General william t. sherman's "march to the sea" was important to the union war effort because

a) it placed the mississippi river under union control.

b) it convinced great britain to stop supporting the confederacy.

c) important railroad tracks were destroyed, severing supply lines for confederate forces.

d) robert e. lee was forced to surrender his forces as a direct result of sherman's victory.

the answer will be c important railroad tracks were destroyed, severing supply lines for Confederate forces.

the navigation act prevented the colonies from exporting to countries other than britain and it prevented the importation of goods by other countries as well. so i believe the correct answer is d. other nations could not deliver goods to the colonies.
