Undertakers in the 19th Century

[BettyO]

I have a question which someone may be able to answer here:

If a soldier died in battle and his body was shipped home, would it be embalmed in the field or would it be packed on ice and THEN shipped home to a local undertaker? What if the person died in winter? How would this be handled? If it had already been embalmed before shipping, would a local undertaker have to get involved to have it moved to the family's house for the funeral and burial?

Thanks!
