there was a movie about how dragons came up out of the earth and devoured everything. the movie is set in the UK. lots of FALs in the pic. sorry no name but somone here may have seen it.
over the years there have been a series of books published with jerry pournelle's name prominent. named THERE WILL BE WAR, some of the stories are about the small village of barley cross in ireland. a british army sergeant deserts with a tank as civilization collapses and winds up in barley cross. the disaster was a disease that made men sterile. this sergeant is immune and becomes "lord of barley cross" and practices the ancient "right of the first night" with all new brides in the hope of fathering a new generation. the stories are simply fantastic reading but i do not know the author or if they were ever published separately from the THERE WILL BE WAR series of books.
