If you want to get technical about it, the rebels were better fighters and had the best generals but lost the war because they were an agrarian society fighting against the industrial north that had the steel mills,and other factories for making armaments.The "Confederate loyalists" CONTINUE to be losers as much today as they were when Lee signed at Appomattox.
Only thing missing on the Confederate flag today is the great big "L" in the middle.
And the north also enjoyed the fruits of southern society before the war.The South feed and clothed the north.They and their slaves.
How come blacks never pay homage to the fallen yankees that died for their freedom? Because they're to anti white and self centered.
