Final answer:
The Union's Military Plan's first component involved the organizing, arming, and disciplining of the Militia, with states having the authority to appoint officers and train the militia as prescribed by Congress.
Step-by-step explanation:
The content of The Union's Military Plan primarily involved the organizing, arming, and disciplining of the Militia. As per the instructions provided in the historical texts and contextual accounts, the first component involved ensuring the militia was prepared to execute the laws of the Union, suppress insurrections, and repel invasions. This strategy was critical for maintaining security and executing a military strategy that would allow the Union to employ force effectively during times of conflict.
The Union states were responsible for the appointment of officers and training of the militia according to the discipline prescribed by Congress. This approach to military preparation is reflected in the accounts of historical military engagements and was a cornerstone for ensuring that the Union could rely on its forces when national security was threatened.
During the Civil War, for example, the Union forces would employ a strategy of 'Total War' to disrupt the Confederate states' resources and morale. The reaction to Union forces by enslaved people and the subsequent actions taken by the Union army in regards to the enslaved individuals are also part of the historical focus related to Union military strategy.
