Answer:
depending on the year A and D
Step-by-step explanation:
www.nps.gov says: In July 1861, the two armies were nearly equal in strength with less than 200,000 soldiers on each side; however at the peak of troop strength in 1863, Union soldiers outnumbered Confederate soldiers by a ratio of 2 to 1. The size of Union forces in January 1863 totaled over 600,000. Two years later, that number had not changed dramatically for the Union Army but had dropped to about 200,000 for the Confederate Army.
