Final answer:
When Lincoln made his call to arms, many Northern communities responded with an overwhelming number of volunteers.
Step-by-step explanation:
After the fall of Fort Sumter on April 15, 1861, Lincoln called for seventy-five thousand volunteers from state militias to join federal forces. The response from state militias was overwhelming, and the number of Northern troops exceeded the requisition. Men rushed to enlist, and the Confederacy turned away tens of thousands who hoped to defend the new nation.
The day after the surrender of Fort Sumter, Lincoln called on the states to recruit 75,000 men for ninety days of service to put down the South's rebellion. The response in most states was so overwhelming that the War Department hardly knew what to do with all the recruits.
Hence, When Lincoln made his call to arms, many Northern communities responded with an overwhelming number of volunteers.
