Question

president lincoln called for volunteers to join the u.s. military in 1861 in order to:
a. protect northern cities from confederate attacks.
b. force southern states to rejoin the union.
c. destroy all major cities throughout the south.
d. free enslaved african americans being held in the south.

Explanation:

In 1861, after the Southern states seceded, Lincoln called for volunteers to preserve the Union. His initial goal was to keep the country together, not primarily about protecting Northern cities (A) as the war's start was more about secession. Destroying Southern cities (C) wasn't the initial call - for - volunteers reason. Freeing enslaved people (D) became a more prominent goal later with the Emancipation Proclamation, not at the start of calling for volunteers in 1861. The main aim was to force the Southern states back into the Union (B).

Answer:

B. force Southern states to rejoin the Union.
