Why would the Union focus on blockading the port of Savannah during the Civil War? Select the two that apply

There are several reasons why the Union would focus on blockading the port of Savannah during the Civil War. However, since you requested to select two reasons, the following are the most significant:

1) Disrupting trade and supply lines: Blockading the port of Savannah aimed to cut off the Confederacy's access to vital imports and exports. Savannah was a major port for the Confederate states, and by blockading it, the Union hoped to cripple their economy and prevent them from receiving necessary supplies.

2) Preventing reinforcements and resources: By blockading Savannah, the Union intended to prevent the Confederates from receiving reinforcements and resources. It would hinder their ability to send troops, ammunition, weapons, and other crucial supplies from the port to support their war effort.

The South got money, food, arms, ammunition, even clothes .... in by shipping unwoven cotton out. I am not aware of them shipping soldiers in or out.

Apologies for any confusion caused. You are correct that the main purpose of the blockade was to disrupt the South's trade and supply lines, as well as to prevent them from exporting cotton in exchange for much-needed goods. Therefore, the two reasons for the Union focusing on blockading the port of Savannah during the Civil War would be:

1) Disrupting trade and supply lines: By blocking the port of Savannah, the Union aimed to choke off the South's access to vital imports such as manufactured goods, medicine, and other resources necessary for their war effort. In particular, the export of unwoven cotton was key for the South's economy, and blockading the port of Savannah would hinder their ability to trade and obtain essential supplies.

2) Preventing the export of cotton: The South relied heavily on the export of cotton to finance their war effort and acquire necessary goods. By blockading the port of Savannah and other southern ports, the Union sought to cut off this crucial source of revenue, weakening the Confederate economy and reducing their ability to sustain the war.
