan’s failure to gain a truly decisive victory by staying engaged with the retreating Confederates.
