In Vietnam many times, soldiers ran out of cRations, and they had few options........... One of those options was to scrape maggots off of scattered corpses, adding some vegetation to "give it taste" & serving it up was a common practice. Maggots, are very high in protein.
Bread and water, suddenly doesn't sound so bad.
(I'm not Vietnam age but some of the Goats I've met, as well as my Uncle Jimmy (sick bastage... Lord rest his soul), tell me it was the only thing they could do.)
