Final answer:
Three significant events include the Battle of Antietam, leading to the Emancipation Proclamation, the Siege of Vicksburg altering the war's momentum, and the assassination of Abraham Lincoln with substantial effects on U.S. history.
Thus, the correct option is B.
Step-by-step explanation:
You asked about three significant events that happened to Ned or another Marine during the war. The correct answer is: b) The Siege of Vicksburg, the Battle of Antietam, and the assassination of Abraham Lincoln.
The Battle of Antietam was the first major battle of the Civil War to occur on Union soil and is notable for being the bloodiest single day in American history.
The aftermath of this battle led to President Abraham Lincoln issuing the Emancipation Proclamation, which freed slaves in the Confederate-occupied territories. Although it did not free all slaves, it was a pivotal moment that redefined the goals of the war and diminished the prospect of European intervention on behalf of the Confederacy.
The assassination of Abraham Lincoln occurred after the end of the Civil War, which had dealt heavy blows to the Confederacy, particularly with Union victories at key battles such as the Siege of Vicksburg. These events had significant ramifications not just for the outcome of the war, but also for the future of the United States.
Therefore, the correct option is b) The Siege of Vicksburg, the Battle of Antietam, and the assassination of Abraham Lincoln
