I've just finished painting up a couple of Confederate prisoners-of-war, which will be useful for 'rescue the prisoner' scenarios. I suppose they could also be 'walking wounded'. The figures are from Foundry. There is one more POW in the pack as well as some sentries, all to be painted at a future date.
If anyone is interested, you can see a size comparison of one of these figures, the new Steve Barber officer, and a couple of others in this blog.
