I decided to post this thread here instead of the ASB one so that I'd get more people knowledgable of the ACW to help me.
I plan on writing an ASB Tl in which people with knowledge of the future try to provide some modern medical techniques and substances to the CSA in order to decrease the death rate of its soldeirs and POWs (with the knowledge that eventualy the USA will adapt to using them too and thus save more lives). In my story they'd rather keep how they got this info secret though. So how could I get the CSA to accept and use their knowledge and there materials (medical tools, drugs, etc.) within my TL while still being plausible.
To be specific some modern medical supplies I'd like to involve in the TL are, Prontosil, penicillin, the regular use of alcohol as an antiseptic and cleaning tool, and the use of extracellular matrices to heal wounds (plus the detergent and the process used to extract them from organic materials).
