Just an observation on your first pic Joe....it is so set up and posed with lugers, the mauser, a sledge hammer, bayonets, and even a set of pincers. I guess it is just a statement as to how pissed off these guys were with the whole lice problem. Regarding the Civil War ant solution...a great deal easier to get rid of the ants by brushing them off than searching for the much smaller lice. I am sure that the ants would be very thorough. I see this as one of our ancestors more practical "green" solutions to a lice problem...let some other insect deal with the pest. Similar to today where they introduce one insect to eradicate another to protect crops.
