Just a quick question. If the British blockade is hurting the Union in terms of arms and powder, how the OTL CSA cope with these problems with the Federal blockade?
The Confederates made blockade running an industry essentially. They used Cuba and the Bahamas as ports where legitimate merchants would offload Confederate cargoes and then runners would dash into Confederate ports and offload the cargoes there. Similarly they exported roughly 900,000 bales of cotton (this an estimate from Battle Cry of Freedom) through the blockade, which by 1863 was worth 6x the price of pre-war cotton which was used to pay for guns, power and other necessities. They also printed frankly ludicrous amounts of money, which is what caused such massive inflation since the government was very adverse to raising taxes in 1861-62, which is what caused the Confederate currency to become essentially worthless by 1863.
The Union has it both easier and harder. They have an economy three times the size of the pre-war Confederate economy (far more diverse with 10x the manufacturing capacity) as well as a larger pre-war merchant navy to use to run the blockade or attempt to re-flag and engage in foreign cartels. They also have access to more natural resources than the CSA did, and they can, somewhat tenuously, back their currency in gold and have avoided printing vast amounts of money which means the greeback is still a viable currency. Meanwhile they have to deal with the fact that there is more difficulty running across the Atlantic than dashing from Cuba or Nassau.
