Final answer:
Jefferson Davis and the Confederate Congress faced challenges in obtaining machinery and munitions and raising an army for war.
Step-by-step explanation:
Jefferson Davis and the Confederate Congress faced two major problems as they prepared for war. Firstly, they had difficulties in procuring machinery and munitions, which prompted Davis to send emissaries to the North to make purchases. Secondly, they needed to raise and equip an army. Relying heavily on volunteers in the early months of the war, the Confederacy struggled to handle the large number of people wanting to join. These problems posed significant challenges for the Confederacy's preparedness for war.
