Final answer:
Both the Union and Confederate armies faced initial shortages of trained officers at the onset of the Civil War in 1861.
Step-by-step explanation:
At the outset of the Civil War in 1861, both the Union and Confederate armies confronted a dearth of trained officers. The sudden need to mobilize large armies strained the available pool of experienced leaders. Many officers resigned from the United States Army to join the Confederate forces, resulting in a significant shortage of experienced commanders for both sides. The professional military academies, such as West Point, were unable to churn out enough graduates quickly to fill these leadership gaps.
Consequently, both the Union and Confederate armies had to resort to rapidly promoting individuals who often lacked sufficient training or experience to hold high-ranking positions. This shortage of seasoned officers posed a critical challenge for strategizing and effectively leading troops, impacting the early stages of the conflict.
Correct answer: Both the Union and Confederate armies faced initial shortages of trained officers at the start of the Civil War in 1861.
