Concept for campaign - Vietminh/VC

[duff]

I'm thinking about designing a very long campaign played from the communist side of the Vietnam conflict.
Anything other than decisive loss would advance you to the next battle. Some battles will be quite easy and some would be unwinnable without heavy (probably unacceptable)casualties.

The decision about if and when to cut your losses would be a key challenge for this campaign.

Does it sound interesting? Is the idea of a campaign where part way through some battles the correct thing to do is cut and run too much against the spirit of SP? Thanks for any feedback or suggestions.
