Compare the strengths of the north and south in the civil war of the 19th century?

Comparison:

1) Technological superiority was on the side of the North;

2) Most of the fleet of the colonies was concentrated in the hands of the northerners, in connection with which, for the South, access to the sea was blocked;

3) The northerners outnumbered the southerners almost twice. But the southerners had a professional army, and the commanding staff was also good;

4) The US policy was vague at the beginning of the war, while the southerners, on the contrary, had a patriotic upsurge.

These factors were the reason for the successes of the southern army at the beginning of the war.
